The Critical Separation Stage in Fertilizer Processing

Fertilizer (N-P-K) production — ammonia, urea, phosphate, potash, compound — centers on crystallization, evaporation, filtration. Centrifuges drive separation, dewatering, washing, and mother liquor recovery across urea granulation, ammonium chloride/sulfate recovery, phosphate purification, potash flotation.

Why Separation
Performance Matters？

In fertilizer production, the centrifuge does more than “separate the crystals” — it also affects product purity, nutrient recovery, crystal moisture, drying/granulation load, corrosion and maintenance, and waste treatment cost.

Nutrient Loss

Incomplete separation wastes nutrient liquor — a direct economic loss.

High Impurities

Adsorbed Ca, Mg, Fe — inadequate washing fails purity spec.

Crystal Breakage & Loss

Traditional equipment breaks crystals and loses fines — lowering recovery.

Corrosion & Maintenance

Corrosive, hard media wear out ordinary equipment — frequent downtime.

One Process. Two Separation Solutions.

For varying slurry concentrations and process conditions in fertilizer production, two continuous separation options: LWL and LWLZ.

LWL

Centrifugal Filtration

Screen Separation

Screw Differential Conveying

Standard solid-containing slurry, high throughput,
continuous washing required.

Which one
fits your
process?

LWLZ

Sedimentation Thickening

Screen Filtration

High feed fluctuation, low solids (5%–65%), dilute feed
needing pre-concentration.

LWL Horizontal Screen Scroll Centrifuge

Fully automatic at full speed — feed, filter-dewater, cake wash, and discharge all at
running speed, built for continuous fertilizer lines.

Continuous Automation

Full-speed continuous automation for fertilizer lines — high automation level.

Screw-push

Screw-push tumbling washes off adsorbed Ca, Mg, Na from crystals.

Low Cake Moisture

Low cake moisture — centrifugal filtration feeds drying and granulation directly.

Corrosion-resistant Design

Corrosion-resistant for aggressive media — wetted parts in 2205, Hastelloy, titanium.

Fully Enclosed, Explosion-proof

Enclosed, explosion-proof, leak-free-optional N₂ purge, O₂ monitoring.

LWL Series

LWLZ Horizontal Screen Decanter Centrifuge

LWLZ merges settling and filtration — thickening then screen filtration, all at full speed.
For fertilizer slurries with low solids and high swings.

Feed Tolerance Range

Wide feed tolerance — 5%–65% solids; dilute feed pre-thickened first.

Screen Filtration

Rear screen unit keeps online washing — displacing Ca, Mg from crystals.

Wetted Parts

Wetted parts in corrosion-resistant materials — for acidic fertilizer liquor.

Suitable Materials

Settling crystals: ammonium phosphate, potassium sulfate, potassium nitrate.
