29. It consists of a series of overlapping Heavy Duty Pans (or Flights) that
carry the material.
Used for handling more abrasive, heavy and lumpy material. The
material is carried on an overlapping metal plate called pans, which is
mounted between strands of the conveyor chain.
Apron feeders are placed under storage bin for regulating the feed
material
30.
31. An Apron Feeder can regulate the flow of material based on
volume. The pan speed and the gate cut off height can be regulated to
provide an even volumetric feed down stream.
.
32. A short belt conveyor. The belt is flat and supported on closely spaced
idlers or on a smooth slide plate.
Belt feeders are used for handling fine / free flowing / abrasive
materials. Even properly designed belt feeders are used for handling
lumpy material.
Increased redundancy and flexibility
