The traditional grain grinder consists of two grinding pieces running at high speed to crush materials. Friction occurs between static grinding plate, material and dynamic grinding plate. The high temperature of the mill will lead to the following results:

1, the temperature of the machine working for a long time is too high for the operator to work continuously;

2. Due to the friction of the grinding disc, the temperature rises, and the material is burnt in the crushing process, which affects the original characteristics of the material. Even because of the high temperature, eating such grain flour is easy to get angry;

3. Due to the high temperature of the crushing cavity, the motor temperature is high through the conduction of the motor shaft, which often burns out the capacitor or motor.

4. Oily and sugary materials are mushy or liquid due to high temperature, which is not easy to crush.

5. Because the temperature difference is too large, the ratio of thermal expansion to cold contraction of various accessories is large, and it is easy to cause damage to the crushing cavity bearings and other accessories when running at high speed.

6. The sound of high-speed friction of the grinding disc is transmitted through the metal cavity, and the noise is particularly loud;
