Tumbling Shot Blasting Machine QJ324–QJ3210 | Jinwo, Qingdao, China

Jinwo's Tumbling Shot Blasting Machine QJ324–QJ3210 cleans small and medium-sized workpieces in batches. High-speed impellers throw steel shot at the parts inside a sealed blasting chamber, removing sand, rust and scale and strengthening the surface.

Parts are carried on a wear-resistant rubber track (manganese steel tracks are also mentioned for the type), which tumbles them so every face is exposed to the blast. It suits parts that tolerate knocks and is offered in four sizes, with non-standard customisation available.

Frequently Asked Questions

• What size of workpiece can it handle? Maximum single piece weight is 6 kg on the QJ324, 10 kg on the QJ326, 15 kg on the QJ328 and 30 kg on the QJ3210.
• What output does it offer? Productivity runs from 0.3–0.8 t/h on the smallest model up to 1.5–2.5 t/h on the QJ3210.
• Is it suitable for delicate parts? It is intended for parts that are not sensitive to collision; the rubber track reduces knocks and scratches but parts still tumble.
• What should I send for a quotation? Send the workpiece type, material and weight, the batch size, the hourly output you need, the surface finish required, and any customisation you want.
