Takes place in a sequence of crushing and grinding processes. • Size reduction ratio = Entry size Exit size The four basic ways of size reduction are by – impact – attrition, – shear,and – compression. • Crushing – ore is compressed against rigid surfaces in a rigidly constrained motion path. Reduction ratios of 3:1 to 6:1. Usually a dry process.
