Guyson Corp. (www.guyson.com) added two direct drive blast turbines to its Model GWB-70WL rotary table wheel-blast system so that all surfaces of three-dimensional components get complete coverage from the cleaning or finishing media. The 70-in.-diameter turntable has replaceable plates that are cast in abrasion-resistant alloy. The same alloy is used for all interior surfaces that are exposed to media blast. The gear drive rotary table has a weight capacity of 4,000 pounds.
