The unit processes are usually characterized by certain chemical reactions such as roasting, leaching etc while unit operations are usually physical processes carried out discreetly on the ore. These physical processes are usually represented by crushing, grinding and similar such processes.
How it Works: Crushers, Grinding Mills and Pulverizers
— Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
Difference between Crushing and Grinding
