Start with the inlet condition

A square tumbler screen trial should record how material reaches the working deck. If the feed concentrates in one area, part of the available surface may receive a different load from the rest. This guide focuses on feed distribution, rather than assuming that a change of machine size is the first answer.

Record the upstream arrangement

Describe the feeder type, discharge position and normal variations in feed delivery. Include the transition between the feeder and screen inlet. Note whether material arrives steadily or in batches. Keep the trial arrangement representative of the planned production line.

Observe only through approved means

Use the manufacturer approved observation method and maintain guards and covers in their required positions. Do not open the equipment or insert a tool while it is running. Where direct observation is unavailable, discuss a suitable inspection or test method with the supplier.

Compare distribution with the separated product

Take samples from the outlets using the agreed procedure. Record the feed condition alongside the fraction results and any signs of local accumulation found after safe shutdown. If the distribution is uneven, review the inlet transition and feeder arrangement before making unrelated setting changes.

Document the agreed arrangement

Keep a drawing or photographs of the tested feed path with the trial record. Send Tianteng the material details, feed method and inlet layout when discussing a square tumbler screen. Acceptance should reflect the tested arrangement and required size fractions; a result obtained with one feeding method does not establish performance under every other condition.
