Conveyor and feeder have many various type such as belt conveyor, screw conveyor, apron feeder. Then comes detailed information about screw conveyor and apron feeder.
First to say is the aspect of conveyor. Transport capacity is an important indicator of measuring the capability of screw conveyor. The transport capacity could be calculated through the following formulas: Q=47D²S.n.ψ Q——transport capacity (t/h) S——pitch,m D——diameter of screw blade (m) N——speed of spindle (γ/min) Take-up device is one of the conveyor components. Take-up device includes screw take-up device, gravity take-up device, jinny take-up device, automatic tensioning device. Each has its own advantages and disadvantages. They could be respectively applied in different belt conveyors. Second to say is the principle of apron feeder The apron feeder adopts high-duty bulldozer's die forging chain (pitch of 228.6mm)as traction. Two chains circles a pair of drive sprocket in machine head and tightening pulley in machine tail to form closed loop circuit. The fitting of conveyor trough in each chain unit of two chains makes the apron feeder form a continuous conveying line. The self-weight and materials weight are supported by rows of track roller, jockey pulley, track beam. The drive system operates through the connection of ac variable frequency speeding motor and reducer, connection of casing and transmission. The apron feeder conveys materials from stock bin along the conveyor line to the front of engine, which realizes the purpose of downward continuously uniform feeding. That is all in this blog, I will renew my blog regularly~ Hope you could kindly read my articles. In the end, hope everyone have a good day!
