Apron feeders Figure1E shows the apron feeder. The apron feeder is used for dealing with materials which are very hard, abrasive, tough and for lumps of larger dimensions; which are beyond the scope of belt feeders. The boulders of even m edge length dimension can be handled, because such lumps will be falling and carried by steel pans,

Apron Feeders are generally used as a primary or bin feeder appliion designed for varying appliions, from lightduty to severeduty, from low tonnage to high tonnage of material. They are the feeder of choice for reliability, high uptime and high returns on .

23/11/2006 · 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.

Apron Feeder. apron feeder heavy duty primary feeder Designed for mine sites and primary quarry appliions involving severe material weight, impact and abrasion, Rocktec has versions to suit all. The overlapping pans are bolted to crawler tractor chain and driven by segmented sprockets.

08/07/2019 · Normally, the optimal speed an apron feeder is – m/second (10–80 fpm). If the ores are nonabrasive, the speed can increase to above 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 ...
