After that, according to the material features and working conditions given, the whole structure of the belt conveyor was determined. Then it is the calculation and strength checking about selecting driving dev

The ordinary belt conveyor consists of six main parts: Drive Unit Work- ing part、Delivery End、Intermediate Structure、Loop Take-Up and Belt. As a result of underground working environment and the complexity of equipment operating conditions, it is necessary to consider every kind of possible working conditions during its
