Gibson Tumble Blasters process multiple parts, ranging in size from small to medium, with a level of speed and efficiency unmatched by other types of equipment in a comparable price range.

Gibson produces Tumble Blasters in seven standard models with load capacities ranging up to 3,000 pounds or 24 cubic feet. Our smaller units, available with either wheel or air-blast systems handle a broad spectrum of media and fit profitably into cell stations and other operations compatible with batch processing.

These rugged machines automate cleaning, peening, deburring, profiling, finishing and many other surface-conditioning tasks on a vast range of parts.

Plus they are simple to operate. The operator loads parts onto a rugged perforated belt, closes the loading door, sets the timer and pushes the start button. By tumbling parts within the blast envelope, these machines deliver consistent results automatically whether working intermittently or non-stop in a multi-shift production facility.

Applications: Batches of parts that can tumble on top of each other without causing damage to the parts.

Advantages: Can run large batches of smaller parts all together, nNo manual flipping or rotating, all sides will be blasted if they tumble properly.
