This machine achieves pulverization through the relative motion of movable steel grinding discs and fixed steel grinding discs with different geometric shapes under high-speed rotation, through shearing, grinding, and high-frequency vibration. The crushing chamber is equipped with two grinding zones, the first is the fine grinding zone and the second is the ultrafine grinding zone. The grinding fineness can be adjusted by adjusting the gap between the upper and lower steel grinding discs, which can effectively achieve the required ultrafine grinding effect in one go. This machine has the characteristics of compact structure, smooth operation, low noise, corrosion resistance, easy cleaning, and convenient maintenance. At present, it is an ideal equipment for wet crushing in China.
