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 …

Precision grinding is the process of removing metal from a workpiece to achieve a specific size, shape, or surface finish. Surface grinding is a type of precision grinding that is used to create flat surfaces on metal workpieces. This process involves using a grinding wheel to remove tiny bits of material from the surface of the workpiece until it is smooth and flat.
