The rod mill is a grinding equipment with a long round steel rod as a grinding medium. The difference is that the former has a large aspect ratio (L/D), generally 1.5 to 2.0; the discharge end has no discharge grid, The discharge port is larger than the overflow ball mill in order to smoothly discharge, load the rod and take out the broken rod and the bent rod. The 100-mine method of the rod mill can be divided into three types: overflow type, end-end discharge type and middle-end discharge type. The surrounding ore grinding mill has a faster discharge rate, the product has a coarser grain size and a lighter degree of pulverization; the central peripheral concentrating mill is fed simultaneously by both ends, the discharge rate is faster, and the product granularity is coarser. The rod mill can be used for dry or wet work; the surrounding mine type is also used for wetting and grinding operations. The rod medium used is round steel rods of different diameters, the length of which is about 100~150mm shorter than the barrel of the mill; the diameter is generally 60~120mm; it is too thick and easy to smash the mill liner, which is easy to break after being too thin and worn. . When the rod mill is in operation, the rod and the rod, the rod and the material are in contact with each other, so the "selective grinding" effect is strong, the product granularity is uniform, and the material is excessively pulverized. The rod mill is mostly used for the treatment of brittle materials, such as the re-election of tungsten and tin ; it can also be used for the pretreatment of the ball mill feed to reduce the particle size of the ball mill; it can also be used for the preparation of pellet materials.
