The Critical Separation Stage in Sodium Chloride Processing

NaCl crystals from evaporative or cooling crystallization need solid-liquid separation to recover crystals and cut mother liquor entrainment for downstream drying/refining. The centrifuge continuously separates crystals from mother liquor — directly affecting yield, moisture, and drying energy.

Why Separation
Performance Matters？

The centrifuge isn’t just there to “pull the salt out” — how well it separates also drives crystal moisture, mother-liquor carryover, recovery, the drying load downstream, and even how fast the unit corrodes and needs servicing.

High Moisture

Wet crystals increase the downstream drying load and energy consumption.

Crystal Loss

Fine crystals are lost with the mother liquor, reducing the product recovery rate.

Corrosion Risk

The sodium chloride mother liquor is corrosive to ordinary stainless steel, affecting equipment service life and product purity.

Maintenance Cost

Screen clogging, bearing seal failure, and insufficient wear resistance increase maintenance costs.

One Process. Two Separation Solutions.

To address varying crystal slurry concentrations and operating-condition fluctuations after sodium chloride crystallization, we offer two types of continuous centrifugal separation solutions: the LWL and the LWLZ.

LWL

Continuous Screen Filtration

Screw Conveying

Deliquoring

Conventional solid-bearing crystal slurry — requires continuous
separation, with the screen retaining the crystals.

Which one
fits your
process?

LWLZ

Sedimentation Thickening

Screen Filtration

Low solids content, fine particles, large concentration fluctuations —
requires pre-concentration before filtration.

LWL Horizontal Screen Scroll Centrifuge

Continuous solid-liquid separation equipment for sodium chloride crystals and mother liquor.

Corrosion-resistant Materials

Main parts—bowl, screw, etc. can be made of corrosion-resistant stainless steel or titanium alloy.

Filtration Screen

Dedicated filtration screen, 0.5mm thick—longer service life.

Adjustable Differential

Bowl speed is steplessly adjustable; screw differential speed adjustable in steps or steplessly.

Circulating Lubrication

Simple, reliable circulating lubrication — with pressure regulation, oil filtration, and water cooling.

Safety Protection

Speed, over-vibration, motor overload / overheat, and zero-differential protection.

LWLZ Horizontal Screen Decanter Centrifuge

Cont-filter centrifuge: feed, wash/dew. 0.1–10mm (opt 0.3–5); fib/sed. Low/fine NaCl → LWLZ conc-filter.

Handles Varying Slurry Concentrations

Low-solids feed is pre-thickened before the filtration stage.

Suited to Fine-particle Materials

Solid-liquid separation in two stages: sedimentation and filtration.

Combines Thickening And Filtration

Front stage handles liquid-solid separation; rear stage further filters and deliquors.

Continuous Production

Suited to continuous production.

Washing Can Be Added

A washing device can be added during filtration according to product purity requirements.
