“With 5 years of operational reliability, since replacing our old tumble blast machine, we have saved our company over $225,000 and the Sinto drum blast machine had an ROI of under 2 years. Those kind of numbers are easy to sell to upper management.” -Tom Aument, Facilities and Maintenance Manager, Blackmer

Loading- Avoids breakage and damage to parts with smooth, reliable operations. It can be programmed to stop and start based on part configurations and ease of parts loading. Optional soft load capabilities distributes parts closer to the drum. Agitating and Cleaning- The systems core is a ware resistant magnesium drum available in 3 to 35 cubic foot volumes, supporting parts up to 90 lbs and 22 inches. The incredible durable of magnesium allows for a greatly increased working life. This process decreases cycle time over conventional steel belt and tumbling blast by as much as 50 percent and the maintenance cost saving alone are worthy upgrade from conventional steel belted tumble belt with no flights to replace, no chains to break, and no pins to ware out. Customers report up to 50% parts saving over the life of the machine. Unloading- With cycle complete, parts easily discharge from the drum into an automatic unload system.
