Pressure-blast cabinet delivers media particles at high velocities
- November 11, 2008
- Product Release
- Finishing
Guyson Corp. has introduced a compact, direct-pressure media delivery module available on several sizes of industrial manual cabinets. The 8-EP is the largest blast cabinet to be fitted with the pressure-blast system, the company states. The cabinet's direct-pressure blasting system accelerates media throughout the length of the blast hose. As a result, it is capable of delivering media particles at high velocities.
Comprising a cyclonic separator linked to an ASME-certified pressure vessel, the pressure-blast module is attached to the rear of the blast cabinet. The standard pressure vessel holds approximately 0.8 cu. ft. of media. The separator/media reclaimer, which removes dust from the recirculated blast media, is powered by a freestanding, cartridge-type dust collector with an air extraction capacity of 500 cu. ft. per min. Flexible ducting connects the dust collector to the cyclonic separator, allowing the collector to be positioned in the most convenient location.
The blast chamber of the cabinet is 36 in. high at the rear of the sloped cabinet, 42 in. wide, and 42 in. deep. Open access to the finishing chamber is provided by side- and top-hinged doors at the front, to simplify loading of bulky workpieces, as well as a side-hinged, slam-shut door on one side. The cabinet can be equipped with an optional rubber-flapped crane slot in the roof of the blast enclosure, above the side door, to facilitate loading and unloading of heavy components by an overhead hoist or crane.
The cabinet accommodates most types of dry blast media, including plastic grit; glass beads; and fast-cutting mineral grit, such as aluminum oxide. For applications that require the use of abrasive media, the cabinet is supplied with protective features that include rubber lining of the blast chamber; a wear-resistant, boron carbide blast nozzle; and a sacrificial inner abrasion window mounted in a quick-change frame to prevent accidental frosting of the safety glass viewing window.
Applications include descaling, etching, coating removal, and surface preparation.
