The belt feeder is composed of a conveyor belt which is supported by rollers. The length can vary from 1.5 to 3 m and speed from 0.005 to 0.5 m/s. Power requirements vary from 3 to 30 hp.
This feeder type is ideal for close volume control of sand and gravel, and especially for dry and fine materials. It has a simple and cheap structure, easy to adjust. The power requirement is low power, and the volume can be controlled within 1% from a remote station and with over-riding tie-in to any load.
