Key Features:

Key Feature 1 — Continuous operation with high throughput

Continuous feeding, filtration, washing, dewatering and discharge are completed in one machine, making the LWL ideal for large-capacity production lines and stable 24/7 operation.

Key Feature 2 — Low residual moisture and high solids recovery

The combination of high centrifugal force and optimized solids conveying path allows effective liquid removal while maintaining high solids recovery and consistent cake quality.

Key Feature 3 — Efficient cake washing with low wash-liquid consumption

Built-in washing pipes and optional multi-stage washing arrangements provide effective displacement washing, helping reduce mother-liquor residue and improve final product purity.

Key Feature 4 — Stable conveying under fluctuating feed conditions

Hydraulic, planetary or cycloidal differential-drive options provide strong torque reserve and stable cake conveying, even when feed concentration or solids load changes.

Key Feature 5 — Durable structure for corrosive and abrasive service

Key wet parts can be manufactured from corrosion-resistant stainless steel, duplex grades, titanium or other special alloys. Wear-resistant protection is also available for abrasive applications.

Process Characteristics (Technical Analysis):

(1) Continuous separation with integrated filtration and conveying

The LWL Series performs continuous solid–liquid separation by combining a rotating filter screen with an internal scroll conveyor. This design eliminates the repeated batch cycles of conventional equipment and is well suited for uninterrupted industrial production.

(2) Thin cake filtration for effective washing and low moisture

Because the cake layer formed on the screen is relatively thin, washing liquid can penetrate more effectively, improving impurity removal and helping achieve lower final cake moisture.

(3) Flexible screen and cone-angle selection

Different screen structures and cone angles can be selected according to crystal size, washing duty and discharge behavior, improving adaptability to different products and operating conditions.

(4) Broad differential-drive options

Cycloidal, planetary and hydraulic differential systems are available to match different solids properties, feed concentrations and conveying torque requirements.

(5) Easy integration into automated process lines

The centrifuge can be supplied with local control, PLC/HMI or DCS integration, allowing connection to upstream crystallizers, reactors, dissolvers, wash systems and downstream dryers or conveyors.

Agrochemicals: Applicable to fertilizer intermediates, pesticide intermediates and other crystalline agrochemical products requiring continuous washing and dewatering.

Working Principle:

Slurry is continuously fed through the feed pipe into the inner cavity of the screw and then enters the rotating screen bowl near the small end of the drum. Under centrifugal force, the liquid phase passes through the filter screen and is discharged as filtrate, while solids are retained on the screen surface to form a cake. Due to the relative differential speed between the screw and the drum, the solids are conveyed continuously from the small end toward the large end of the drum. During this transport, further dewatering takes place. If washing is required, wash liquid is introduced through the built-in washing system to displace mother liquor and improve product purity. Finally, the dewatered solids are discharged continuously from the large end of the drum, completing continuous solid–liquid separation.
