Ultra fine grinding of silver plant tailings of refractory ore …
Ultra fine grinding of the plant tailings of a refractory silver ore was studied using a laboratory type vertical stirred media mill. Preliminary tests confirmed that ultra fine grinding substantially improves the extraction of silver from the tailings in cyanide leaching (i.e. 36% Ag extraction rate from the as-received tailings with d 80 of 100 μm, c.f. 84% …

How to Choose the Correct GRINDING MEDIA
General rule #1: Feed particle size should be 90% < 10x bead size. Example: 2.0 mm bead will have a feed size of 90% < 200 micron. General rule #2: final particle size will be 1/1000th of media size. Example: 2.0 mm bead will give a D50 of 2.0 microns.

Energy-Efficient Advanced Ultrafine Grinding of Particles …
The concept of grinding media movement within a stirred media mill with a vertical grinding chamber was first published by Bosse, and it causes the media to cycle back and forth between moving closer to the disc stirrer, moving to the grinding chamber wall, and moving back to the agitator shaft, forming a cyclic movement.

laboratory vertical stirred mill. The grinding results show that changes in the feed size, stirring speed, and grinding media size are the primary parameters affecting the particle breakage rate. The test data also show that a finer product size is obtained when the mill operates at higher stirring speeds while using smaller grinding media.
