Small Scale Gold Mining Equipment Ball Mill Grinding Rock Grinder Mill
Ball Mill Introduction
Ball mill is suitable for all ore dressing and milling operations, including flotation, cyanidation, gravity concentration.
The working principle is to Crush and Grind, often with rob mill and ball mills, 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.
In present day practice, ore is reduced to a size many times finer than can be obtained with crushers. over a period of many years various fine grinding machines have been developed and used, but the ball mill has become standard due to its simplicity and low operating cost.
Ball Mill Structure
Notes of above pictures:
Picture1-Professional Machine Tool for making the drum of ball mill, rotary washing plant and trommels. It will improve the concentricity rate, and cut down the machine error.
Picture2-High manganese Steel Liners. When the minerals are grinding in the ball mill, the liners will easy to wear out. So using the manganese Steel Liners will make the ball mill wear-resisting.
Picture3-Steel Balls. They are the main medium for grinding the minerals in ball mill.
Picture4-Ball mill Motor and Reducer. It will keep the ball mill rotating in a uniform speed.
