1.3.1 Belt feeders Figure1D shows the belt feeder. The belt feeders are one of the widely used feeders. They are suited for handling of granular material or materials of comparatively lesser lump size (in comparison to apron feeder). The limitation of lump size depends upon toughness, hardness, abrasiveness and roughness of lumps.
