Roller conveyors the shot blasting cabinet is manufactured completely from manganese. 

Therefore manganese has extremely good blasting properties. In the hot spot area of the blasting cabinet, additional 10mm thick manganese plates are added. They are attached from the outside and are easy to replace. When aggressive shot is used, additional lining of manganese-, tool steel or cast material can be provided.

To avoid shot leakage, several rubber layers are fitted in areas of heavy wear. These are mounted in a V-Track and are easy to replace.

Abrasive Removal Unit

After the blasting process, the workpiece may still be covered in blast media, which must be cleaned off. This task is carried out by a rotating brush, which is fitted with securely attached brush segments, which are interchangeable.

To avoid blast media building up on long parts, the rotation brushes flick the spent abrasive from the work surface into a specially designed trough which has a screw conveyor taking the media back into circulation. To keep the position between the brushes and the screw conveyor constant when blasting different sized work pieces, both are built with the same adjustable framework. The framework can be adjusted manually or automatically in intervals of less than 5mm at each required height. Finally any remaining media on the work pieces will be removed by the blow off station, which is mounted on the same framework and uses high pressure ventilators to blow off any media remaining.

Applications of Roller Conveyor Shot Blasting Machine

1.Marble & Cement: Stone surface roughness, anti-skid, retexturing, decoration;

2.Metal construction works: Cleaning surface for weld, cutting, drilling etc.  

3.Pipes: Suface cleaning for painting, coating or drilling, welding etc.

4.Plate: Finishing the sheet surface for painting, coating or cutting, weld etc.

5.Customized-made: Surfacing cleaning of rusting, rubber, sand etc.
