Specifications

It is suitable for de-sanding, de-rusting, de-scaling and surface hardening of the small work pieces

I. Applications and Features

 

This machine uses high-speed revolving impeller to throw abrasive onto the continuously tumbling work pieces in barrel, to attain the cleaning purpose. It is suitable for de-sanding, de-rusting, de-scaling and surface hardening of the small work pieces, such as castings, forgings, impact extruded-parts, gears, springs, etc., in various industries.

Note:

 

This machine is a newly designed product that integrates domestic and foreign techniques, so it is a kind of equipment with good cleaning effect, compact structure and low noise emission, it can be easily integrated into existing production line.

Following features:

1,  The machine adopts cantilever-centrifugal blast wheel with long life long and simple structure.

2,  The machine adopts BE type separator with good separating effect and high productivity, and it plays positive role in lengthening the lives of blades.

3,  The machine adopts bag type dust collector to make the dust density in the exhausted air lower than that stipulated in national standard, to improve working environment.

4,  The machine adopts wear-resistant rubber apron belt, to decrease collision and damage to work pieces and reduce noise.

5,  After cleaning, the parts can be unloaded automatically, so reduces the labor intensity. 

 

II. Main construction and working principle

   This machine is small-scale cleaning equipment, and it is mainly consisted of cabinet, blast wheel assembly, elevator, separator, electric system and so on, see Fig 1 (Table 1 shows all Codes and relevant Names). 

The working principle:

 

Putting stimulated amount of work pieces in the cabinet. After the machine start, the work pieces are overturned by the moving apron belt, meanwhile, the abrasive, be shot off rapidly, shapes shot-beams and hits evenly on the surface of the work piece, to clean them. The abrasive and sand projected flows into the bottom-sifter through many holes on the apron belt, then it is transported into elevator by screw conveyer and finally into separator to separate. The dust, comes from cabinet and separator, is filtered in the dust collector, and fresh air is let out. The dust attached on the bag is mechanically shaken-off and falls in the dust box at the bottom of the dust collector, so user may clean it periodically. The used sand flows out through the waste pipe, and can be reclaimed. The mixture of shot and sand is taken back into the cabinet, and may be reused after being separated. The clean abrasive flows into the blast wheel to hit work pieces through the electromagnetic shot valve.
