Abstract

A device is claimed for the recovery of fine particle sepd. from materials of differing particle size being conveyed pneumatically into a hopper (2), in a system in which the original feed (3) is conveyed into a pre-fill chamber (6) which collects the material and which exhausts the conveying fluid plus any entrained fine particles via an outlet hose, the prefill chamber (6) dumping the solid material at appropriate interval into the main hopper (7). The recovery device comprises a line (12) leaving the prefill chamber and discharging (13) in the main hopper near the bottom of the material held therein, the carrier fluid rising with decreasing velocity through the bed of material in the main hopper before being exhausted (14) from the top of the main hopper.
