ABSTRACT:
A process and apparatus are provided for mechanically and pneumatically cning and stripping particulate granular and/or pulverulent solid materials which are particularly applicable to the regeneration of old foundry sand agglomerated by a binder. The particulate materials are introduced into and projected by a current of gas against the interior sides of a rotating drum where the materials are repeatedly subjected to a shock treatment.
