Tumbler Slurry Blasting Machine

Slurry blasting technology, also known as wet blasting, provides the ultimate parts cleaning performance within minutes. The system's innovative design uses a blast wheel to accelerate and discharge the abrasive slurry at high velocity and in a controlled pattern to mechanically remove oxides, scale, carbon deposits, oils, and grease from metal part surfaces. It can be applied safely to all types of metals and is excellent for use on aluminum and other white metal components. The abrasive slurry is composed of abrasive media combined with a hot waterbased alkali cleaning solution to provide a very clean and smooth finished surface ready for coating, painting, or remanufacturing operations.

before and after Slurry Blasting

Part surfaces are free of scale, oil, grease, and rust without any residue normally left by conventional blasting processes.

The Tumble Slurry Blaster is designed to automatically process batches of parts of various sizes loaded on the barrel work mill. The barrel mill tumbles the parts to expose all surfaces to the cleaning abrasive slurry. The entire process is automatically controled by PLC.
