Sample the actual feed

A screen trial is useful only when the sample represents the material the machine will receive. A clean, dry sample taken from storage may behave differently from feed arriving directly from a dryer or conveyor. Record where and when the sample was collected, and note any changes between batches.

Record the variables

Include the particle size distribution, moisture condition, bulk density if known, and the required separation size. Keep lumps and fines in their normal proportions instead of removing them before testing. Label separate samples when the process handles more than one material condition.

Use the results carefully

Compare feed, accepted material and oversize samples using the same sampling method. A trial can inform configuration discussions, but it does not establish performance for every future batch. Share the material record and required throughput with Tianteng Machinery so the screening arrangement can be reviewed against the actual application.
