The Critical Separation Stage in Boric Acid Processing
Boric acid crystal slurry from cooling crystallization requires solid-liquid separation — crystals feed drying, mother liquor recycles. Fine, viscous crystals and weakly acidic liquor demand minimal breakage and fine-crystal loss control.
Why Separation
Performance Matters？
In boric acid production, the centrifuge does more than “separate the crystals” — it also affects crystal moisture, mother liquor entrainment, fine-crystal loss, breakage rate, drying load, and liquor recovery efficiency.
Fine Crystals
Fine boric acid crystals are easily lost through misaligned screens — reducing yield.
Crystal Breakage
Traditional forced discharge causes crystal breakage — affecting particle size and quality.
Sticky Material
Viscous boric acid causes discharge bridging — disrupting continuous operation.
Mild Acid Corrosion
Weakly acidic boric acid liquor causes mild corrosion — affecting service life.
One Process. Two Separation Solutions.
For varying boric acid crystal slurry concentrations and process conditions, two continuous separation options: LWL and LWLZ.
LWL
Centrifugal Filtration
Screen Separation
Screw Differential Conveying
Coarse-particle, high-throughput boric acid crystal slurry.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
Fine-particle boric acid crystal slurry requiring low moisture.
LWL Horizontal Screen Scroll Centrifuge
Continuous solid-liquid separator for boric acid crystals and mother liquor — screw-push
discharge, for coarse particles, 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 centrifuge for your boric acid?
| Comparison Criteria | LWL | LWLZ |
|---|---|---|
| Discharge Method | Screw-push Discharge | Gravity Discharge (screw-assisted distribution) |
| Suitable Particle Size | Relatively Coarse 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 |
