Drive Pulleys. What is a drive pulley? You may have guessed it by the name, but drive pulleys are in fact the driving force of a pulley system. The drive pulley connects to the power source, which could be the shaft of an electric motor, or even a hand crank. In turn, the drive pulley then applies a force onto the belt, which causes it to move.

Motor-Drive sizing. To effectively size the motor, it is necessary to calculate the load inertia (JL). The ratio of load inertia to motor inertia (essentially, rotor inertia) gives a measure of how effectively the motor can control the load. A high inertia ratio indicates the system that will have difficulty controlling the load.

A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage …

Pulley and Belt Length Calculator. In this calculator, there are three main sections dealing with pulleys, belts and speed. In each section, only one variable is calculated, based on the checkbox. In the first, the driver pulley is the powered (usually by an electric motor) pulley. The driven pulley is the reactive pulley to the driver.

Motors and Controllers: >NOTE: All motors and controllers require regular 110v AC electricity!! (International 220v and 3 phase input is available by special order) After selecting the style motor mount we need to size the proper motor to drive the number of fans in the system. All of the motors listed fit both of the motor mounts described above.

The power input required to maintain this condition is theoretically: hp = (W) (C) (Sin a) (2π) (N) 33.000. where W = weight of charge. C = distance of center of gravity or charge from center of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in rpm. The value of the angle a varies with the type of discharge, percent of ...
