📋 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
Liner is manufactured completely from high manganese, which is hard enough to deal with shot blasting from 35HRC to more than 60HRC. They are attached from the outside and are easy to replace. Several rubber layers or curtains are fitted in areas of heavy wear to avoid shot leakage.
Abrasive Cleaning Up
Rotation brushes remove spent abrasive from the workpiece surface into a specially designed trough with a screw conveyor. Remaining media is removed by a blow-off station using high-pressure ventilators.
Spray Room
The painting equipment provides a coating thickness of 15-20 micron. Workpieces are transferred by a chain conveyor with bearing elements to ensure minimal contact with the painted surface. Labyrinth filters capture overspray before air is emitted.
Drying Room
Works in recycling mode with heated air (30°C to 80°C). 10-15% fresh air intake prevents solvent oversaturation. Chain conveyors protect the painted surface from damage during transportation.
