Tumble Blasts

Tumble blast machines gently tumble the parts to be cleaned in a blast chamber formed by an endless rubber mill belt. Parts are exposed to the blast stream as they tumble in the chamber.

Tumble blast machines offer a cost-effective solution for batch deburring, descaling and deflashing of metal castings, forgings, aluminum die castings and automotive parts.

Bronco Blast Equipment is heavy-duty and built to withstand the rigors of any manufacturing environment. Our machines are fully integrated blast systems that are designed for ease of operation, requiring minimal floor space.

Bronco tumble blast machines incorporate numerous safety and troubleshooting features to ensure safe and reliable operation.

Heavy-duty belts can handle the heaviest loads and our standard design assures a tight fitting blast chamber, allowing small parts (fasteners, etc.) to be cleaned that otherwise may jam or wedge in traditional steel conveyor belt machines.
