Product Description
Shot Blasting and Priming Machine combine the blasting, coating and drying of workpieces such as sheet steel, profiles, pipes or steel structures in one automatic line.
The shot blasting and priming machines are ideal when there is a lengthy manufacturing or storage time between blasting and final coating. In order to prevent rust returning, a weld primer is applied to provide corrosion resistance for weeks.
Sheet widths of up to 5000mm can be processed, with passage speeds varying from 1.0m/min to 5.0m/min.
Blasting chamber
Blasting chamber liner is manufactured completely from high manganese. High manganese has a property which is hard enough to deal with the shot blasting from 35HRC to more than 60HRC. They are attached from the outside and are easy to replace. When aggressive shot is used, additional lining of high manganese, tool steel or cast material can be provided. To avoid shot leakage, several rubber layers or curtains are fitted in areas of heavy wear. These are mounted in a V-Track and are easy to replace.
Abrasive cleaning up
To avoid blast media building upon long parts, the rotation brushes remove the spent abrasive from the workpieces surface into a specially designed trough that 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. 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.
Spray room
After shot blasting the metal roll goes to painting booth. The painting equipment provides the coating thickness 15-20 micron.
To avoid the raw paint damage the metal roll is transferred by the chain conveyor with bearing elements. It provides minimal contact with painted surface. The paint that couldn't reach the product is taken with air flow and directed to labyrinth filters. The filtered exhaust air is emitted to the atmosphere.
Drying room
The primer drying chamber works in recycling mode: the heated air is fed from the preliminary drying chamber with 10-15% fresh air intake from "outdoors" to prevent the recycling air oversaturation with solvents. The temperature from 30 С to 80 С is set according from primer type. As well as in painting booth, the transportation is made by chain conveyor with bearing elements. It guarantees minimal contact of painted surface with conveyor surface, protecting the painted surface from damage.
