How to separate waste oil from oily sludge

LWS520 Waste Oil Centrifuge

The LWS horizontal screw centrifuge is a new type of Three-phase horizontal screw centrifuge mainly suitable for three-phase separation (oil-water-solid). It is widely utilized in waste motor oil separation, oil sludge treatment, and crude oil separation.

What is a Decanter Centrifuge

A horizontal spiral centrifuge utilizes a rotating screw conveyor mechanism to separate solid particles or liquid-liquid mixtures based on density. By subjecting the mixture to high centrifugal force, denser components move towards the outer edge while lighter components stay at the center.

⚙️

Structure: Consists of a column cone, spiral discharge device, differential system, and advanced electrical controls.

⚡

Efficiency: Capable of 24-hour continuous operation and separating materials ranging from 0.002 to 5um.

Working Principles

2-Phase Centrifuge Principle

Solid-phase particles settle on the drum wall under centrifugal force, while light liquid settles at the innermost part. The screw feeder discharges solids continuously while liquid is released via the outlet.

3-Phase Centrifuge Principle

Realizes Solid-liquid-liquid separation. Two liquid phases and one solid phase are stratified based on centrifugal force. The process is fully automatic, closed, and continuous.

Frequently Asked Questions (FAQ)

What materials are used for the centrifuge construction?

Depending on the requirement, contact parts are made of austenite stainless steel (304, 316L, 904L, Duplex 2205), or other anti-erosion alloys.

What is the expected lifespan of the LWS520 model?

The centrifuge is designed for heavy-duty industrial use with a service life of approximately 20 years.

Can this machine handle 24-hour continuous operation?

Yes, the LWS520 is specifically engineered for 24-hour continuous automatic feeding and discharge.

What is the difference between 2-phase and 3-phase separation?

2-phase separation splits solids from a single liquid, while 3-phase separation simultaneously separates solids and two different liquid phases (e.g., oil and water).

What safety features are included?

The system includes safety overload protection, explosion-proof options, and PLC-controlled automatic adjustment of differential speeds.

What is the typical oil recovery rate from sludge?

Approximately 80% to 90% of the oil content can be successfully recovered using this decanter centrifuge technology.
