Laboratory rod mill is suitable for laboratory wet fine grinding of ore or other materials. It can also be used as ball mill by replacing its steel rods with steel balls. Output particle size of rod mill is uniform with high grinding efficiency and less over-grinding. Generally, laboratory rod mill is the most ideal equipment option when conducting experimental research on ore-dressing and fine grinding of ore with heavy sand. The laboratory rod mill is mainly composed of motor, main reducer (including balance shaft, hard tooth surface), transmission part, cylinder part, main bearing, slow transmission part, feeding part, discharging part, annular seal, thin oil Lubrication station, large and small gear jet lubrication, base and other components.

The motor of laboratory rod mill is driven by the reducer and the surrounding small & big gears, or the low-speed synchronous motor is directly driven by gears to drive the cylinder to rotate. An appropriate amount of grinding medium-steel rod is loaded inside the cylinder, under the action of centrifugal force and frictional force, the grinding medium is lifted to a certain height and falls down in a state of throwing or leaking. The materials are continuously delivered into the cylinder through the feeding port, and are smashed、sheared and crushed by the moving grinding medium, and the crushed materials are squeezed out of the cylinder by force of overflowing and continuous feeding for the next processing.
Application Industries & Fields
Laboratory rod mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass ceramics and other production industries, and it is specially suitable for wet or dry grinding various kinds of ores and other grindable materials.
