1.Under high-speed rotation, waste oil is thrown onto the filter wall.
● Liquid oil passes through the filter medium and is discharged.
● Solid impurities, sludge, and residues are intercepted on the filter surface.
After separation, the solid cake is removed by scraper, realizing high-efficiency solid-oil separation.
2. Advantages
● High dewatering & deoiling efficiency, low residual oil in sludge
● Fast treatment speed, suitable for industrial waste oil treatment
● Fully closed structure, safe and environmentally friendly
● Easy to clean and maintain, suitable for oily materials
● Good separation effect for fine impurities in waste oil
3. Pain Points / Difficulties
● Filter cloth clogging : Oily sludge and fine particles easily block filter pores, reducing filtration rate.
● High viscosity influence : High-viscosity waste oil flows slowly, leading to incomplete separation.
● Oil and sludge adhesion : Oily cake sticks strongly to filter cloth, difficult to discharge fully.
● Residual oil in cake : Part of oil is trapped in sludge, causing oil loss.
4. Solutions
● For high viscosity
• Preheat waste oil properly to reduce viscosity
• Optimize rotating speed and feeding rate to improve flow
● For adhesion and difficult discharge
• Use peeler scraper + air blowing to ensure full discharge
• Select smooth, non-stick filter media
● For high residual oil
• Extend centrifugal dewatering time properly
• Use two-stage separation (sedimentation + filtration centrifuge)
