Automatic Mesh Belt Shot Blasting Machine for Scaffolding and Paver Parts

Why a continuous mesh belt line for high-volume small parts

Cuplock scaffolding couplers and paver components are produced in very large batches. Batch-type machines such as tumble or rotary tables still impose a load-and-unload dwell on every cycle, which caps real throughput. A mesh belt line keeps parts moving in and out without a per-batch stop, so hourly volume tracks belt speed and loading density rather than batch count.

What the line is built around

• Continuous in and out — parts enter and leave on the belt with no cycle dwell, so throughput is set by belt speed, not batch size.
• Open mesh deck — abrasive and loosened scale fall through the belt instead of re-contacting the workpiece, keeping the surface clean between passes.
• No fixtures required — parts rest directly on the belt, which suits repetitive small hardware that would be slow to fixture one by one.
• Adjustable speed and side wheels — belt speed and turbine position are tuned to part size so the top and sides receive an even blast.

Effect and where it stops working

The line brings small, repetitive steel parts to a SA 2.5 finish at high and steady volume, with the abrasive loop closed back to the separator. It is not the right tool below a certain part size or above a certain weight: parts that are too small fall through the mesh, and long or heavy pieces belong on a roller table. Exact belt pitch, speed and turbine count are set after we review your workpiece geometry, finish target and daily volume.

What we need from you

Send the part drawing or a sample, your required cleanliness standard, and your daily throughput target. We confirm mesh pitch, belt speed and turbine layout against your actual parts before building the line.
