More+The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. the length of steel rod is 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8 1 the loading capacity of rod is about 35 45 of the effective volume ...
More+Rod mill. unlike the ball mill, the grinding medium in the rod mill is a steel rod, so the working characteristics are significantly different from those of the ball mill. since the steel balls are in point contact, the steel rods are in line contact. when the steel rods are sandwiched between the steel rods, the coarse particles are first ...
More+Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action, the rod mill uses steel rods lying within the drum and parallel to its axis. when the drum rotates, these rods roll around inside it, thereby crushing the feed material between them.
More+Unlike rod or ball mills, hpgrs reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. this forces the rocks against each other. there are no rods or balls that need replacing and it reduces energy consumption by about 40 for certain ore types, breneman said.
More+Rod mill products are generally coarser than those produced in a ball mill. because of these characteristics, the rod mill has also found wide acceptance by manufacturers of fine concrete aggregates, where rigid state or federal specifications must be met. rod mills are also used extensively in the grinding of chemicals, coke, limestone, slag, etc.
More+Our rod mills are available in multiple diameters to fit the needs of your operation. grinding, primarily by attrition, rod mills require comparatively low levels of power to operate. rod mills can be either wet or dry designs. once replaced by ag and sag mills, rod mills have had
