The Pangborn Heavy Duty GN Barrel Blast Machines (Metal Belt) is exclusively designed to thoroughly clean all types of castings, forgings, weldments, heat-treated work, and stampings. Our barrel blast machines are designed to process a variety of work pieces that can be tumbled, and the endless conveyor belt and lateral round place creates a trough in which work pieces are treated.

Available on back-order

Pangborn Heavy Duty GN Barrel Blast Machines (Metal Belt) tumbling action, provided by the endless rubber or metal internal conveyor, ensures all surfaces of the work piece are cleaned in one loading.

Highly configurable, these machines can be delivered with a rubber or metal conveyor, vibratory conveyor, magnetic separator, hydraulic loader, unloading conveyor, and dust collector.

The loading and unloading process is specifically geared to the work piece and workspace requirements. The optimum adjustment of the blast capacity is specified to the required blasting result. The tumbling action provided by the rubber or metal conveyor ensures that all surfaces of the work piece are cleaned in a single batch.

Pangborn offers a variety of barrel sizes depending on the size of the work pieces being blasted. Most often, larger machines are used for high output cleaning on medium sized castings, forgings, or fabricated work pieces. Barrel Blast Machines allow for a high volume of work pieces to be processed in a small working area.
