1. Introduction Comminution and industry drivers Comminution is the class of processes relating to the deliberate reduction in the size of particles. This is a critical and very energy intensive step in production of base metals, light metals, precious metals and iron ore which form the basis of our industrial and consumer economy.

More About Crushers. August 20, 2023. Crushers are used to break up large pieces of rock and bulk materials. The size of the eventual pieces depends largely on the type of crusher unit used; some models are designed to merely break large stones into manageable segments, while others are engineered to reduce an entire workpiece to dust.
