The Vertical Shaft Impact (VSI), also called Sand-making machine, is widely used to process the stones into sands. Anvils and Impellers are the main wear parts on this machine. As the processed stones are always very hard with a high content of silicon, the wear parts are withstanding severe wearing during the crushing process. VIBO make the both parts with ceramic inserts at the weak areas to prolong the wear life of parts to reduce the downtime of machine.
