Mar 22, 2017 (1rpm would move the belt at 1878mm/min which is too much, so we expect the required rpm to be 1rpm). The required velocity at the pitch diameter is 760mm/min so the required rpm of the conveyor sprocket is.. 760/1878 0.405 rpm The large driven sprocket is mounted on the same shaft as conveyor sprocket so it must also turn at 0.405 rpm.
Apr 09, 2015 The way to accurately find the speed of a conveyor is to measure the length then time it for 1 or several rotations. Make a mark Start on the belt, measure with a long tape measure to a second point, advance the conveyor then measure from point 2 to a new point 3, and so on until eventually you come back to start. This is the length.
(2)One VFD drive set as master, another one set as slave, because the belt conveyor is flexible connection, the master-slave motors can be controlled by speed. (3)The master drive receives the 4-20mA signal from weight sensor to calculate its output frequency, this frequency signal will output to slave AC drive as it frequency reference, to ...

Variable Frequency Drive for Food Conveyor. Nowadays the food machinery industry has been rapidly developed. As the motor drive, variable frequency drive will change the overall equipment level of food machinery to a certain extent. Effects of VFD is mainly reflected on the following two aspects increasing the output and reducing cost.
L conveyor length (m) belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note For long-distance conveyors, dynamic start-up calculations. may be required, because not all elements are set in motion simultaneously,
Mar 28, 2017 We have an Induction motor (7 KW, 400 V, 50 Hz, Delta, 15.5 A, P.F 0.75, 1465 RPM ) driving a conveyor belt. Motor is connected to the VFD ( ACS-800-01-0016-3, 8.1 KW, 3 X 400 VAC, 12 A, 50 Hz). Some values taken from the LCD of VFD at different times at different load

For example, if a conveyor operator reduces conveyor speed from 330 fpm to 165 fpm to move 450 tph of stone on a 120 ft. long x 36 in. wide inclined conveyor belt using a VFD (Figure 1), will the motor fail? Since required conveyor belt pull (Te) is 2,178 pounds to move the load at 330 fpm, then required power is 23.6 hp at that speed.
Jul 10, 2009 RobertL1. The best way to accomplish this is by using a Metering wheel controlled by a VFD or DC speed controller depending on the type of motor you use. A Metering wheel gives you the timing to separate packages being transported in a conveyor. The gap between packages is control by the speed of the metering wheel.
