Common Difficulties in Waste Oil Separation by Centrifuge

● High water content in waste oil, difficult to dehydrate thoroughly.

 Use three-phase centrifuge (oil-water-solid) for simultaneous separation.

● Large amount of solid impurities, easy to block the centrifuge.

 Optimize rotating speed and separation factor.

● Emulsified oil-water mixture, difficult to separate.

Preheat and add demulsifier to break emulsification.

● Low separation efficiency and long treatment time.

Adopt automatic slag discharge to prevent clogging.

● Centrifuge vibration caused by unbalanced feeding.

Use uniform feeding and dynamic balance system.

● Poor clarity of treated oil, high residual impurities.

Use uniform feeding and dynamic balance system.

Pre-filter coarse impurities to protect the centrifuge.
