Chapter 1: Overview of Horizontal Mixers

I. Working Principle:

The horizontal mixer features a dual-layer helical blade arrangement on its drive shaft: the outer blades convey material toward the center, while the inner blades push material outward. Thanks to the counter-current motion created by the dual-layer spiral belts, the mixer generates a low-energy, highly efficient mixing environment. Material is continuously circulated as it’s driven both inward and outward by the spirals mounted along the mixing shaft, enabling the agitator to achieve maximum tumbling action throughout the entire contents of the mixing drum. During operation, the inner spiral causes material near the central axis to rotate around the axis itself, moving axially from the center outward. Meanwhile, the outer spiral propels material closer to the drum walls to rotate around the axis, pushing it axially from the sides inward. As a result, the materials are thoroughly and uniformly mixed within a remarkably short time.

II. Structure:

This series of models consists of U-shaped or cylindrical barrel bodies, a frame, a drive motor, a stirring blade shaft, heating/cooling devices, a dehumidification system, and an electrical control box, among other components.

Chapter 2: Machine Installation and Operating Instructions

I. Installation:

Step 1: The stationary horizontal mixer should be installed on a sturdy base. For long-term use, anchor bolts should be embedded; for short-term use, timber sleepers can be laid under the base and properly leveled to ensure stability.

Step 2: Inspect the transmission mechanism, working devices, brakes, and other components to ensure they are securely fastened and reliable, guaranteeing normal operation. Protective covers should be installed on parts such as the large gear ring and pulleys.

Step 3: Aggregate specifications must match the mixer's performance; materials exceeding the permitted range must not be used.

Step 4: Add gear reducer-specific lubricant to the gearbox.

Step 5: Run the empty vehicle, check the rotation direction of the mixing drum or agitator blades, as well as the operation and braking of all working mechanisms. Only after confirming everything is normal can you begin actual operations.

II. Precautions for Use:
1. When feeding materials, it is strictly prohibited to reach your head or hands into the space between the hopper and the machine frame to check or feel the feeding situation. While the machine is running, never insert your hands or any tools into the mixing drum to scoop out or discharge the material.

3. Do not stop the machine midway or start the mixer under full load; instead, add materials only after the machine has been turned on.

4. If an accident or malfunction occurs during operation, immediately cut off the power supply, clear the contents from the barrel completely, and then proceed with repairs.

5. After work, ensure thorough cleaning and maintenance of both the inside and outside of the mixer, as well as tidying up the work area.

Chapter 3: Maintenance and Care

1. During machine operation, if any issues such as poor material flow or blockages occur, immediately stop the equipment. Remove the blocked materials or debris inside the machine and thoroughly clean the unit.

2. During the machine rinsing process, be sure not to splash water onto the motor, heating element, or switch components, as this could cause damage if the machine is subsequently turned on.

3. Conduct a comprehensive inspection of the equipment every three months, checking mechanical components for wear, looseness, and other issues.

4. If the machine needs to be shut down for an extended period, it must undergo a more thorough cleaning, and the main power supply should be disconnected. Before restarting, make sure to inspect the electrical components before reconnecting the power.

5. Lubricate the bearings with grease once every three months (using a grease gun).

6. Replace the gearbox gear oil (refer to the last page of the instruction manual).

Gear Reducer Maintenance Operating Procedures

Cylindrical gear reducers typically use GB5903 medium-load industrial gear oil.
