It is a major component of belt conveyor for power transfer. There are bare steel surface, herringbone and diamond pattern rubber coverage on the surface of driving drum. Bare steel surface shall be adopted when the power is low, the belt width is small and the environment is dry. For herringbone pattern rubber surface, its friction coefficient is high, its slip resistance and drainage are excellent and it has directivities. Diamond rubber surface can be used for bi-directional operation conveyor.
        Driving drum is a major component of belt conveyor for power transfer. The modes to drive belt conveyor include single drum, double drum and multi-drum. Single drum is mainly used for the conveyor which power is not great, such as ground transportation of coal mines and coal preparation plant. Double drum is usually adopted for underground belt conveyor to make the structure of the conveyor compact.
        According to the materials, the driving drum is classified into 3 kinds including steel plate coiling weld, cast steel and cast iron. According to the structure, the driving drum is classified into 3 kinds including plate type, spoke type and the entire plate type. In addition, drum surface includes smooth surface, rubber coating type and rubber casting type; therein, the plate type rubber casting drum with steel plate welding and assembly has the most application environments.
