The document advertises various metallurgical testing, engineering, and plant troubleshooting services available through 911Metallurgist.
At lower mill speed, fine particles that are floating are discharged due to the gradient difference between the inlet and outlet of the mill. Thus, the ball mill works at relatively low efficiency at lower mill speed, since the majority of particles moving at a low speed in the grinding section will not collide with higher energy.
