rod mills are very similar to ball mills, except they use long rods for grinding media. the rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.cylinder energy-saving overflow ball mill principle the main component is a cylinder with diameter and length at a reasonable proportion. driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder.It accounts for up to 40% of the total power consumption in mineral processing plant operations. so, selecting the efficient solution for grinding section is very important. prominer provides ball mill rod mill grinding system which is widely used in various types of ores beneficiation, electricity, cement and chemical industries.

dec 22, 2020 gold plant ball mill circuit operation very often in sag circuits, the ball-mill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sacrifice in grind, the focus shifts to throughput so much that the available ball mill power is not used to the fullest extent.the operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed through the central hole in the discharge cap or through the grid (mills with center unloading the ball mill shell dimensions VS motor sizes. 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.
