2019/09/24· Applications of Ball Mill Certain uses of Ball mill are as follows: Grinding material such as coal, felspar, and pigments for pottery Blending of explosiveness Increases solid state chemical re-activity Helps in producing amorphous

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill ...

2015/06/19· If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill, then the same will be true for a 5.0 meter (15½ foot) diameter mill. At least ...

2018/05/12· It produces specified top size without the need for a closed-circuit crushing system. Produces relatively numerous size distributions with a minimum of fines due to self-classification. It has high reduction ratio and high capacity whether used for primary, secondary or tertiary grinding.

Grinding control strategy on the conventional milling circuit With the increase in ratio set point, a decrease in Cyclone 1 particle size is required. This control loop will increase the water to the sump to cause a decrease in cyclone
