Belt Conveyor Drives Factors Selection 911
Conventional belt conveyors are powered by electric or electromechanical drives mounted at the conveyor’s head, tail, intermediate return span, or a combination of these The following are main elements influencing the selection of the drive system: MOTOR SELECTION for BELTCONVEYOR DRIVES Abstract—Rated power is the motor parameter always specified when motors are selected for a belt conveyor—motor slip is usually ignored This paper shows how the running and starting characteristics of a belt conveyor are influenced by slipMOTOR SELECTION for BELTCONVEYOR DRIVES The ideal location for the drive of a belt conveyor is the place which minimizes belt tensions both during the acceleration and running periods Although circumstances may dictate that a drive be located somewhere between the ends of a conveyor, locating it at the head end when the conveyor has to be powered to drive Conveyor Belt Drive Selection 911 MetallurgistMOTOR SELECTION for BELTCONVEYOR DRIVES Abstract—Rated power is the motor parameter always specified when motors are selected for a belt conveyor—motor slip is usually ignored This paper shows how the running and starting characteristics of a belt conveyor are influenced by slip It shows that highslip motors improve load sharing between [PDF] MOTOR SELECTION for BELTCONVEYOR Wedge Belt Selection Example Design a Wedge belt drive from a 90kW, 1440 rev/min direct on line start electric motor to a Belt Conveyor which carries copper ore and absorbs 81 kW The conveyor must run at 403 rev/min for 12 hours per day The required centre distance is 1200 mmBelts Drives Wedge belt selection procedure
