Variable-Speed Belts
A wide profile allows these belts to ride up and down the groove in variable-speed pulleys to handle a wide range of speed ratios. Notches increase flexibility for bending around small-diameter pulleys and dissipate heat for a long service life.. For technical drawings and 3-D models, click on a part number.
Sizing a Screw Conveyor
— The speed should be under the published maximum speed (RPM) but in most cases 40RPM – 80RPM is a good range. There are published max speeds for different diameter screw conveyors but these speeds tend to be much higher than is recommended for a long and reliable screw conveyor service for almost all applications except feed and …

Selecting the Optimal Conveyor Drive
— There is a strong trend for variable speed fixed conveyors to be driven by a three-phase AC motor working with a variable frequency drive (VFD.) The use of DC motors to drive variable speed belt conveyors is declining because of the lower motor and control cost and high reliability of the AC motor/VFD concept. See figure 13.
Chain Conveyors
If the calculated speed "v" is greater than the limit speed for aprons, the skirt height "h" must be increased. The drives allow variation of the speed to match, which is v = 0.03 m/s – 0.16 m/s (0.1 – 0.5 ft/s). For different capacities, can be used variable speed DC, AC and hydraulic motors.
