This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Wet grinding is generally used in mineral processing operations because of the overall economies of operation. The advantages of wet grinding are: 1. It consumes lower power per ton of product. 2. It has higher capacity per unit mill volume. 3. It makes possible the use of wet screening or classification for close product control. 4. Get Price

Mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. Mineral processing involves four general types of unit operation: Comminution – particle size reduction (i.e. crushing, grinding, etc.) Sizing – separation of particle sizes (i.e. screening, classification etc.)

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
