1. The working part of the machine is the cutterhead. High speed particles are partially crushed after colliding with the toothed plate and are extracted by suction, while larger particles continue to collide and are extracted after being crushed. This reduces the load on the cutterhead, improves the grinding efficiency, and ensures even cooling of the powder.

2. The main advantage of this machine is its low temperature. According to thermal work equivalent: converted into 860 kcal of heat per hour of work. This machine is equipped with external ventilation. The air volume reaches 50m/KW, and most of the heat is taken away by the temperature difference between the inlet and outlet air. A small amount of heat is solved by water cooling. The inlet temperature of cold water should not exceed 25 ℃, and the outlet water temperature should not exceed 45 ℃. In summer, the cooling water flow should be increased appropriately to reduce the temperature.
