Abstract: Based on the belt conveyor starting and stopping are described, the rigid starting of belt conveyor tension analysis and rigid brake condition belt conveyor stress analysis, illustrates the belt conveyor soft start advantages. The belt conveyor of several soft starting modes are compared.
Belt conveyor soft start refers to the drive motor starting, through some device or set, so that the belt conveyor operating speed from zero degree controllable smooth transition to the theory of running velocity of a starting mode. Common soft starting mode : motor + torque-limiting type hydraulic coupler + reducer flexible connection mode; motor + reducer variable speed hydraulic coupling + flexible connection mode; CST (Rockwell American Dodge company ) and controllable starting mode. The
Ann Jialing open-pit coal mine in Pingshuo Coal Preparation Plant is a year into wash capacity of 15000000 t oversize coal preparation plant, using belt conveyor number is more, large transport capacity, long distance transport, the maximum width can reach 2200mm, transport the largest reach 5000t / h, for such a belt conveyor, previously encountered less, must from the theory of belt conveyor running condition, stress condition of such detailed analysis, to ensure its stability, reliability, economy. The
One, belt conveyor starting and parking status description
Belt conveyor starting and stopping, if want to ensure material in tape without slipping, starting material and adhesive friction F 2 and material along the tape direction of gravity force F 1 difference is equal to or greater than the starting of belt conveyor dynamic load of 1 mA to ask, when stopping material and adhesive tape the frictional force of 2 F and material along the tape direction of gravity force F 1 and should be greater than or equal to 2 Ma starting dynamic load requirements, namely: we meet
