04/07/2019 · 04/07/2019 · S mills are autogenous mills that also use grinding balls like a ball mill. A S mill is usually a primary or first stage grinder. S mills use a ball charge of 8 to 21%. The largest S mill is 42' () in diameter, powered by a 28 MW (38,000 HP) motor. A S mill with a 44' () diameter and a power of 35 MW (47,000 HP) has been designed.

Introduction to Mineral Processing

AG mills employ ore as the grinding media. However, one the challenges with AG mills is that properties, such as hardness and abrasiveness, of the ore can vary, resulting in inconsistent grinding behaviour. The addition of steel grinding balls rectifies this situation. This approach is then termed semiautogenous grinding and

Influence of variations in feed ore characteristics on ...

In autogenous mills, the grinding media derives from the feed ore itself. Variations in feed ore properties will therefore affect the grinding charge and thus, the resulting ground product will vary. From a size distribution point of view, the optimum mill performance is achieved when there is a balance between coarse and fine particles in the ...

Open Circuit Configuration

IsaMill™ operations can take advantage of this feature which translates to an ability to use a low cost, but relatively low quality grinding media such as silica sand, river pebble, smelter slag or fine primary mill ss (autogenous milling). This means low media cost, with power efficiency still better than conventional grinding.
