In the industrial province of Thailand, a steel service center was struggling to keep pace with surging demand. The facility supplied processed steel plates, beams, and structural sections to construction companies working on major infrastructure projects across the country—including sections of Thailand’s expanding rail network and new industrial estates. Their existing batch-type shot blasting equipment could only process a limited number of plates per shift. Each piece had to be loaded, blasted, and unloaded individually. The bottleneck was costing them contracts.
The operations director needed a continuous, high-throughput solution. After evaluating several options, he purchased a roller conveyor shot blasting machine from YG Machinery—specifically the YG-6920 model. This industrial shot blasting machine features a 2000mm effective cleaning width, a conveyor speed of 0.5-4 m/min, and the capacity to process steel sheets from 3mm to 60mm thick.
The difference was immediate. The Thai facility now feeds steel plates continuously through the machine, with rollers carrying each piece through the blast chamber for uniform surface preparation. Throughput tripled. The conveyor shot blasting machine paid for itself within eight months through increased production capacity and reduced labor costs.

Why the YG-6920 suited the Thai steel service center:
- 2000mm effective cleaning width – accommodated the widest steel plates the facility processed for infrastructure projects.
- 0.5-4 m/min variable conveyor speed – allowed adjustment for different plate thicknesses and surface conditions.
- 3-60mm thickness range – covered everything from light-gauge sheets to heavy structural plates.
- 6×250 kg/min shot blasting quantity – delivered powerful, consistent blasting across the full width.
- 19550 m³/h air volume ensured effective dust extraction and a clean working environment.
Three Challenges That Made Surface Preparation Difficult In Thailand
The Thai steel service center faced three problems common across Southeast Asia’s steel processing industry.
Problem 1: Slow Batch Processing
Traditional batch-type shot blasting machines require loading, blasting, and unloading each piece individually. With Thailand’s infrastructure boom driving demand for pre-processed steel, the facility could not keep up. Backlogs grew, and customers looked elsewhere.
Problem 2: Inconsistent Surface Quality
Manual loading and batch processing led to inconsistent blasting results. Some areas were over-blasted, others under-blasted. This affected coating adhesion and caused rework.
Problem 3: High Labor Costs
Each batch required operators to load and unload plates manually. With rising labor costs in Thailand’s industrial sector, the facility needed to reduce manual handling.
The roller conveyor shot blasting machine solved all three.
How The Conveyor Shot Blasting Machine Transformed The Thai Facility?
The YG-6920 machine is a continuous through-feed system. Steel workpieces—plates, beams, and structural sections—ride through the machine on motorized rollers. Inside the blast chamber, multiple spinning blast wheels throw steel abrasive at high velocity against every exposed surface, stripping away rust, mill scale, and welding slag. The roller conveyor system moves workpieces through the blasting process, ensuring all surfaces are treated uniformly.
Continuous Throughput
The Thai facility now feeds steel plates continuously through the machine. One operator loads plates at the infeed end; another collects them at the outfeed end. The machine runs continuously, processing plate after plate without stopping. Throughput tripled compared to the batch system.
Consistent, High-Quality Surface Finish
The six blast wheels (each delivering 250 kg/min of abrasive) cover the full width of the plate. Every surface receives the same blast intensity. The result is a uniform surface profile that meets coating specifications every time. Rework dropped to near zero.
Reduced Labor And Handling
The roller conveyor system eliminates manual loading and unloading of each piece. Plates move automatically through the industrial shot blasting machine. Labor requirements dropped from four operators to two. The facility now allocates workers to higher-value tasks.
Versatile Processing Capabilities
The machine handles a wide range of workpieces: steel plates up to 2000mm wide and 60mm thick, structural sections up to 2000×300mm, and workpieces from 1200mm to 12000mm in length. The Thai facility uses it for everything from bridge components to building frames.

Real Feedback From The Thai Steel Service Center
After six months of using the YG-6920 roller conveyor shot blasting machine, the operations director shared his results.
- Throughput: Tripled from 5 tons per shift to over 15 tons per shift.
- Labor: Reduced from 4 operators to 2.
- Surface quality: Consistent profile meeting all customer specifications. Rework dropped by 90%.
- Maintenance: The roller conveyor system requires only routine lubrication and abrasive top-up.
- Customer satisfaction: The facility secured two new contracts with major infrastructure contractors.
- Payback: The machine paid for itself in eight months through increased throughput and reduced labor.
The operations director said: “Thailand’s infrastructure boom means we need to process more steel faster. Our old batch system could not keep up. The YG-6920 roller conveyor shot blasting machine changed everything. We feed plates in one end and get perfectly blasted steel out the other. The continuous operation means no downtime between pieces. Our customers are happy with the consistent quality.”
An operator added: “The industrial shot blasting machine is straightforward. I load the plate onto the conveyor, set the speed, and the machine does the rest. The rollers carry the plate through smoothly. The dust collection system keeps the work area clean. I can process more plates in one shift than I used to process in three.”
