DRY GRINDING ATTRITORS - Union Process

2020年12月31日  The Dry Grinding Process. The Attritor dry grinding process is achieved in a stationary tank by means of a rotating shaft and arms that agitate the media into a random state of motion of internal porosity called kinematic porosity. In this expanded condition, the media and particles are free to move, collide and impinge upon each other.
