The characteristics of screw conveyor

Screw conveyor has following characteristics: Screw blade uses the design of variable pitch screw, which makes materials filling rate change from 100% to below 70%. At the same time, screw conveyor can stay the uniform acceleration motion of conveying materials, reduce the delivery resistance and prevent material from plugging and blocking. The screw pitch gap of screw blade at the bottom of feed ...

Receiving Scheme of Apron Feeder

The idea of feeding above the ground is suitable for movable receiving scheme proposed by users. In other words, on the conditions that fixed devices cannot meet the requirements, apron feeder could finish the receiving operation of general bulk materials(such as coal and aggregate) directly from dumper car of shipment devices. The operation of feeding above the ground leaves out the process o...

The principle of Conveyor Components

The coupler is one of conveyor components. The operating principle of fluid coupling is as follows: A certain amount of working liquid is injected into the working chamber of coupler. The pump impeller gets mechanical energy and then convert it to hydraulic energy. The hydraulic energy drives turbine to rotate, during which hydraulic energy changes into mechanical energy and the energy is ...
