There are many parts on the belt conveyor, generally includes a trapezium mill, transmission device, conveyor belt, a bracket, wherein, the tension apparatus is very important, it is directly related to the safe operation of conveyor can and is able to work a long time problem, then for the belt conveyor, the application principle of belt tension device is irreplaceable, in the actual production process, the belt tensioning degree requirements are very strict, so the requirement of trapezium mill is very high.

Generally speaking, the trapezium mill is mainly composed of a station, accumulator, cylinder, a control box and its accessories and so on, when the belt conveyor running, trapezium mill able to automatically adjust the tension of the belt, can at any time and place of balanced tension, and this kind of device can be conveyor belt tension is stable, dynamic the reaction is very fast, this is a kind of device is completely automatic programming, are respectively provided with manual and automatic two kinds of working mode, no matter what kind of mode will be able to guarantee the smooth operation of the belt conveyor. Through the above analysis we can know, no matter what kind of mode is conveyor, new type of belt trapezium mill can guarantee enough tension of conveyor belt, and the characteristics of unique can make the equipment suddenly elongation or contraction can be compensated, so visible tension device on the belt conveyor is the role of unparalleled.
