CRUSHING and GRINDING, SCREENING EQUIPMENT

Crushing and grinding equipment are used for size-reduction of a variety of materials. The selection of these type of crushers are based on the material hardness and required reduction ratio, and the economics of the equipment in terms of investment cost and operating cost. At SIKO, we have the capability to design and.

COMMINUTION. Comminution entails reducing the particle size of the raw material by crushing, grinding, and milling or fine grinding. In mineral processing parlance, comminution in coarse range is known as. “crushing” and in fine range it is called “grinding”. Comminution : The act or process of reduction of particle size.

rock or particle of a known size and the reduced particle size after the comminution process has taken place. The amount of energy required to do this work is referred to as the 'Work Index' and it is an expression of the resistance that a material has to crushing (or grinding). It is a measurement of how hard the ore is.
