The multi-point drive belt conveyor is also known as the middle power multi-point drive belt conveyor. In addition to the pulley drive device at the head of the machine, several sets driving devices are set in the middle of the conveyor. The characteristic of multi-point belt conveyor is that it can reduce the traction force of conveyor belt, and use ordinary braided conveyor belt to achieve the purpose of increasing the conveying distance.

There are two types of multi-point drive belt conveyor: (1) linear friction multi-point drive belt conveyor: it is to add one or more ordinary belt conveyors (auxiliary machines) under the original conveyor (host) belt to support the synchronous operation of the main conveyor belt, and reduce the traction force of the main conveyor belt by friction; (2) the multi-point drive belt conveyor with intermediate drum unloading type: it is installed in the A driving point is added in the middle of the original belt of a telescopic belt conveyor to reduce the traction force of the belt.
