Grindforce Back to Basics Outotec

There are two major types of grinding mechanisms in attrition type stirred, milling machines, namely; 1. shear stress between two surfaces, which is stress parallel to a surface of material, like grinding media or mill wall).; 2. compression between two surfaces, which is stress perpendicular to a surface of material.
