Abstract
A device for cleaning stock material, such as wire, rod, or tubing, comprises two separate blast chambers, each blast chamber adapted for receiving abrasive projected by two blast wheels. Each blast wheel creates a blast zone in the blast chamber through which the stock material passes. The blast zones are oriented to provide a surface treatment on all or a portion of the exterior surface of the stock material.
Claims12
A device for cleaning stock material, wherein the device comprises:
- (A) an enclosed first blast chamber for receiving abrasive projected by two blast wheels, wherein the first blast chamber has a stock material inlet for passage of stock material into the first blast chamber and a stock material outlet for discharge of treated stock material out of the first blast chamber;
- (B) an enclosed second blast chamber for receiving abrasive projected by two blast wheels, wherein the second blast chamber has a stock material inlet for receiving stock material from the stock material outlet of the first chamber, and a stock material outlet for discharge of treated stock material out of the second blast chamber;
- wherein each blast wheel projects abrasive in an abrasive pattern having a blast zone in the blast chamber such that a segment of the stock material simultaneously passes through each blast zone as the stock material traverses a linear path through each blast chamber;
- and
- wherein ¼ of the surface area of the stock material is treated by each blast wheel such that the whole surface area of the stock material is treated after the stock material passes through the first blast chamber and through the second blast chamber.

- wherein each blast wheel has throwing surfaces for projecting abrasive in an abrasive pattern having a blast zone in the blast chamber such that each blast zone is in the path of the stock material passing through each blast chamber, and wherein the throwing surfaces on the blast wheels do not face each other when abrasive is being projected by each wheel;
- and
- wherein ¼ of the surface area of the stock material is treated by each blast wheel such that the whole surface area of the stock material is treated after the stock material passes through the first blast chamber and through the second blast chamber.
