The Critical Separation Stage in Food & Dairy Processing
Centrifuges separate salt crystals from mother liquor/impurity filtrate after reactive crystallization in inorganic salt production (sulfates, chlorides, nitrates, carbonates) and synthesis (metal salts, metathesis, neutralization), enabling rapid solid–liquid separation, dewatering, classification, clarification, impurity removal, and mother liquor recovery.
Why Separation
Performance Matters？
In inorganic salt production, centrifuges do more than separate crystals; separation performance also affects product purity, salt recovery, crystal moisture, downstream drying/calcination load, mother liquor recycling, and waste treatment costs.
High Moisture
Wet residue raises downstream disposal or resource-recovery cost.
Fine Slag Loss
Fine slag lost with salt liquor reduces solids recovery and contaminates the salt solution.
Chloride Corrosion
High chloride causes pitting corrosion — shortening equipment life.
AlN Hydrolysis
AlN hydrolyzes in water, releasing ammonia — oxygen monitoring or nitrogen purge needed.
One Process. Two Separation Solutions.
For varying slurry concentrations and fluctuating operating conditions in inorganic salt production, two continuous centrifugal separation solutions—LWL and LWLZ—are available.
LWL
Centrifugal Filtration
Screen Separation
Screw Differential Conveying
Conventional crystal slurry: high throughput, continuous
washing—inorganic salt crystallization.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
Inorganic salt slurries: widely fluctuating feed concentration,
low solids (5–65%), dilute feed requiring pre-concentration.
LWL Horizontal Screen Scroll Centrifuge
Fully automated high-speed continuous process—feed → dewatering → cake washing →
discharge—suited to continuous plant lines.
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.
LWL Series
LWLZ Horizontal Screen Decanter Centrifuge
LWLZ: integrated thickening + screen filtration; continuous full-speed feed, thickening, filtration, washing,dewatering, discharge; for low-solids, variable-concentration inorganic salt slurries.
Gravity Discharge
Gravity discharge — minimal crystal breakage.
Deliquoring
Longer residence and deliquoring time — lower discharge moisture.
Fine Particles
Suited to fine-particle ammonium sulfate slurry.
Bowl Cone Angle
Bowl cone angle optimized at 25° for gravity-slide discharge.
Screen Slotting
Optimized screen slots improve fine-crystal retention.
LWLZ Series
LWL or LWLZ?
How to Select the Right Centrifuge for Your Inorganic Salt Application?
| Comparison Criteria | LWL | LWLZ |
|---|---|---|
| Discharge Method | Screw-push Discharge | Gravity Discharge (screw-assisted distribution) |
| Suitable Particle Size | Medium Particles | Fine Particles |
| Throughput | High Throughput | Slightly Lower Than LWL At The Same Spec |
| Discharge Moisture | Relatively Low | Lower |
| Particle Breakage | Minimal | Even Less |
| Typical Applications | High-capacity Continuous Production | Fine particles, Low Moisture Requirement |
