Open to lower batch of material to be ground into the pressure equalization tank. If the volumetric weight of the material to be crushed is sufficiently large, such a process can be performed well, and as soon as the lower valve is opened, the batch of material easily drops into the pressure equalization tank. . At that time, since the pressure in the pressure equalization tank is maintained constant,
