Guyson Corp. of USA: INDUSTRIAL PRESSURE-BLAST CABINET

Thursday, August 28, 2008

Guyson Corporation has introduced a more

compact and economical direct pressure media delivery module available on several sizes of

industrial manual cabinets. The Model 8-EP is the largest blast cabinet to be fitted with the

novel pressure-blast system.


Pressure-blast media delivery is preferred for processing of components with a large amount

of surface area and for surface treatment operations such as descaling, etching, coating

removal and surface preparation that may require greater kinetic energy. Because the Model

8-EP's direct pressure blasting system accelerates media throughout the length of the blast

hose, it is capable of delivering media particles at much higher velocities than suction-blast

equipment operated at the same blast pressure. The blast machinery manufacturer claims

that pressure-blast usually proves to be at least four times faster than suction-blast.


Consisting of a cyclonic separator linked to an A.S.M.E.-certified pressure vessel, the

pressure-blast module is attached to the rear of the blast cabinet. The standard pressure

vessel holds approximately 0.8 cubic foot (22.6 liters) of media.The separator/media

reclaimer removes dust from the recirculated blast media and is powered by a freestanding

cartridge-type dust collector with an air extraction capacity of 500 cubic feet per minute (14

m3/min.). Flexible ducting connects the dust collector to the cyclonic separator, allowing the

collector to be positioned wherever it is most convenient.


The blast chamber of the Model 8-EP is 36 inches high at the rear of the sloped cabinet,

42 inches wide and 42 inches deep (914 H x 1066 W x 1066 mm D). Open access to the

finishing chamber is provided by side- and top-hinged doors at the front, to simplify loading of

bulky work pieces, as well as a convenient side-hinged, slam-shut door on one side. The

cabinet is optionally equipped with a 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.


Most types of dry blast media can be used in the Model 8-EP pressure-blast cabinet,

including plastic grit, glass beads and fast-cutting mineral grit, such as aluminum oxide,

giving the system great versatility for a wide range of blasting applications. When harsh

abrasive media are to be used, 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.
