Horizontal Blast Machine is a cost-effective and environmentally method for preparing concrete and steel surfaces. The machine is designed to remove paint strip from 200 to 1200mm wide and to be dust free. Walk-behind shot blasting systems use a high performance, airless, centrifugal wheel for propelling blast media at a high velocity, in a controlled pattern and direction. Ride-on systems use a paddle wheel configuration. In both types, metal abrasive, thrown by the rapidly rotating blast wheel, is accelerated towards the surface being prepared. The media strikes the surface and rebounds along with removed contaminants into a recovery chamber (separator). The dust collector removes pulverized abrasive, dust and contaminants. Very little abrasive is lost and the usable media is returned to the storage hopper for recirculation by the blast wheel.
