ROVAN recovery sand blasting machine uses compressed air as power to spray abrasives to the workpiece surface at a high speed. After abrasive impact, the workpiece surface dirt and rust are removed, so that the surface reaches a certain cleanliness and roughness. The sand and dust are recovered by negative pressure generated by vacuum pump or multistage vacuum generator, and the complete abrasives are separated and recycled through the sand and dust separation system of the equipment. Dust and rust enter the dust collecting bucket. It can be widely used in ships, Bridges, water conservancy engineering, mining, petroleum, chemical industry, metallurgy, paper making, port construction, aircraft vehicle manufacturing and other fields.
