Process | Kildare Shotblasting and Priming LTD

Initially, the workpieces are conveyed along the inlet roller conveyor into the shot blasting chamber. Once shot blasting is complete, the workpieces proceed into the clean chamber where they undergo cleaning to remove blasting media and contaminants using brushes, a reclaim screw conveyor, and a high-pressure fan.

After the cleaning process, a coating is applied in the spray chamber, and the finished workpieces are then transported into the drying chamber. A slat conveyor facilitates the movement of the parts towards the outlet roller table. At this stage, they are either removed from the line or fed into a downstream logistics system via the cross-transfer conveyor.

Transport Systems

The sransport systems allows us to leverage heavy machinery to move full-length steel in and out of the unit at ease. Using a roller automatic conveyor lines we can move the steel from the langing are all the way to the finished product without handling it again.

Shot blast systems

The roller conveyor shot blast systems play a crucial role in the complete shot blasting and primer coating line. Components such as large steel sheets, tubes, round bars, angle bars, and I-beams are transported on a roller conveyor through several stages including the pre-heater chamber, blast chamber, and a blow-off/brush-off station.

Mounted onto the machine housing, the high-performance blast wheels ensure thorough and consistent blast coverage of the parts. This process optimally prepares the surface of the parts for the subsequent primer coating, ensuring effective corrosion protection and enhancing the overall quality of the finished products.

Paint Spray Chamber

The paint spray chamber automatically identifies the various plate and profile widths, applying a continuous coating process with a weld-primer thickness ranging from approximately 15 to 25 micrometers (μm).

To address environmental concerns, paint dust and solvents (if non-water-based paint is utilized) undergo treatment in accordance with local regulations. This treatment typically involves passing them through an automatic filter unit and a paint mist treatment plant.

Drying chamber & slat conveyor

In this area, the preserved steel plates and profiles undergo continuous drying. Workpieces are conveyed through the drying chamber using a slat conveyor. To minimize contamination from overspray, there is a considerable distance between the spray zone and the slat conveyor. Additionally, an elevating roller is strategically positioned upstream to address height discrepancies and ensure smooth transfer of thin plates onto the conveyor cross slats, thus preventing bending. The plates are supported only by the contact points of the conveyor cross slats, minimizing contact with the workpiece and preserving the wet primer.

The length of the drying chamber varies based on factors such as the type of paint, coating thickness, and passage speed.
