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). The purpose of grinding differs with ...
