  • Abrasive grit material recovery system
    Patent number: 5622265
    Abstract: A mobile apparatus and process for the separation and recovery of abrasive grit material from blasting material containing waste material and contaminants. The mobile apparatus has a low profile which facilitates the movement of the apparatus to job sites. At the job site the blasting material is collected by the mobile apparatus through a flexible hose connected to a chamber which is under sub atmospheric pressure. A vacuum generator that reduces the pressure in the chamber has sufficient power to allow vacuum collection of the blasting material through the flexible hose when material flow might otherwise clog the hose. The abrasive grit material is removed from the blasting material by a self-contained, multi-step separation process situated within the chamber. The mobile apparatus utilizes an initial physical separator, a rotary screen separator, a magnetic separator, and an air wash separation device that are interconnected by a rotary lift wheel.
