Shot-blasting Cabinet Has Dual Stations

Guyson Corp. has introduced a wide-body industrial pressure-blast cabinet with two work stations, each with a viewing window and independently adjustable blast nozzle.

The dual-station Model 7 shot-blasting system allows either two operators to blast simultaneously or one to change positions and reach all aspects of a five-foot-long component.

Dimensions and Features

The shot-blast chamber is 36 inches high, 60 inches wide, and 36 inches deep overall. A full-width, side-hinged door allows frontal access, with a slam-shut 19-by-19-inch door on the cabinet’s right side.

Additional height for loading tall components can be gained by raising the top-hinged upper section of the cabinet front.

All doors have safety interlocks that prevent operation of the blast machine until securely closed. Two sets of padded armholes have shoulder-length attached gloves.

How it Works

Stainless-steel shot is collected at the base of the blast cabinet and pneumatically conveyed up to a cyclone media reclaimer that separates dust and fines before feeding reusable shot to the pressure vessel, which has a capacity of 3.5 cubic feet.

The pressure pot automatically recharges with fresh shot whenever both foot pedals are released. Two metering valves at the bottom of the vessel enable control of the shot flow to each nozzle. The blasting pressure of each nozzle is also individually regulated.

Completing the system is a dust collector with an extraction capacity of 1,000 to 2,000 cubic feet of air per minute, which maintains negative pressure in the cabinet and balances the air flow to the media reclaimer.

An optional wet-dust collector is designed to collect potentially flammable dusts that may be generated when processing components made of titanium, magnesium or other reactive metals and their alloys.

Protection, Sample Testing

Abrasion-protection features designed to resist the harsh mechanical forces of shot-blasting include bonded rubber lining of the blast enclosure; cast urethane ducting to the reclaimer; lining of the cyclone inlet elbow, body and cone; and boron-carbide-lined blast nozzles.

Prospective users are encouraged to submit sample components for free laboratory testing and application engineering evaluation at the manufacturer's factory in New York State.
