Energy-saving rod mill for mineral processing plant working principle the transmission device drives the cylinder to rotate. materials and water are fed from the feeding end of the cylinder. ores are ground into fine particles by the grinding of steel rods, as well as the impact grinding of ores themselves.
The characteristic of the rod mill is that in the grinding process, the grinding medium is in line contact with the ore, so it has a certain selective grinding effect. product particle size is more uniform, less crushing ore grains. when used in coarse grinding, the processing capacity of the rod mill is larger than that of the ball mill.
Ball mill & rod mill design. in all ore dressing and milling processes, including flotation, cyanidation, gravity concentration, and amalgamation, it is necessary 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 grinding mill.Rod mills - mineral processing metallurgy. the type of mill that is used for grinding ore in a modern concentrator is the wet tumbling mill. these mills may be divided into three types rod mills, ball mills and autogenous mills. in the first type, the rod mill, the ore is introduced into the millgrinding mill.
