Q1: What is an LW decanter centrifuge?

An LW decanter centrifuge is a type of horizontal, continuous solid-liquid separation machine widely used in industrial processes.

It separates solids from liquids by using high centrifugal force instead of gravity, making it much faster and more efficient than traditional settling tanks or filters.


Q2: How does an LW decanter centrifuge work?

Inside the centrifuge, separation takes place in a horizontal rotating bowl equipped with a screw conveyor.

The process works as follows:

  1. The material enters the bowl through a stationary inlet tube

  2. The bowl rotates at high speed, generating strong centrifugal force

  3. Solids quickly settle on the inner wall of the bowl

  4. The conveyor rotates in the same direction as the bowl but at a slightly different speed

  5. Solids are pushed toward the conical end and discharged continuously

This design makes LW decanter centrifuges ideal for non-stop industrial operation.

Q3: What industries commonly use LW decanter centrifuges?

LW decanter centrifuges are extremely versatile and are widely used as sludge dewatering decanter centrifuges in:

  • Industrial and municipal wastewater treatment

  • Oil & gas drilling mud and fluid control

  • Starch, protein, and food processing

  • Fruit juice clarification and vegetable oil extraction

  • Mineral processing, coal washing, pigments, and chemicals

Their ability to handle high solid loads and abrasive materials makes them suitable for demanding applications.


Q4: What makes LW decanter centrifuges reliable for heavy-duty operation?

LW decanter centrifuges are designed for stability, durability, and safety:

  • Vertical base design with symmetrical motor arrangement for low vibration

  • Bowl and conveyor made from stainless steel or duplex steel

  • Wear resistant decanter centrifuge construction using tungsten carbide or ceramic protection

  • Dual motor, dual frequency control with stepless speed adjustment

  • Multiple safety protections including overload, vibration, and temperature monitoring

These features ensure long service life even under harsh conditions.


Q5: How is wear protection handled in LW decanter centrifuges?

Wear protection is critical in solid-heavy processes.

LW decanter centrifuges use:

  • Tungsten carbide or ceramic-lined scroll flights

  • Wear-resistant strips on the bowl inner wall

  • Replaceable carbide tiles at solid discharge ports

This design significantly reduces maintenance costs while maintaining separation efficiency.


Q6: Why choose an LW standard type decanter centrifuge?

The LW standard type decanter centrifuge uses a labyrinth seal design that is simple, reliable, and easy to maintain.

It offers:

  • Continuous and stable operation

  • Simple structure with easy replacement of wear parts

  • Wide application scope across industries

For companies looking for a proven, cost-effective solution, LW decanter centrifuges provide an excellent balance of performance and durability.
