Fundamental Aspects of Crushing and Grinding

FUNDAMENTAL ASPECTS OF CRUSHING AND GRINDING. A basic study of crushing and grinding considers the physical properties of the material, the crushing mechanism itself, and its relation to the mechanism of failure. When a stress, which may be compressive, tensile, or shear, is applied to a solid, the latter deforms.
