Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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.
Copper Mining and Processing Processing of Copper Ores
Copper mining is usually performed using openpit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

Wide Application of Ball Mill Ball mill, as the key grinding equipment of the materials, is widely used for mineral grinding such as cement, lime, quartz, slag, silica, iron ore, copper ore, gold ore, bauxite, calcite, barite, gypsum and other minerals in mining, quarry, chemical, cement and other industries. Ball mill is the necessary equipment in ore beneficiation plant.
Ball Mills Mineral Processing amp; Metallurgy
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill amp; 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.

Double Stage Ball Mills. Occasionally, the liberation requirement for an ore requires very fine primary grinding. Usually, the most expeditious way to accomplish this objective is by double stage ball milling. Both mills are usually operated in closed circuit with separate classifiers.
Every machine saves 20% to 30% of electricity. ball Mill Of Mining Wet Grate Roling Bearing Energy Ball Mill Rolling Ball Grinding Equipment For this mineral processing equipment, a ball mill is widely used in beneficiation, building material and chemical industries. Ball mill is suitable for drytype ore grinding and wettype ore grinding.
