Crushing Vs Grinding Minerallurgy

For crushing no grinding media is required, the ore size is reduced by external forces applied by the crusher. Dry crushing but wet grinding. Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling.

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Ore processing Waihi Gold

The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.
