Guyson Corp.’s GWB-702T rotary table wheel-blast system features one blast wheel over each half of a 4,000-lb. capacity, 70-inch diameter turntable. It is said to be especially suitable for batch processing of workpieces that are flat or have limited vertical surfaces.

Each blast wheel is directly driven at a speed of 3,000 rpm by a 10-hp motor and is capable of throwing about 220 lbs. of metallic media per minute in an adjustable blast pattern as much as 36 inches long.

The machine table and the interior ceiling and walls of the blast chamber feature abrasion-resistant cast iron alloy plates. The inside of the blasting enclosure also is lined with thick rubber sheeting for abrasion protection, which also reduces sound levels during operation. A shot reclamation system with a tunable cascade airwash separator removes dust from the working media mix, and an adjustable cyclone separator captures and reuses good shot or grit that would otherwise be carried over to the dust collector. A freestanding Guyson D2000 cartridge-type dust collector with air extraction capacity of 2,000 cfm maintains negative pressure in the machine and balances the air flow through the media reclamation system.

A streamlined human-machine interface (HMI) replaces an array of separate switches, push buttons and indicators. The compact HMI includes prompts or text instructions related to fault indications and enables convenient direct entry of process parameters, such as blast cycle time or air wash blow-off cycle time, to the system’s programmable logic controller.
