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.
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.

— Variable speed drives allow variations in material flow rates. Behavior, Control, and Environment. Product mobility, control, and the placement of a roller conveyor are additional critical factors that are examined when designing a roller conveyor. The function of a roller conveyor can be affected by heat, dust, dirt, and moisture, which may ...
— A variable speed drive on large primary semi-autogenous mills can overcome this problem to a considerable degree. A major disadvantage of large semiautogenous mills has been the necessity to keep the mills fully loaded at all times to minimize ball and …
Lubricate the conveyor regularly to ensure smooth movement. Replace any worn-out parts promptly to prevent further damage. When dealing with cohesive materials, take extra precautions to prevent clogging or uneven movement. Consider implementing mitigation strategies such as using anti-clogging devices or adjusting the conveyor speed.
— Therefore, stepper motors are recommended for positioning applications with a limited duty cycle, such as in indexing conveyors, and brushless motors, designed to run continuously, are a better match for continuous running variable-speed conveyors. The table below summarizes the differences between AC motors, brushless motors, and …
