Description
Application
The RB‐600 AH 4 wire mesh shot‐blasting machine is mainly suitable for the low
investment cost de‐rusting, de‐scaling and cleaning of
Small castings made of aluminium or steel
Small forged parts made of aluminium or steel
All smaller parts that cannot be bulk blasted
Description
The machine is equipped with 4 pieces of ABR 380 type blasting turbines. 2 of these
turbines is situated above the wire mesh conveyor top level and the rest of the
turbines are placed under it to ensure the possible best covering of the through‐pass
cross section. Blasting is done in an angle of ~70° to the direction of proceeding to
reach lengthened covering.
The turbines are gravity fed with abrasive material, they have eight blasting blades
and a pre‐accelerator and they allow precise blasting direction adjustment.
The inner surfaces of the machine in the active zone are covered with highly wear‐
resistant manganese steel, other inner parts are protected by wear‐resistant rubber
sheet. This rubber cover has noise‐reducing effect as well. wires in the machine hou‐
se are made of highly wear resistant spring steel to provide suitable lifetime for the
conveyor.
The three‐layer rubber curtains at the inlet and outlet sluice prevent the high velocity
abrasive particles from shooting out.
The closed and continuous circulation of the shot‐blasting media is ensured by a screw conveyor, bucket elevator, abrasive cleaning air classifier unit and a feeding unit. In foundries an additional magnetic drum separator is built in the machine to separate forming sand from the circulation.
The clean work‐piece is de‐dusted by a high pressure blow‐off fan built on the exit section of
the machine with adjustable height.
The dust‐aspirating and separating system of the equipment consists of galvanized steel air‐ducts, form‐elements, aspiration fan and filter cartridge inserted dust‐separator.
Dust emission after the filter is not more than 3mg/m3.
