COMPARE THE CORE MACHINES.
Six machine types cover most workpiece handling in a foundry or fabrication plant. The table uses the recorded figures for each type; a dash means the value is not published for that machine and is confirmed per project.

| Handling concept | Batch cell, overhead hook | Continuous line, powered rollers | Continuous line, open mesh belt | Batch drum, rotating belt | Walk-behind, floor head | Self-propelled, road head |
| Typical workpieces | Castings, forgings, welded assemblies | Plate, beams, bars, weldments | Small and medium parts in mixed batches | Fasteners, stampings, small castings | Concrete floors with coatings | Asphalt and concrete road surfaces |

| Where it stops | Blind pockets need manual touch-up | Very short parts tip between rollers | Parts smaller than the mesh can fall through | Parts that nest or have thin walls can be marked | About 50 mm at edges is finished by hand | About 50 mm at edges; potholes are patched first |
Throughput is stated for ferrous workpieces in tonnes per hour; coverage is stated for surface preparation in square metres per hour, because the two are different dimensions and cannot be compared directly. Machine weight is the recorded machine mass, not the shipping weight.
How to choose between them
Choose by how the workpiece is handled, not by the largest number in the table. Parts that can touch each other go to a tumble belt. Heavy or fragile parts that must stay separated hang from a hook. Long plate, beams and profiles run over rollers. Small mixed batches travel on a mesh belt. Concrete floors and asphalt roads are prepared by the walk-behind floor machine and the self-propelled road machine, which do not process metal parts.

Which shot blasting machine should I choose?
Start from the workpiece. Parts that can tumble without damage run in a tumble belt; heavy or fragile parts that must stay separated hang from a hook; long plate, beams and profiles pass over a roller conveyor; small mixed parts travel on a mesh belt. Floor and road machines prepare concrete and asphalt, not metal parts.
What is the difference between a hanger type and a roller conveyor machine?
A hanger machine is a batch cell: the part hangs from a hook inside the chamber and is blasted while rotating. A roller conveyor is a pass-through line: long steel parts travel over rollers through fixed blast stations. The hanger suits complex castings, while the roller line favours plate and profiles at higher throughput.
Which machine has the highest throughput?
For ferrous parts the roller conveyor line records the highest range at 2.0–5.0 t/h, against 1.0–3.0 t/h for a mesh belt, 1.0–2.0 t/h for a hanger and 0.6–1.2 t/h for a tumble belt. For surface preparation the road machine covers 80–150 m²/h and the floor machine 40–80 m²/h per pass.
Are prices published for these machines?
No. Every machine is configured around the workpiece, material, dimensions and required output, so pricing is quotation-only. Send a drawing, material, maximum dimensions and expected output to receive a configuration review and a quotation.
