Abstract

A pneumatic conveyance system for particulate material, particularly for reclaiming chemically bonded moulding sand from foundry moulds. The material is broken down and/or scrubbed during conveyance through the system which has a surface portion formed with peaks and depressions positioned in the path of flow of the material which break down and/or scrub the material as it strikes said surface portion.
