The ball mill will be equipped with different ball mill bearing systems based on its scale and work requirements. The most common ones are trunnion bearings and sliding shoe bearings, which correspond to trunnion bearing ball mills and sliding shoe bearing ball mills, respectively. Both types of ball mills have wide applications and provide ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media. They are smaller in size than SAG mills and can be used for smaller quantities of ore.
