Shot blasting pass‑through unit for cleaning sheet metal and shaped blanks (model DPU(PCh) 1.0×0.8‑4)
It is designed for high-performance abrasive cleaning of metal products from various types of surface contaminants: rust, scale, welding deposits and oxidation products.
Main advantages and functions:
- Uniform processing: During the cycle, the products rotate vertically, which ensures that all surfaces are cleaned.
- Surface hardening (riveting): It forms a system of residual compressive stresses, significantly increasing the fatigue strength and wear resistance of parts.
- Improved adhesion: Prepares the surface for subsequent high-quality painting.
- Environmental friendliness and safety: The modern dust filtration system completely eliminates emissions into the work area and the environment.
The sequence of the processing process:
- Loading: The product is fixed on a conveyor suspension with a rotating system and fed into a closed working chamber. (The entrance portal is protected by curtains made of wear-resistant rubber).
- Processing: The rotation cycle starts. Throwing devices feed the shot directionally at an adjustable angle.
- Abrasive recycling: The spent shot is fed through a collection funnel to a screw conveyor (auger), then a bucket elevator (noria) transports it to the separation system. There, the whole fraction is separated from the contamination, accumulates in the hopper and returns to the throwers through the metering valve.
- Unloading: After the set time has elapsed, the process stops automatically and the finished product is removed from the chamber.
Automation: The high level of automation of the installation guarantees stable cleaning quality and minimizes fraction consumption.
