Sep 17, 2019 · Apron feeders are a volumetric type feeder, which means bulk density is used to determine the speed and power (torque) needed to extract a certain tonnage per hour (tph) of material. The minimum bulk density is used to determine the speed and the maximum bulk density establishes the power (torque) needed for the feeder.

## Feeding the facts 1/3: Apron feeder basics - Outotec

Jul 08, 2019 · Normally, the optimal speed an apron feeder is 0.05 – 0.40 m/second (10–80 fpm). If the ores are non-abrasive, the speed can increase to above 0.30 m/second because there will be less wear. Higher speeds would hurt an operation. If your speed is too high, you run the risk of accelerated wear of components. Energy efficiency decreases due to ...
