Study on the Roll Feeder for Moving Beds

Abstract

The results of experimental study on characteristics of a roll feeder for moving beds are as follows :
(1) The discharge rate is in proportion to the revolving speed of the roller and is not in proportions to height of the slit.
(2) To reduce the crush and abrasion of particles, the height of the slit is required to open more than a limit for mechanical blockage of particles.
(3) Installation of a moderate rectification part between the moving bed and the discharger is preferable to form a uniform particles flow in the bed.
