Rock Crushers for Commercial Gold Mining Operations ...
Rock crushers are machine build to break large rocks into much smaller rocks, gravel, or sometimes rock dust. They are an important tool for most commercial mining operations. Rock crushers usually hold the rocks to be crushed in between two solid surfaces and apply a force that forces the molecule of the materials to separate or change alignment.

Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
FOOD PROCESSING
Primary processing is the conversion of raw materials to food commodities. Milling is an example of primary processing. SECONDARY PROCESSING Secondary processing is the conversion of ingredients into edible products - this involves combining foods in a particular way to change properties. Baking cakes is an example of secondary processing.
