Home / Airless Shot Blasting Machines / Roller Conveyor Shot Blasting Machine Manufacturer
The roller conveyor system moves beams, plates, and structures smoothly through the blasting chamber. Continuous operation ensures rapid throughput, uniform cleaning, and reliable production performance.
The roller conveyor shot blasting machine is a continuous, high-output system for cleaning long, flat steel products, such as plates, beams, channels, angles, and fabricated sections. Parts ride through the blasting chamber on powered rollers, so a steady stream of material is cleaned to the same standard in one go.
Inside the chamber, multiple high-speed blast-wheel units throw abrasive at set angles onto the top and bottom of each part. This airless roller conveyor-type shot blasting machine removes rust, mill scale, and old coatings, leaving a clean profile ready for painting or coating.
Available Configurations
For sheet, plate, and other flat components that have a length
Smart Process Overview
Parts are placed on the inlet rollers and carried steadily into the blast chamber. The rollers turn at a set speed, so the material moves through the abrasive stream without stopping, and long sections feed through end to end.
Inside, several shot blasting turbine units are fixed above and below the roller line. They throw abrasive at high speed onto both faces of the part, so the complete surface is cleaned as it passes.
Used abrasive drops into the hopper and is carried by a screw conveyor and bucket elevator to the separator, which cleans them for reuse. Dust is drawn off by the dust collector, and the cleaned parts leave on the outlet rollers, ready for coating.
Built With Precision Components
Blast Wheel Units
10-HP to 30-HP turbines are set above and below the roller line for full top-and-bottom coverage.
Roller Conveyor Bed
Powered rollers with VFD speed control that carry plates and sections steadily through the chamber.
Blasting Chamber
Manganese steel-lined tunnel with replaceable wear plates to take constant abrasive impact.
Abrasive Circulation System
Screw conveyors, bucket elevator, and air wash separator that recover and clean abrasives for reuse.
Dust Collection System
Bag filter or cartridge collector with pulse jet cleaning for a clean chamber and work area.
Entry and Exit Seals
Rubber curtain vestibules at both ends keep abrasives inside the chamber.
Electrical Control Panel
PLC-based panel with interlocks and safety features for steady, controlled running.
Custom Engineered Mechanism
The roller conveyor type uses powered rollers to move parts smoothly through the chamber, which makes it the natural choice for plates, beams, H and I sections, and structural fabrication. The flat roller bed supports long and heavy material steadily, so nothing jams during the pass.
It is the most widely used configuration because it handles high volume, gives a consistent finish, and fits easily into a production line ahead of a coating or primer stage.
The heavy-duty roller conveyor shot blasting machine is built for fabrication and structural work that runs long, flat steel in volume. The multiwheel arrangement and consistent roller feed produce a reliable result with minimal intervention required between stages.
It fits neatly in line before painting or galvanizing, which makes it a practical automatic shot blasting machine for plants that want cleaning and coating to run as one flow.

Additional System Enhancements
Gives central control and live monitoring so blasting runs steadily with less manual input.
Sets conveyor speed to the part thickness for the right dwell time and an even clean.
Feeds and offloads plates and sections to cut, handling and keeping the line moving.
Draws contaminants out of the media so cleaning quality stays steady and abrasive lasts longer.
Watches media quantity so long production runs blast without interruption.
Tops up abrasive automatically to hold output and cut downtime between batches.
Keeps the chamber clean and blocks sparks from reaching the dust system for safer running.
Clears leftover abrasive and dust from parts as they exit for a clean surface.
Regulate abrasive flow automatically for even blasting and controlled media use.
Lowers operating noise around the production line for a safer working area.
Links blasting to the coating stage, so material flows straight from clean to primer.
It is a through-feed machine that carries plates, beams, and sections on powered rollers through a blast chamber. Wheels above and below clean both faces in one go.
Plates, sheets, beams, channels, angles, and long fabricated sections. The flat roller bed is made to carry long, heavy steel steadily through the chamber.
It cleans in a continuous flow rather than batch by batch, so output is high, the finish is even, and long sections need far less handling.
Blast wheels are fixed above and below the roller line, so the top and bottom faces are blasted together as the plate passes through.
Steel fabrication, PEB, steel plants, oil and gas, railways, and heavy engineering use it to prepare plates and structural steel before coating.
Yes. The rollers run at a variable speed, so heavier or thicker steel can move more slowly for a deeper clean, and lighter sections faster.
Yes, it can be synchronised with primer, paint, and coating lines so that cleaned steel goes straight into the coating stage.
Yes, options such as SCADA controls, heavy-duty rollers, thickness detection, pre-heating zones, and automatic loading can be provided.
