A steel service center in a certain location in Vietnam was expanding its processing capacity. The company received hot-rolled steel plates up to 2.5 meters wide and 12 meters long. These plates required surface cleaning to remove mill scale and rust before painting. Their existing small cabinet blaster was too slow and could not handle plates longer than 3 meters. Manual grinding was labor‑intensive and left uneven results.
The production manager needed an automated solution that could process long plates continuously. After researching online, he discovered YG’s roller shot blasting machine. He wanted a pass-through shot blasting machine that could handle 2.5m wide plates and integrate with his existing roller conveyor system. YG recommended the YG‑6925 model.


Technical Parameters Of The Roller Shot Blasting Machine
YG offers eight models of the machine. Based on the customer’s maximum plate width (2.5m) and thickness range (3‑60mm), YG selected the YG‑6925. Below are key specifications:
| Parameter | YG-6925 Value |
| Effective cleaning width | 2500 mm |
| Room feed-in size | 2700×800 mm |
| Workpiece length range | 3000-12000 mm |
| Conveyor speed | 0.5-4 m/min |
| Steel sheet thickness range | 3-60 mm |
| Section steel specification | 2500×700 mm |
| Shot blasting quantity | 6×250 kg/min |
| Total power | 204.8 kW |
| Airness size | 27758 m³/h |
The roller shot blasting machine uses six shot blasting wheels, each delivering 250 kg/min of abrasive. This machine features a variable‑speed conveyor for adjusting cleaning intensity.
How This Conveyor Type Shot Blasting Machine Transformed Production
The Vietnamese service center installed the machine at the end of their plate shear line. The first test was on a 10m long, 20mm thick plate. Results were immediate:
- Cleaning speed: The roller shot blasting machine processed the plate in under 5 minutes, achieving a Sa 2.5 surface finish.
- Uniformity: The six wheels covered the entire plate width, eliminating missed spots.
- Integration: The pass-through shot blasting machine connected seamlessly to the existing roller conveyor, allowing one‑person operation.
The conveyor type shot blasting machine also handled section steel and beams. The operator adjusted the conveyor speed from 0.5 to 2 m/min depending on the material thickness.


Customization For Vietnamese Conditions
YG engineers considered Vietnam’s hot, humid climate and the customer’s power supply limitations. Customizations included:
- Motor insulation upgrade to handle 45°C ambient temperatures.
- Voltage stabilizer to protect against fluctuations in the local grid.
- Dust collection system with extra filter bags for the high‑humidity environment.
- Anti‑corrosion coating on all exposed steel parts to resist rust.
For the roller shot blasting machine, YG also provided Vietnamese‑language control labels and an operation manual. The pass-through shot blasting machine was shipped with a starter set of wear parts, including blades and control cages.
Tangible Results After Using The Roller Shot Blasting Machine
After two months of operation (8 hours/day, 6 days/week), the Vietnamese service center recorded measurable gains:
- Cleaning output increased from 5 to 35 plates per day.
- Labor cost dropped by 70% – one operator now handles the entire process.
- Surface quality improved consistently to Sa 2.5, meeting international standards.
- The reject rate due to insufficient cleaning fell from 12% to under 1%.
The roller shot blasting machine paid for itself in eight months. The service center has since ordered a YG‑6930 model for processing wider plates up to 3 meters.


Smooth Cooperation And Final Conversion
YG provided 3D layout drawings and foundation requirements. Sea freight was arranged from China to Ho Chi Minh City port, then trucked to the facility. Remote video support via WhatsApp guided the electrical connection and wheel alignment. The roller shot blasting machine came with a one‑year warranty and a spare parts list.
