crushing and grinding mine

Mineral and Mining Engineering: What are the differences of .Crushing and Grinding are a must in the Mining Industry, and indeed they are essential stages. The main target / purpose for both is to reduce the size of the ore (rock) particle before subjecting it to reagents (chemical reactions). Crushing invo.crushing and grinding mine,Crushing and Grinding Wet & Sticky Ore - 911 MetallurgistMar 19, 2017 . In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost.

Grinding is the second step of mineral processing and the last stage of the comminution process. The product from a crushing unit is fed to a mill in order to decrease the particle size (sometimes even to 10 microns) for subsequent processing. The reduction ratio is usually large (8 to 25:1 sometimes 500:1).
