Roller installation: roller assembled should always test run coal mine rollers, check the rotation is flexible and immediate adjustment. On-site installation of roller bracket portion to be installed in the conveyor. Shall be laid before the conveyor belt: conveyor roller should always Coal mine roller prices, all kinds of roller installed in the specified location. Roller works: working coal mine roller roller supplier, relying on the tape between the rollers and the friction generated by coal mine roller mill, driven roller outer rotating cylinder, serve the purpose of supporting and drive. The size of the frictional resistance to rotation by the roller, belt weight, jointly determine the weight of the material. Minimize rotational resistance roller can effectively reduce the friction, thereby reducing power consumption.
