BELT CLEANER FOR REMOVING FINES FROM GRANULAR MATERIAL

摘要

A flow of the material is supplied to the inclined surface of a continuous looped belt. The surface of the belt is textured to form small pockets into which small particles fall and are held against downward motion as the belt is advanced up the incline. The larger particles in the material cascade down the belt and are collected for further processing. The small particles entrained in the pockets move up the incline with the belt and are removed from the belt when it reverses direction at the top of the incline. Fines removal is facilitated by an agitator which vibrates the belt as it reverses direction and moves down the incline. The size of the particles removed can be controlled by increasing the size of the pockets. The inclination can be varied to optimize the motion of the large particles down the inclined belt.
