The Critical Separation Stage in Ammonium Sulfate Processing
Ammonium sulfate (chemical/coking byproduct) crystallizes from evaporated liquor. Separation splits crystals from mother liquor, cuts entrainment for drying feed, and recycles liquor upstream — the centrifuge drives yield, moisture, and drying energy.
Why Separation
Performance Matters？
In ammonium sulfate production, the centrifuge does more than “separate the crystals” — it also affects crystal moisture, mother liquor entrainment, fine-crystal loss, drying load, and liquor reuse efficiency.
High Moisture
Wet crystals increase downstream drying load and energy use.
Fine Particle Loss
Fine powder lost with the liquid phase lowers product recovery.
Mother Liquor Entrainment
ntrained mother liquor hurts downstream drying and lowers liquor reuse efficiency.
Continuous Production
Scaled production needs continuous feed, separation, and discharge — equipment stability directly sets capacity.
One Process. Two Separation Solutions.
For varying slurry concentrations and process fluctuations after ammonium sulfate crystallization, two continuous separation options are offered: LWL and LWLZ.
LWL
Continuous Screen Filtration
Screw Conveying
Deliquoring
Medium-particle, high-throughput ammonium sulfate
crystal slurry conditions.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
Fine-particle ammonium sulfate slurry requiring lower moisture.
LWL Horizontal Screen Scroll Centrifuge
Continuous solid-liquid separation for ammonium sulfate crystals and liquor —screw discharge; medium-particle, high-throughput.
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
Gravity discharge — solids slide down the conical bowl under centrifugal force: longer residence,
better deliquoring; ideal for fine ammonium sulfate slurry.
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 choose the right ammonium sulfate centrifuge for you?
| Comparison Criteria | LWL | LWLZ |
|---|---|---|
| Discharge Method | Screw-push Discharge | Gravity Discharge (screw-assisted distribution) |
| Applicable Particle Size | Medium Particles | Fine Particles |
| Throughput | High Throughput | Slightly Lower Than LWL At The Same Spec |
| Discharge Moisture Content | Relatively Low | Lower |
| Crystal Breakage | Minimal | Even Less |
| Typical Applications | High-capacity Continuous Production | Fine-crystal, Low-moisture-spec Production Lines |
