Lm Description Description: Optical drive roller surface exposed steel surface, herringbone and diamond tread rubber cladding. Low power, small bandwidth, and the environment can be exposed when dry light steel surface. Herringbone pattern rubber surface friction coefficient, slip resistance and drainage is good, but there are directional. Rhombus rubber surface for bi-directional running conveyor belt conveyor drive roller are the main components of power transmission, the drive belt the way single drum, double drum and multi-drum of the points. Single drum used for power conveyor is not too large, such as ground transportation and coal preparation plant, etc.. Underground conveyor generally used double drum so that the conveyor is compact. Driving drum up points from the production of materials has rolled welded steel, cast steel and cast iron three kinds. Up points from a structure type plate assembly spoke, Spoke, the overall radiation plate three kinds. In addition, the cylinder surface is also smooth, coated, cast plastic and other types; Among them, the steel plate welded assembly spoke cast the most widely used plastic drum.
