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.
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 :
In the continuous type Ball Mill, the material is being fed from the one end through its hollow shaft, while the crushed material comes out from the hollow shaft, at the other continuous Mills are used when the production rate is required to be high. Specially designed for ：Cement, Iron Ore, Copper Ore, Alumina, Cement, Calcium Carbonate, Bauxite, Calcium Carbide, Calcium Oxide ...
Low aspect mills are best suited to lowtomedium competent ores, while high aspect mills are more commonly used for competent ores either as singlestage circuits or autogenousball mill twostage circuits. The larger diameter and short length provide better impact breakage for the competent ore.
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc ...
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.
Metallurgical ContentOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating Costs The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This singlestage circuit is chiefly employed for coarse grinding when a product finer than 65 ...
