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

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 ...
