First gave a brief introduction on belt conveyor。 Then the principle of selection and method of calculation。 then designed it as the given parameter based on the method of design and selection, and checked the selected major ponents of the conveyor. Common belt conveyor consists of six major parts: transmission, tail and return device, the central rack, tensioning device and conveyor belt. Finally, simply describes the installation and maintenance of conveyor. At present, the belt conveyor is for long distance, high speed, antifriction. One of which is aircushion belt conveyor in recent years. However, our level is lower than foreign advanced level in design of belt conveyor, manufacture and application while there is much space in domestic process of design and manufacture of belt conveyor. The design of the port coal belt conveyor represents the general process of design and has some reference value in future selection design.
