Description
LLWZ‑450 Dual‑Cone Screen Scroll Discharge Centrifuge for Chemical Crystal Solid‑Liquid Separation
Product Introduction

The LLWZ Series Pre-Thickening Screen Scroll Discharge Centrifuge creatively combines the advantages of a horizontal screw decanter centrifuge and a screen scroll discharge centrifuge. It is a continuous, dual-cone structured, concentrating filtration centrifuge featuring large processing capacity, low energy consumption, stable performance and excellent separation efficiency.

This equipment can continuously feed, pre-thicken, wash, dewater and discharge the suspension while running at full speed, which greatly facilitates automated operation. It is recognized as separation equipment with superior structure, advanced technology, high efficiency and low consumption in the field of solid-liquid separation machinery.

This model is specially recommended for chemical and pharmaceutical crystalline separation where the mother liquor has low solid content or contains oily, colloidal or organic matter. It has been successfully applied to sodium chloride, sodium carbonate, ammonium sulfate, copper sulfate, oxalic acid, citric acid, lactose, PVC and plastic particles.

Working Principle

The machine adopts a unique dual-cone structure integrating a settling section and a filtering section. The suspension first enters the settling drum, where the pre-thickening process takes place under centrifugal force; the concentrated slurry then moves to the screen scroll discharge section, where mother liquor is filtered out through the screen while the solid cake is continuously conveyed and discharged by the scroll.

Because feeding, concentration, washing, dewatering and discharge are all completed at full speed in one continuous process, the machine achieves high throughput with low energy consumption and stable separation results.

Key Features
  • Integrated pre-thickening and screen filtration in one dual-cone continuous machine
  • Full-speed continuous feeding, concentration, washing, dewatering and discharging
  • Large processing capacity with low energy consumption
  • Stable performance and excellent separation efficiency
  • Suitable for automated operation, reducing labor cost
  • Widely used in chemical, environmental protection, salt production, mining and pharmaceutical industries
  • Particularly effective for crystalline particles in mother liquor with low solid content or containing oily, colloidal or organic matter

Due to its separation principle and structural characteristics, the machine is material-specific. Material analysis and pilot tests should be carried out before model selection to confirm applicability and separation performance.
Frequently Asked Questions
Q1: What materials can the LLWZ centrifuge handle?
It is widely applied to solid-liquid separation of crystalline particles, especially from mother liquor with low solid content or containing oily, colloidal or organic matter. Successful applications include sodium chloride, sodium carbonate, sodium sulfate, ammonium sulfate, copper sulfate, mirabilite, oxalic acid, citric acid, soda ash, sodium bicarbonate, p-nitroaniline, trichloroisocyanuric acid (TCCA), lactose, PVC and plastic particles.
Q2: Can the machine run continuously?
Yes. Feeding, pre-thickening, washing, dewatering and discharging are completed continuously at full speed, which makes automated production easy to realize.
Q3: How to choose the right model?
Because the machine is material-specific, we recommend sending your material for analysis and pilot testing. Our engineers will help confirm the suitable model and separation performance.
Q4: What about lubrication and maintenance?
The machine adopts thin oil lubrication (plus grease lubrication on selected models), which ensures reliable long-term operation and simple routine maintenance.
Q5: Do you support customization and what is the delivery time?
Yes, we support customization of motor power, voltage, and contact-part materials. Delivery time is 30-45 working days after deposit confirmation.
