The process of crushing and grinding the mined ore to reduce the particulate materials from coarse feed size to fine product size as required by the downstream user is termed as comminution. It accounts for 53% of the mine site energy consumption, which is the highest energy step in mining operation. Comminution represents minimum of 10% of …
