Cleaning / Heat Scale and Rust Removal
Continuous Operation
SURFEX® designs and manufactures the Roller Conveyor Type Shot Blasting Machine (Continuous Type) for a wide range of components (Bright Bars / Round Bars / Hex Bars / Square Bars / Flats / Billets / Rebars / Pipes / Tubes / Rods / Structural Jobs / Plates / etc.).
The jobs are loaded on the inward side of the roller conveyor arrangement. The jobs are passed through an inward tunnel of the shot blasting machine and enter the blasting chamber for blasting purpose. Suitable number “Surfex” advanced blast wheel stations (At the top & At the bottom of the job) are located strategically on the cabinet, which fires blasting abrasive media on the jobs. The jobs are shot blast homogeneously all around. The blasted jobs moves forward, & enter the outlet tunnel, and further moves to the conveyor at the outlet side for job unloading.
SURFEX® equipment includes a fully automatic Dust Collection System to remove dust and fines from the blast cabinet.
SURFEX® engineers the Roller Conveyor Type Shot Blasting Machine for continuous, high-speed surface preparation of steel plates, structural steel, H-beams, I-beams, pipes and fabricated components. Top and bottom mounted blast wheel stations deliver homogeneous, all-around cleaning as jobs move through the inward tunnel, blast chamber and outward tunnel without interruption.
A Roller Conveyor Type Shot Blasting Machine is a through-feed surface preparation system where components move on a powered roller bed directly through the blast chamber. Suitable numbers of Surfex advanced blast wheel stations, positioned both at the top and at the bottom of the job, fire abrasive media as each component passes beneath and beside them, producing homogeneous, all-around blast coverage without manual repositioning.
Jobs are loaded on the inward side of the conveyor, pass through an inward tunnel into the blasting chamber, and continue forward through an outward tunnel to the unloading conveyor once cleaning is complete. Because the line never stops for individual components, a Continuous Roller Conveyor Shot Blasting Machine keeps throughput high and cycle time predictable even on long production runs.
As a fully Automatic Roller Conveyor Shot Blasting Machine, the system is built for steel plates, billets, rebars, structural jobs, bright bars, round bars, hex bars, square bars, flats, pipes, tubes and rods — giving fabrication shops a single line capable of handling a wide mix of profiles rather than dedicated equipment for each shape.
SURFEX® equips every machine with a fully automatic dust collection system to remove dust and fines from the blast cabinet, keeping visibility and media quality consistent across every shift.
Fabrication shops sometimes refer to this equipment simply as a Roller Conveyor Blast Machine or Roller Conveyor Shot Blast Machine, though the underlying engineering is identical: a powered roller bed carrying components through a sealed blast chamber fitted with top and bottom blast wheel stations. Whichever term your team uses internally, the specification questions are the same — conveyor width, blast wheel count, tunnel length and required cycle time.
SURFEX® has supplied roller conveyor and other through-feed shot blasting equipment since 1977, and that history shapes how each new machine is engineered: tunnel sealing, wheel placement and reclaim sizing are refined from decades of feedback gathered directly from fabrication shop floors rather than developed in isolation.
Every job follows the same continuous path from loading to unloading on the Through Feed Shot Blasting Machine.
Components are placed on the inward roller conveyor at the loading side of the machine.
Jobs pass through a sealed inward tunnel that keeps abrasive contained within the blast chamber.
Top and bottom blast wheel stations fire abrasive media, blasting the job homogeneously all around.
The cleaned component exits through the outward tunnel, sealing the chamber from the unloading side.
Spent media is reclaimed, screened and returned to the storage hopper for continuous reuse.
Finished components move onto the outlet conveyor for unloading while the line keeps running.

A Steel Plate Roller Conveyor Shot Blasting Machine setup and a Structural Steel Roller Conveyor Shot Blasting Machine setup often share the same conveyor frame, with blast wheel angle and abrasive intensity adjusted for plate thickness versus beam flange geometry.
A dedicated Steel Plate Shot Blasting Machine mode cleans mill scale and rust from flat plate stock before fabrication or coating.
An H Beam Shot Blasting Machine configuration, also called an H Beam Roller Conveyor Shot Blasting Machine, reaches both flanges and the web for full-profile coverage.
An I Beam Shot Blasting Machine setup targets flange faces and the web centreline in a single continuous pass.
A Pipe Shot Blasting Machine pass cleans the outer diameter of round steel pipe and tube stock before coating.
Welded fabrication assemblies and angles are cleaned on the Structural Steel Shot Blasting Machine line before painting.

Every Industrial Roller Conveyor Shot Blasting Machine from SURFEX® is built with robust, long-life components as standard.
A reinforced roller bed keeps heavy plates, beams and pipes moving smoothly through the blast chamber.
Surfex advanced blast wheel stations maximise abrasive throw energy for faster, more consistent cleaning.
Screw conveyors and bucket elevators return usable media to the storage hopper for continuous reuse.
PLC-based control coordinates conveyor speed, blast wheel operation and dust collection automatically.
Multi-layer rubber sealing at the inward and outward tunnels keeps abrasive contained within the chamber.
Wear-resistant manganese steel lining protects the chamber from continuous abrasive impact.
An Automatic Shot Blasting Line built around a roller conveyor gives fabrication shops a genuinely Automated Shot Blasting System rather than a semi-manual cabinet requiring an operator at every cycle. Precise abrasive control valves regulate media flow to each blast wheel independently, so coverage can be balanced across plate thickness or beam profile without over-blasting lighter sections.
Surface preparation grades referenced in international standards such as SSPC and ISO 8501 are commonly targeted using this equipment, giving structural steel exporters a consistent, documented starting point regardless of which country the finished steelwork is shipped to.
An intelligent dust extraction system works continuously alongside the blast wheels, meeting the visibility and housekeeping standards expected on a modern Continuous Shot Blasting Machine line. Combined with wear-resistant manganese steel lining and multi-layer rubber sealing at both tunnels, the result is a machine designed for years of high-utilisation service in structural steel and fabrication environments.
Blast wheel wear parts — blades, control cages and liner plates — are the components most exposed to continuous abrasive impact, and their accessibility for inspection and replacement is a major factor in total cost of ownership. SURFEX® designs wheel housings with quick-access panels, so routine wear-part changes can be scheduled during normal maintenance windows rather than causing unplanned production stoppages.

A Shot Blasting Machine for Structural Steel built on the roller conveyor platform is widely used in steel fabrication units, pre-engineered building (PEB) manufacturing, shipyards, railway and metro component production, and forging and casting industries. Each of these sectors relies on consistent surface preparation before painting, galvanising or coating, and inconsistent cleaning is one of the most common causes of premature coating failure.
For fabrication shops, a Shot Blasting Machine for Steel Fabrication replaces multiple manual blasting stations with a single continuous line, reducing both labour cost and the surface-quality variation that comes from operator-dependent manual blasting. A Shot Blasting Machine for Steel Plates configured for plate stock and a Steel Profile Shot Blasting Machine configured for beams and angles can often share the same conveyor platform with adjusted blast wheel settings.
A Steel Fabrication Shot Blasting Machine line is typically positioned immediately before painting or galvanising in the production sequence, since blast-cleaned steel oxidises again within hours if left exposed. Sequencing the roller conveyor line directly ahead of the coating booth keeps the time between cleaning and coating short, which is one of the simplest ways fabrication shops improve coating adhesion without changing the coating specification itself. A Steel Structure Shot Blasting Machine used this way becomes as much a scheduling decision as an equipment decision.
Uniform cleaning with high repeatability is the primary benefit fabrication shops cite when moving to an Automatic Roller Conveyor Shot Blasting Machine: because blast wheel position, conveyor speed and abrasive flow are fixed process parameters rather than operator judgement calls, the surface profile achieved on the first plate of a shift matches the surface profile on the last. Continuous material flow keeps output predictable, which matters when the blasting line feeds directly into a painting or galvanising schedule downstream.
Reduced labour cost follows naturally from automation: a single operator can manage loading and unloading at both ends of the line rather than running an entire manual blast cycle personally. Combined with a longer service life from durable, wear-resistant components, the total cost of running a Roller Conveyor Blast Machine over several years compares favourably with the ongoing labour and rework cost of manual blasting for medium-to-high volume structural steel work.
Why structural steel and fabrication shops move from manual booths to an Automated Shot Blasting System as volume grows.
| Criteria | Roller Conveyor Shot Blasting Machine | Manual Blast Booth |
|---|---|---|
| Throughput | Continuous, through-feed processing | One batch at a time, operator-paced |
| Coverage Consistency | Fixed blast wheel geometry, repeatable | Depends on operator technique |
| Labour Requirement | Load/unload only, largely automated | Continuous manual operation required |
| Best Suited For | High-volume plates, beams, pipes, profiles | Small batches, irregular shapes, touch-ups |
