Factory Acceptance Checks for a Tumble-Belt Shot Blasting Machine
Buyers should agree pass or fail checks for batch load, part weight, volume, and rated productivity before signing off a tumble-belt shot blasting machine at the factory acceptance test.
Before the factory acceptance test, decide how the machine will be judged against your own parts, not just a demonstration batch. A practical approach is to define a representative load and a measurable result for each check, then agree in the request for quotation how each will be witnessed and recorded.
Ask the supplier to run a batch at the stated 200 kg load and to include parts up to the 10 kg maximum individual part weight, since tumbling behaviour and part damage risk can differ with size and shape. Confirm how the 0.15 m³ effective volume will be demonstrated, for example by loading a defined mix of your parts. For rated productivity of 0.6–1.2 t/h, agree the part mix, load size, and timing method, and treat these catalog values as reference figures rather than guarantees for your parts. Useful pass or fail questions include: does the batch tumble without jamming, are parts discharged completely, and is surface condition assessed against an agreed sample?
Before requesting a quote, confirm with the supplier which checks they will accept, what test parts and records they need, and how deviations from the reference values will be handled.
