Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
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 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.
Semiautogenoussingle stage. These circuits are not a good choice for many orebodies because it is not logical to expect one machine to be as efficient on 150 mm ore as it is on 100 micron ore. Semiautogenous plus ball mill has been the "work horse" of mills. SAG vs Ball Mill Advantages . AG SAG Mill Grinding Compared – Which is Best

Ball mills are used for wet grinding iron ore, g old/copper ore, nickel ore and other ores, as wel l as lime/limestone for flue gas desulphurisat ion systems, coal and other raw materials. Rod mill :
F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term ''rod mill'' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
