Apron feeders are available in a wide variety of designs for both horizontal and inclined travel. They help in feeding of material at controlled and continuous flow rates. These are mainly used to handle large sized lumps.
The typical design is a series of pans mounted between two strands of roller chain, with pans overlapping to eliminate dribble, and often equipped with end plates for deeper loads. Pan design may vary according to material requirements.
Apron-feeder applications range from fairly light-duty applications with light-gauge steel pans up to extremely heavy-duty applications requiring reinforced manganese steel pans with center supports.
