Factory Acceptance Checks for a Circular Vibrating Screen

Before signing off a factory acceptance test for a circular vibrating screen, decide how you will judge motion, structure, and documentation, not just whether the unit runs. Ask the supplier to propose measurable checks tied to your duty: for example, how screen amplitude and orbit are verified at operating speed, and what tolerance counts as a pass.

Use the catalog reference values as discussion points, not guarantees for the supplied model: 12.6 m² screening area, 200 mm maximum feed size, 230–800 t/h capacity range, and 22 kW motor power. In the RFQ, ask which of these are design targets and which will be demonstrated at the FAT. For rock and ore screening, request the test feed description and how capacity checks will be run, since a no-load run cannot confirm throughput.

Practical pass or fail items can include: documented inspection of welds and fasteners, verified guard and drive alignment, recorded running current against the motor rating, and a vibration reading at agreed points. Ask whether the test stand can load the screen, and if not, state clearly that capacity is accepted by design review rather than test.

Before requesting a quote, confirm with the supplier what the FAT will actually measure, which instruments and calibration records are used, who witnesses and signs, what pass limits apply, and which deviations must be corrected before shipment.
