Thermocouple failed or drifted causing incorrect temperature feedback
Rotor coolant flow insufficient from a blocked water circuit or pump fault
Temperature controller setpoint incorrect for the compound being mixed
Scale buildup in the rotor cooling channels reducing heat transfer
Rotor end seals worn past their service limit from abrasive compound
Seal lubrication (seal oil or grease) depleted or contaminated
Rotor shaft surface worn at the seal running face
Mixing chamber operating pressure elevated from ram force settings

How to fix drop door hydraulic faults on a Farrel-Pomini BR / F-Series Banbury mixer
Drop door hydraulic faults prevent batch discharge and can cause compound to degrade in the chamber. Check hydraulic pressure, door seal, and door latch solenoid before forcing the door open.
How to fix rotor seal leakage on a Farrel-Pomini BR / F-Series Banbury mixer
Rotor end seal leakage contaminates the batch and allows compound to escape the mixing chamber. Replace the rotor seals before leakage reaches the drive side bearing, which is much more expensive to repair.
How to fix temperature control faults on a Farrel-Pomini BR / F-Series Banbury mixer
Temperature control faults cause under- or over-mixed compound and scorch risk. Verify the temperature controller setpoint, rotor coolant flow, and thermocouple continuity before adjusting mixing time.
