Apron Feeder Calculations - bulk-online

Nov 23, 2006 · 6) Apron feeders always need variable speed drive. So, maximum of variable speed range should correspond to design capacity, which could be about 20% more than the guaranteed capacity. That means apron feeder will normally run below maximum range by certain margin. This provides room for selection of speed during field trials / setting.

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.

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 ...
