بيت /grinding ball mill proces description
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

Steel balls produced for the bearing industry are often made in standard bearing steel 100Cr6 – AISI 52100 (HRC = 6066) and are produced through a standardized process, of which grinding is a key operation. The diameter of balls range from very small () to large (300 mm), with a majority of 2030mm. RAW MATERIAL

The mill is best used to crack whole grains with a minimum of "fines". It is not used as a final process for reducing the size of ingredients used in fish feeds. Screening. Associated with grinding feeds for fish fry, a sieving system is required which classifies materials to any desired particle size.

Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

Description. The principles of grinding are well established: the preground liquor is pumped through the ball mill's grinding vessel in one or more stages. The refining action is accomplished by a special shaft with agitator arms and diverters rotating in a vertical jacketed grinding tank, which is filled with hardened steel balls. The various layers of grinding elements move in the .
