MoreMay 27, 2008 I build a lot of conveyors using 89 dia rollers, for handling pallets various line speeds are used but just for example, with your load, say 7.5 metres per minute conveyor speed will only require about 0.3 kw to drive.

MoreThe following formula is used to calculate load torque for belt drives (conveyors) as well as rack and pinion drives. For this type of application, we'll need to calculate force ( F ) first before we can calculate the load torque ( TL ).

MoreIn order to find the maximum tension is necessary to calculate the effective tension, that is, the force required to move the conveyor and the load at a constant speed. The calculation of the total tension is based on a constant speed of the belt including the necessary basic conditions to overcome the frictional resistance and tension forces.

MoreMay 16, 2014 Belt Speed (BS): The calculator computes the belt speed (BS) in meters per second. However, this can be automatically converted to other velocity units via the pull-down menu. The Math. The formula for the speed of the belt is: BS = (D •π • R)/(2π) = ½•D•RPM. where: BS is the Belt Speed; D is the diameter of the pulley
