Testing a Circular Vibrating Screen With Your Own Rock or Ore
A buyer's guide to planning a circular vibrating screen demonstration using the buyer's actual rock or ore, with practical questions for the RFQ, trial, and acceptance test.
Ask the supplier to run the demonstration on your rock or ore, not on a generic sample. Screening performance depends heavily on feed gradation, moisture, and particle shape, so a trial with your material is the most useful evidence you can gather before committing to a circular vibrating screen purchase.
For the RFQ, state your feed size distribution, expected moisture range, and target product splits. The catalog reference values list a 12.6 m² screening area, maximum feed size of 200 mm, capacity range of 230–800 t/h, and 22 kW motor power; treat these as reference values only and ask the supplier to confirm what a proposed unit would achieve with your material. During the demonstration, compare throughput, oversize carryover, and blinding or pegging tendencies against your target. Ask how the trial unit's deck configuration, amplitude, and media compare with the unit you would receive.
For acceptance, agree in advance on sampling methods, test duration, and the material batch to be used, and record moisture and feed gradation alongside results.
Before requesting a quote, confirm with the supplier which material sample will be used, how results will be measured, and whether the tested configuration matches the offered machine.
