Apron feeders: the material handling workhorses

2019-10-3  The resistance to shear the material is typically estimated to be between 50-70% of the total force/power. This calculation of the shear length will result in either insufficient power (lost production) or excessive power (rising operating expenses (opex)).

Bulk Handling Technologies Australia Apron Belt

Unlike a belt feeder where the take-up is required to provide additional tension so that the belt can transfer the force into the head pulley using friction, the apron belt feeder only requires the take-up to reduce the sag between return rollers. Therefore the relative take-up forces required are much lower when compared to belt feeders.

Apron feeders: the material handling workhorses

2019-10-3  So why is bulk density so important? Apron feeders are volumetric-type feeders, which means bulk density is used to determine the speed and power needed to extract a certain tonnage per hour of the material. The minimum bulk density is used to determine the speed, and the maximum bulk density establishes the power (torque) needed for the feeder.
