Blast Tumbling Machines.

Wheelabrator offers a series of Super Tumblast machines for large castings not suited for the firm's Tumblast series of blast tumbling machines. Handling load capacities from 14-100 cu ft, the series provides a high-production means of processing large items and is ideal for scale and rust removal, sand removal, preparing surfaces for coating, grinding or machining, deflashing, deburring and shot peening. The heavy-duty machines are available with custom options to suit specific needs, including an abrasive adder system that alerts the operator when more abrasive is needed, eliminating the need for periodic abrasive checks and minimizing downtime associated with unnecessary maintenance. Other features include shaft-mounted direct drives that eliminate the need for belts, wheels and chains; a dual wheel package featuring 50-hp bi-directional wheel units; a clock dial control for accurate blast pattern adjustment; a manganese steel mill with a shaft-mounted gear motor in mill drive; abrasive reclaim system with hopper and lower reclaim system and replaceable abrasive-resistant screen; an abrasive separator with compensating flow design; and totally enclosed, pneumati cally operated abrasive control valves for noise reduction.
