Safety Precautions

Sources of harm to avoid

The mixer has three main sources of harm:

1. Mechanical Injury

Mechanical hazards from the mixer originate from various components such as transmission parts, agitators, and hinged doors—specific areas will be clearly marked in the manual.

2. Electric Shock Injury

The electrical shock injuries from the mixer originate from the motor, control cabinet, cables, and cable connections.

Third, temperature damage

The temperature-related damage to the mixer can originate from the temperature control kit, the fluid coupling unit, and potentially from various transmission components as well.

Basic Principles for Safe Operation

1. Absolutely no touching of moving transmission parts or mixers with the human body, and be cautious of dangerous behaviors such as accidental falls or collisions.

2. The mixing equipment is a forced-mixing device; during maintenance and cleaning operations, ensure that the main power supply is switched off, and take precautions to prevent anyone else from turning the main power back on.

3. Electrical connection, wiring inspection, and maintenance of the control section must be performed by qualified electricians; unauthorized personnel are strictly prohibited from operating.

4. Do not remove the safety protection devices that come with the equipment itself, and perform safety checks according to the notes in this manual.

5. Avoid all heat source areas and strictly prohibit direct physical contact. Also, ensure that no person stands in the potential splash paths of any components.

6. Ensure that all hinged moving parts are protected against pinching or injury when opening and closing.

7. Users should establish a post responsibility system and strengthen their awareness of safe production.

Safety warning areas on the equipment

Attention

This manual uses line drawings to illustrate the external shapes of the vertical mixer under different structural configurations. While the illustrations may vary slightly from the user’s custom-designed equipment, this does not diminish the importance of safety considerations applicable across all structural designs.

Our company customizes equipment according to requirements, selecting or omitting certain safety devices and protective measures based on different manufacturing (and usage) standards. However, during operation, such risks should still be avoided.

1. Electric Motor Impeller Guard

From equipment installation through to the start of production, there is no need to remove the motor impeller guard. The guard may only be taken off temporarily during maintenance for calibration purposes. Therefore, unauthorized or non-professional maintenance personnel must not dismantle this guard. After maintenance is completed, the guard should be promptly reinstalled and secured—never allowing the equipment to operate with the guard removed.

2. Grounding electrical appliances or equipment

A complete grounding system must be installed to prevent accidental leakage, short circuits, and static electricity from causing harm to individuals.

3. Emergency Stop Button

In the design of electrical control systems, an emergency stop button should be included and installed near the mixing equipment, ensuring it is easily accessible so that the equipment can be immediately shut down in case of malfunction.
If the control cabinet is installed near the mixing equipment, an emergency stop button can be directly mounted on the control cabinet.

4. Protection for the Feeding and Cleaning Ports

The manually operated door installed on the cylinder features direct feed-in and cleaning openings, along with corresponding safety measures such as safety switches or barrier grids.

On equipment equipped with safety switches, two measures are implemented to ensure personal safety: 1) When the door is opened, the mixer cannot operate; 2) If the door is opened while the mixer is running, the mixer will immediately stop. These functions must be coordinated with the electrical control cabinet to be fully realized.

The hybrid device, designed for no-load startup, features a densely packed, heavy-duty grating or a dedicated manual feeding mechanism at its manual feed inlet, effectively preventing personal injury.

The safety grilles on cleaning doors or feed openings must not be removed during the production process.

Basic information about the equipment

Scope of Application

The mixing screw homogenization tank is widely used in blending processes involving powders with powders, granules with granules, or powder mixed with liquids—in industries such as chemicals, agrochemicals, dyes, food, battery materials, rare earths, and rubber-plastic materials.
1. The homogenization tank cylinder must meet the stringent requirement of ensuring no residual material remains during discharge of the mixed contents.
2. Gentle stirring methods prevent damage to fragile materials such as crystalline substances.
3. The mixing efficiency of the homogenization tank, combined with its ability to facilitate chemical reactions in materials while maintaining low energy consumption, leads to improved process performance.

How it works

The mixing screw homogenization tank uses an internal stirring screw to lift materials from the bottom, enabling uniform flow throughout the tank and ensuring efficient material blending and homogenization.

Special Note

During the device configuration process, the following situations either exist or need to be configured. The configured hybrid device will differ from a standard hybrid device and must be explicitly noted:
1. The raw materials contain hard particles with a particle size exceeding 2 mm;

2. Material specific gravity is greater than 2;

3. Material particle size exceeds 500 mesh;

4. The dry powder material has a relatively high moisture content, appearing damp, hygroscopic, or exhibiting adhesive properties.

5. When the equipment needs to be heated to temperatures exceeding 120 degrees;

6. The materials have special properties such as heat release, steam generation, flammability, explosiveness, and tendency to stick or clump.

7. When mixing two materials with a specific gravity difference exceeding 1 to 20 or a particle size difference greater than 1 to 100;

8. Requires equipment capable of vacuuming or maintaining a negative pressure state;

9. When compressed gas is introduced into the equipment cylinder, creating pressure;

10. Material properties such as particle size, hardness, and irregular shapes can easily lead to equipment wear;

11. Processes where materials cannot come into direct contact with metal;

12. When mixing materials, first add the materials and start the equipment at full load;
Do not stir non-fluid materials such as paste-like or solid/semi-solid oily substances.
Do not stir materials with excessively high viscosity.
Materials with a formulation ratio lower than 1:1000 cannot be handled directly.

Cannot handle materials that solidify and harden within a short period of time.

Cannot handle unstable materials such as explosives.

The following factors highlight the differences in equipment:
Equipment materials, surface treatments, startup methods, motor power, gear reducer configurations, spindle seals, equipment speed, cylinder inspection openings, discharge valves, temperature-controlled jacket systems, maintenance doors, liquid spraying mechanisms, liquid injection flow rates, power supply characteristics, and protective measures, among others.

Equipment Installation

Equipment lifting and installation

The standard practice for stirring and homogenizing tanks is to use suspended lifting, and all operations must follow specific procedures, carried out exclusively by professionally trained personnel qualified to work with special equipment.
The cylinder of the mixing screw homogenization tank is equipped with dedicated lifting holes. Use lifting devices that comply with relevant safety standards, and employ lifting equipment with appropriate capacity, as shown in the figure. Ensure proper control of the center of gravity during the lift, and after hoisting, proceed slowly to maintain stable movement.
Personnel should remain in a safe area during operations, and standing directly beneath lifting equipment is strictly prohibited.

Equipment Foundation Installation

As an intermediate process equipment, hybrid devices typically require a supporting structure to elevate and position the equipment at an appropriate height above the ground, ensuring it meets the process design requirements of the production workflow.
The homogenization tank is supported by three pairs of ear supports and horizontally fixed to the steel-structure platform.
The platform's design should account for resonance phenomena caused by operating hybrid equipment, ensuring that it does not interfere with the performance of other devices or the weighing equipment itself.
The platform's design capacity typically ranges from 2 to 3 times the weight of the equipment—specifically, the equipment's weight plus the weight of the materials being mixed, as well as any additional attachments mounted on the device.
The installation of the large-scale mixer should take into account the mixer's diameter and height, as well as lifting considerations during the overall plant construction.

Precautions during installation

During the installation process of the flow system, the various pieces of equipment within the flow must be arranged in a specific sequence for installation.

When fabricating the equipment's foundation structure, attention should be paid to ensuring the installation position is level and properly aligned. During equipment placement, shims can be used to adjust the equipment's horizontal alignment, helping to prevent potential malfunctions caused by improper leveling.

The equipment's safety bolts and the foundation bolts for the platform columns do not use spring washers for anti-loosening; instead, they employ a double-nut system to prevent loosening, while also reserving approximately 3 to 5 extra threaded positions for future use.

When the equipment needs to be installed on a steel-structure platform, a rubber plate can be added between the equipment base and the mounting plate to reduce vibrations during operation.

When installing the equipment, pay attention to its orientation, ensuring that the installation adheres to safety principles while also optimizing production efficiency, facilitating maintenance and repairs, and enabling easy cleaning and upkeep.

The steel-structure platform should be equipped with comprehensive protective measures, such as fences.

When installing the equipment, ensure that no installation tools or other debris fall into the equipment cylinder, and take precautions to prevent them from getting stuck in the various transmission parts of the spindle.

The installation components used during installation are either provided by the user or prepared by the installation company.

If the equipment is not installed or used for an extended period, it must be stored in a dry, well-ventilated, and cool environment, with proper measures taken to prevent slipping and ensure stable operational balance.

Equipment power installation

All operations related to the circuit must be carried out by qualified professionals. Ensure strict adherence to standards by selecting high-quality electrical components and cables of appropriate capacity for circuit installation.

The starting control systems for mixer equipment come in a variety of configurations, including star-delta start, variable-frequency start, reduced-voltage start, and direct-on-line start, depending on the specific operating conditions.

When installing power supplies for hybrid devices, the power lines must be thoroughly inspected to ensure no phase or voltage mismatches occur.

All hybrid devices have a fixed rotation direction. During equipment debugging or after power installation, briefly press the start button to check whether the device's rotation direction matches the label sticker on the equipment. If the rotation is reversed, simply swap any two of the three-phase wires connected to the motor junction box, then perform another brief test to verify the correct rotation direction.

After installing the power supply, all buttons and indicator lights on the electrical control box should be checked for proper functionality. If any component fails, address the issue promptly—do not proceed with direct use of the mixed equipment.

The basic configuration of the electrical control box should include the following components: a 3-phase ammeter, a voltmeter, a converter, 3-phase power-in indicator lights, a start button, a start indicator light, a stop button, and a stop indicator light.

Attention

Your equipment, as per the contract agreement, may not include an electrical control box. Please proactively request the equipment control circuit diagram from our company, and ensure that customization is carried out by a company or employee with professional qualifications. All components and the enclosure must comply with the relevant safety standards.
If equipped with a dedicated circulating oil pump for the gearbox, power-on operation should be performed to ensure it starts automatically when the motor is activated. Otherwise, the gearbox may run without proper lubrication, directly leading to its damage.
If the equipment is equipped with a variable-frequency dedicated motor, the motor fan should be powered independently and must not be connected in parallel with the main power line supplying the inverter and the variable-frequency motor. Otherwise, the motor is likely to overheat and burn out.

Equipment debugging

Instructions Before Debugging

At the time of出厂, all equipment has undergone a one-hour no-load test to meet quality inspection standards. After reviewing the equipment's manufacturing requirements, it is then released for shipment.

After users have completed the equipment installation, they still need to perform an unloaded trial run. If the equipment has been stored for an extended period or if more than 3 months have passed since it was manufactured before being put into operation, a low-speed, unloaded trial run should be conducted—or alternatively, the mixer blades of the blending unit can be manually rotated by hand as a test. Regarding the debugging process, this includes functional attachments such as shear knives. However, if the blending equipment lacks these configured attachments, the corresponding steps for this component can be skipped altogether.

Attention

During all types of debugging, please use the raw materials required for production for testing—do not substitute them with any other materials. The materials used must fall within the operational range of the mixing equipment. If hard, blocky materials or installation tools happen to drop into the mixing device and become trapped inside, they could cause critical damage to the equipment, potentially leading to its complete failure and rendering it irreparable.

After the mixed equipment installation and debugging are completed, it is still necessary to clean the interior of the equipment. Additionally, before formal production begins, multiple cycles of material mixing can be performed to thoroughly remove any residual powder impurities that aren’t part of the raw materials. Equipment requiring high hygiene standards should undergo sterilization procedures.

During all types of debugging, operators and on-site inspectors should not leave their posts until the debugging is complete.

Various types of debugging cannot be performed out of sequence, nor can they span across time.

When the equipment leaves the factory, the gearboxes have not been lubricated with oil. Users should add lubricant themselves before using the equipment; otherwise, operating the gearbox without proper lubrication will directly cause damage to the unit.

Prepare homework

Follow the lubrication guidelines outlined in the Maintenance and Care section of this manual to correctly add lubricant to the gearbox, and ensure that all lubrication points on the equipment are properly greased.
If the equipment's gearbox is equipped with a lubrication oil circulation pump, ensure that it powers on and operates properly; otherwise, the gearbox may suffer from localized lack of lubrication, leading to damage of the reducer.
Inspect the inside of the simplified equipment and check for any potential debris or tools in its various transmission parts, and clean the exterior of the equipment. Ensure that any inspection doors installed on the equipment are securely closed and locked.
Check whether the equipment's power supply is functioning properly, including the main motor power, discharge valve power, safety device power, and more.
Turn on the gas supply valve and check whether the gas sources used by the equipment—including the discharge cylinder and the air-sealing device—are functioning properly, as well as the pressure levels and the power supply to each solenoid device.
Adjust the device's startup parameters, such as the switching time for star-delta starting and the starting frequency in variable-frequency drive mode, among others.

Functional Component Testing

After powering on the equipment, you should first check whether the functional accessories are operating properly. Open and close the mixer discharge valve, adjust the compressed air flow to an appropriate level, and ensure stable opening and closing performance. Finally, verify that the signals from each safety device are functioning correctly.

All accessories installed on the equipment, such as sampling valves, level indicators, thermometers, and others, must be verified before the equipment's main shaft is started for no-load testing.
After the attachment has been inspected, briefly press the main motor’s start button to check whether its rotation direction matches the label indicated on the equipment cylinder. If not, make adjustments promptly.

No-load commissioning

After the equipment completes preparatory work and functional debugging, it enters the no-load commissioning phase.

Proceed step by step according to the following method:
1. Energize the main motor power supply for the mixer.
2. Run the mixer for 5 minutes, continuously monitoring for any unusual or disruptive noises during operation. If such noises are detected, immediately stop the equipment. Also, check whether the operating current is within the normal range; if not, promptly use the stop button or emergency stop button to cut off the power.
3. Ensure the mixer is running normally. After continuous operation for 1 hour, inspect all parts of the mixing equipment for overheating, vibration, or unusual noises. If any of these issues are detected, take immediate action.
4. Before stopping the operation of each motor in the mixing equipment, simulate the discharge process by briefly opening and closing the discharge valve several times to verify its functionality.
5. If safety devices, such as limit switches, are specifically installed for the equipment, they should be verified at this time. When the protected component is triggered, all power sources of the hybrid equipment must be able to cut off power immediately; otherwise, power supply should be stopped immediately, and the control circuit should be inspected.

Check after debugging

During the debugging process and after debugging has concluded, inspections will be conducted on the following areas:
The temperatures of the main motor and main gearbox should both be below 50 degrees Celsius.
The inner surface of the cylinder, the edges of the ribbon, and the paddles show no signs of friction;
Current conditions during no-load commissioning of motors in each component;
There are no signs of looseness in any of the connecting bolts or anchor bolts on the equipment.

Load Testing and Debugging

The equipment has completed preparatory work and undergone functional and no-load debugging; only after confirming no abnormalities can it proceed to the load testing phase.
To smoothly complete the equipment's load commissioning, operators should familiarize themselves with all of the equipment's controls during the no-load debugging phase. Additionally, multiple no-load test runs can be conducted to master the operational sequence and emergency stop procedures.
Load debugging requires adding materials to the mixing equipment, so either feeding equipment needs to participate in the debugging process, or materials must be added manually. The materials used must be free of any foreign objects, and their properties in all aspects should align with the operational range of the mixing equipment.

Please follow these steps:

1. Start the main motor of the mixer;
2. After observing no abnormalities, proceed with filling and adding materials;
3. The added materials should be within the operational range of this equipment.
Additionally, it can be tested with 50% and 100% of the rated mixing capacity, with each trial run lasting at least 1 hour.
4. During the test run, if any abnormal conditions occur, the equipment should be immediately stopped using the stop button or the emergency stop button in case of an emergency.
5. After a normal test run, open the discharge port to empty the material from the mixing equipment, then stop the mixing device.

Check after debugging

During the load debugging process and after the debugging period ends, checks are conducted on the following aspects:

The temperatures of the main motor and main gearbox should both be below 60 degrees Celsius.

The inner surface of the cylinder, the edges of the ribbon, and the paddles show no signs of friction;

Current conditions during no-load commissioning of motors in each component;

There are no signs of looseness in any of the connecting bolts or anchor bolts on the equipment.

Re-trimming initiated for commissioning

At this stage, only specially designed equipment capable of overload startup can perform the task. During commissioning, the process should follow these steps: preparation, functional accessory testing, no-load testing, and finally, loaded testing—only after completing all these stages is the overload startup performance test permitted.
Hybrid devices equipped with overload-start capabilities will have corresponding structural differences in their configuration. During debugging, operations should be performed based on the actual configuration method used.

Please follow these steps:

1. Load the mixing equipment with materials that meet the specified requirements.
2. Start the spindle motor of the hybrid device. If the device fails to stir after being powered on, immediately cut off the power supply and notify our company’s after-sales service personnel for assistance. Do not continue supplying power blindly, as this could directly cause the motor to burn out.
3. After the hybrid equipment is running normally, please directly apply the loaded commissioning method for inspections in all aspects.

Occupational Safety and Health

Safety Precautions During Labor

When operating mixed equipment, be sure to pay attention to the designated warning areas marked on the equipment.

Equipment with removed safety devices must not be used.

When operating mixed equipment, climbing on the equipment for any purpose is strictly prohibited.

When the mixed equipment is running, no tools may be used to reach into the equipment through the feed opening.

When cleaning, repairing, or lubricating equipment, be sure to disconnect the power supply and use warning signs or lockout/tagout procedures to prevent unauthorized personnel from turning the power back on.
When personnel enter the mixer for operations, they should adopt appropriate protective measures, including wearing a filtering respirator and protective goggles. For large-scale equipment, ensure adequate ventilation inside; if necessary, use a blower to facilitate air exchange.
Establish safety production regulations and implement reasonable measures to ensure personal safety.

Plans and Responsibilities

Use equipment that has been properly debugged for production, and establish a series of pilot production plans to better coordinate and align the various stages of the manufacturing process.

Establish a job responsibility system and assign trained professionals to perform all equipment operations. Implement a rational division of labor to ensure the smooth completion of production tasks.

Preparation Before Material Input for Production

Before powering on the electrical control system, check whether the cylinder is ready for production and verify if the surrounding equipment meets the necessary production conditions. Also, clear away any obstructions or debris.

Check whether the maintenance doors installed on the equipment and the safety devices are properly in place. After completing the hardware inspection, turn on the switch of the electrical control box and verify that the supply voltage and phase sequence are normal.

Check whether the lubrication oil circulation pump for the accelerator can power on normally. If the mixing equipment is equipped with pneumatic discharge or pneumatic sealing devices, first power on the compressed air source and verify the air supply pressure at each point.

The pneumatic discharge valve requires an air pressure of at least 6 kg (0.6 MPa).

The pneumatic sealing device uses air pressure of approximately 4 kg (0.4 MPa).

Pre-production no-load simulation test

Start the mixer spindle motor and check for silent operation to determine the prerequisites for production of the mixing equipment.
The hybrid device is running; open and close the discharge valve.
Performing the basic discharge operation for mixed equipment.
Testing additional supporting equipment, such as dust collectors.
Test whether the finished material handling equipment is operating properly.
Only after the no-load simulation is completed are operators permitted to proceed with normal production involving material feeding.

Material Feeding Production Operation

The single batch weight of the mixer should meet two criteria:

1. The volume of the material submitted should be between 40% and 70% of the mixing equipment cylinder's storage capacity.
II. The weight of the materials submitted must be within the capacity of this mixer.
Initially, the configuration of the mixing equipment is determined by first selecting the size of the equipment cylinder based on the volume of material to be mixed in a single batch. Then, according to the material's specific gravity, the weight of the material per batch is calculated to determine the required load capacity of the mixing equipment—such as motor power and spindle size.
The specific gravity of the materials added to the equipment must not exceed the originally preset allowable weight.
The load-carrying capacity of a hybrid device cannot be determined solely by the specific gravity of the material—factors such as the material's coefficient of friction and particle size can also significantly influence the equipment's operational performance.

The production feeding operation for conventional equipment should be:

↓ Close the equipment discharge valve
↓ Operate the equipment's stirring shaft
↓Perform material feeding operations
↓ Conduct mixed operations
↓Mixing time completed
↓ Open the equipment discharge valve
↓ Material discharge completed
↓ Turn off the machine spindle
↓ Finish homework

In actual production operations, the following aspects should be noted:

1. If the mixing equipment is equipped with a manual discharge valve, or if the discharge valve lacks an installed stroke-position interlock signal, ensure that the discharge valve is closed before feeding materials into the system.
2. The mixing equipment is currently running with material inside. Unless there’s an unexpected issue requiring immediate shutdown, the equipment should not be stopped arbitrarily—otherwise, equipment not designed with robust overload-start capabilities may fail to restart altogether. If an emergency stop occurs, it will be necessary to remove some of the material from the mixing unit until the equipment can resume operation normally. During this restart process, care must be taken to avoid continuously overloading the motor, as doing so could directly lead to motor burnout.
3. The discharge valve configured for the equipment varies in its material-specific discharge time; therefore, during trial production, a reasonable material-release timing should be estimated.
4. When adding liquids during the mixing process, they should be introduced in a spray form; otherwise, it may easily lead to uneven mixing or clumping.
