Portable shot Blasting Machine is a cost-effective and environmentally method for preparing concrete and steel surfaces. 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. The concrete dust is recovered by a powerful dust collection system. The machine is designed to remove paint strip from 200 to 1200mm wide and to be dust free. 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.
