Calculate the Speed of Conveyor. Automation Control ...

09/04/2015  That means for each Hz of speed from the VFD, the load shaft moves .1Hz, and at 1m circumference, the conveyor speed will be 0.1m/second, x 60sec./minute = 6m/minute, x 60min./Hr = 360m/Hr = .36kM/Hr. So the factor to go from 1Hz to .36kM/hr is (.1 x 60 x 60)/1000 or .36, so if you enter .36 into A099, the display, and the output speed, will be in kM/Hr instead of Hz. You can then read

Belt Speed - vCalc

16/05/2014  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; RPM is the rotation rate (rpms) of the pulley; Simple Machine Calculators. Lever Beam Length ; Leverage Lift Weight ; Fulcrum Position ; Belt Length ; Belt Speed. Pulley RPMs ; 2nd Pulley RPMs; 2nd Pulley Diameter

Drives for conveyors in mining Danfoss

Smoothly controlling the acceleration and deceleration of long conveyors reduces mechanical stress throughout all drive-train components and within the conveyor belt itself. This leads to longer lifetime for the belt and other drive components, increasing asset availability and lowering maintenance and operating costs. Having the flexibility to control the speed of long conveyors can help optimize the
