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.
