Granulator cutter rolls need to meet different user needs. The choice of blade material chemical composition for cutting different objects requires a suitable blade angle, maintaining blade sharpness while ensuring sufficient strength to prevent chipping during use. A good heat treatment process is carried out to achieve suitable hardness and minimal internal stress, preventing deformation during use.

　　Granulator cutter rolls offer numerous performance advantages, fully leveraging their strengths during operation, hence their popularity among users. Today, we will introduce the main components of granulator cutter rolls for a better understanding.

　　Twin-screw air granulator cutter rolls originated in the 1930s. It consists of a pair of intermeshing parallel rotors and a housing. It draws in, compresses, and discharges air according to volume changes during operation. The mechanical structure is extremely simple, with high mechanical reliability, excellent dynamic balance, and convenient operation and maintenance. By the 1970s, twin-screw air granulator cutter rolls had become perfected and mature, becoming the dominant product on the market. Currently, screw-type air granulator cutter rolls produced by well-known domestic and foreign granulator cutter roll companies are almost all twin-screw.

　　The magnetic reactor uses a static sealing structure, connected to the motor drive via a magnetic coupling device. The static seal replaces the dynamic seal due to non-contact torque transmission, completely solving the leakage problems previously unaddressed by mechanical and packing seals, allowing all shearing parts of the entire medium to stop working under absolute sealing.

　　The magnetic reactor mainly consists of a heating furnace, reactor body, reactor cover, and granulator cutter roll.

　　(1) The heating furnace is used to heat the reactor. The external cylindrical furnace uses a cylindrical silicon core, characterized by good heat transfer and rapid heating due to the passage of heating resistance wires. The bottom of the furnace has a socket, connected to the controller via a cable during use.

　　(2) The reactor body and flange are connected by threads. The seal between the reactor body and the pot lid is formed by an arc-shaped surface and a conical line, eliminating the need for a heating plate. A sealing effect is achieved through high processing precision and the tightening force of the main bolts.

　　(3) The pot lid is a major component of the magnetic reactor. The material is 1Cr18Ni9Ti. The pot lid has a pressure relief valve, valve, sampling valve, and cooling coil, allowing for real-time control of the material reaction state within the magnetic reaction section, adjusting the material composition, ratio, temperature, and pressure within the magnetic reaction section to ensure the safe operation of the magnetic reaction section.

　　(4) The granulator cutter roll uses permanent magnets, consisting of inner and outer annular magnets with a pressure pad in between. A servo motor transmits the shearing torque through the magnetic force of the inner and outer magnets, and the pad is equipped with a speed measuring component. When rotating with the inner magnet, the electronic components generate a detection signal and send it to the controller to display the operating speed of the granulator cutter roll.
