The ventilation of the bentonite milling machine is not good. Under the normal operation of the bentonite milling machine, due to the repeated impact and friction of the medium in the cylinder, the temperature in the mill continues to rise, causing the water-containing materials to generate water vapor. If the ventilation effect of the bentonite milling machine is not good, the water vapor cannot be discharged in time.

Water vapor will adhere to the bentonite milling machine liner and steel balls, resulting in paste ball or paste grinding phenomenon. Therefore, it is necessary to control the ventilation volume of the bentonite milling machine. The passing effect of the bentonite milling machine is good, which can not only bring out qualified fine materials in time, but also effectively reduce the phenomenon of over-grinding and reduce the temperature of the bentonite milling machine.

The feeding of the bentonite milling machine is unreasonable. During the operation of the bentonite milling machine, uniform feeding is a necessary condition to ensure the normal operation of the bentonite milling machine. If the feeding is too small, the impact of the steel balls of the bentonite milling machine will increase, resulting in waste of media; if the bentonite milling machine is fed too much material , it will cause insufficient grinding capacity of the bentonite milling machine, resulting in saturation, so it is necessary to strictly follow the feeding standard for feeding.
