It is designed to clean various surfaces from corrosion products, old paint, scale, oil, lubricants, and other foreign substances, leaving ideal surface for the application of protective anticorrosion coating.
AREA OF APPLICATION
It is used for abrasive blasting works at construction sites, for repair or building of road and railway bridges, at oil refineries, tank storage farms of oil, shipbuilding and ship repair yards.
Supplied with Sandsturm® multipurpose abrasive metering valves, which allow working with any common abrasives 0,1 to 4 mm grade: cast-iron and steel shot and grit, marble and granite chips, glass beads, aluminum oxide, silicon carbide, alundum, copper and nickel slag and other kinds of media fabricated specially for blasting.
Its work is performed by means of introduction of abrasive material through the abrasive metering valve SANDSTURM®-P and compressed air through the air line into a pusher line assembly.
After mixing in the adjusted proportion abrasive-air mixture is supplied to the abrasive blasting hose at high pressure and is directed on to the surface that is being treated, passing through the abrasive blast nozzle and speeding up.
Couplings CLAMP allow you to take off the valve and discharge the abrasive from the blast machine in 5 seconds, remove the foreign object, which prevents the normal uninterrupted work, or replace the valve for its repair.
Bigger diameter inspection hatches for easy access to internal components.
A conical bottom has an angle of 90° providing the best discharge of abrasive material from the walls of the blast machine and prevents the absorption of moisture on the walls of the tank.
Silencer reduces level of discharge air noise during machine depressurizing and traps abrasive particles for safe operation.
They are equipped with high-efficiency air filter moisture separator MMS-32 for preventing of ingress of moisture, oil and other contaminants into the blast machine.
The sieve is located inside that reduces the overall height of the blast machine and makes it easier to load it with abrasive. A thick perforated metal sheet with openings of 4 mm is used as a sieve. A perforated sieve is more effective for screening abrasive material than a sieve made of wire mesh. It protects the blast machine from particles more than 4 mm diameter and different types of debris that prevent uninterrupted operation of the equipment. To protect the device, they use a lightweight metal edge-raised cover, the edges of which hang over the walls of the setting and prevents the passage of moisture into the machine.
