Factory Acceptance Checks for a Mechanically Agitated Flotation Cell
Practical pass or fail checks for a 4 m³ mechanically agitated flotation cell, from impeller and drive verification to no-load run tests and documentation review.
For a 4 m³ mechanically agitated flotation cell, decide before the factory acceptance test whether the unit will be accepted on no-load running alone or also on witnessed mechanical checks. A no-load run confirms the 15 kW agitation motor and drive train turn freely, but it does not prove the 650 mm impeller is correctly positioned or that the cell holds volume as intended.
Build the acceptance test around measurable checks. Confirm the effective cell volume of 4 m³ by dimensioned drawings or a water-fill check if the supplier permits it. Verify the impeller diameter of 650 mm and its shaft alignment against approved drawings. Record motor current and vibration during a defined no-load period, and compare against limits agreed in the purchase order. Ask whether the stated capacity range of 2–4 m³/min is a design reference only and what test, if any, the supplier proposes to support it.
Before requesting a quote, confirm with the supplier which checks are witnessed, what acceptance limits apply to motor current and vibration, whether a water-fill volume check is possible, and which drawings and test records will be issued with the cell.
