storage bins. Apron feeders have capacities up to 6000 t/h and are able to transport materials with maximum lump size up to 2000 mm. The large size of material lumps is the cause for the increase of the width of the aprons and the height of the skirts. The presence of fixed skirts causes additional resistances due to skirt friction. The presence of
Apron feeders are a reliable solution for extracting or feeding ores that are wet, sticky, dry or even frozen. Liming apron feeder's diversity can be found throughout the mineral processing circuit fitting different applications with robust designs and high uptime for a more efficient operation.

How to Design Efficient and Reliable Feeders for Bulk Solids by John W. Carson, Ph.D. and Greg Petro, P.E. A feeder is an extremely important element in a bulk material handling system, since it is the means by which the rate of solids flow from a bin or hopper is controlled. When a feeder stops, solids flow should cease. When a
