LW Decanter Centrifuge
Our LW decanter centrifuge is a continuous horizontal screw sedimentation centrifuge with wide adaptability and large throughput. Featuring a horizontal coaxial bowl with differential-speed screw conveyor, the LW is purpose-built for separating suspensions with solid particle size ≥ 0.005 mm and concentration 2-40%, serving chemical, light industry, pharmaceutical, food, and environmental protection industries.

◆ Operating Principle
The LW Series horizontal screw discharge sedimentation centrifuge is a full-speed continuous settling machine with a smooth, screen-less bowl that achieves solid-liquid separation by gravitational sedimentation under a high-speed centrifugal field, where a differential-speed screw continuously pushes the sedimented cake to the cone end and discharges it while clarified liquid overflows from the large end — purpose-built for ultrafine/ultra-dilute suspensions with solid particle size ≥0.005 mm and concentration 2–40%, serving the chemical, light industry, pharmaceutical, food, and environmental protection sectors.
◆ Main Features
● Horizontal Screw Discharge, Continuous-Operation Sedimentation Equipment — Horizontal coaxial structure enables simultaneous continuous feeding/separation/discharging, running at full speed with no batch interruption.
● Differential Rotation Between Drum and Screw — Controlled by planetary-gear / hydraulic differential, adjustable 5–80 r/min differential speed to match diverse material characteristics.
● Centrifugal Force Field + Gravitational Sedimentation Mechanism — Heavy solids deposit against the drum wall under centrifugal force forming a sediment layer; the light liquid phase migrates toward the center forming an inner liquid ring.
● Continuous Feed + Internal Screw Acceleration — Material enters the screw pusher’s inner chamber via the feed pipe, accelerates, then enters the drum radially — stable, pulse-free feeding.
● Continuous Screw Conveying to Cone End & Discharge — Deposited solids are continuously pushed by the screw to the drum cone end and flung out of the machine through the slag discharge port.
● Liquid Phase Continuously Discharged via Large-End Overflow — The lighter liquid phase continuously overflows from the drum’s large-end overflow port and exits through the discharge pipe; solids and liquid discharge independently in two directions.
● Full-Speed Continuous Operation — Continuous feeding, separation, and discharging all run simultaneously at full speed; single-machine continuous capacity far exceeds batch-type centrifuges.
● Compact Structure — Horizontal coaxial design with small footprint, low foundation requirements, and short installation/commissioning cycle.
● Smooth & Stable Running — Dual-bearing support + G2.5 dynamic balance precision, vibration ≤ 4.5 mm/s RMS, suitable for unattended operation.
● Strong Material Adaptability — Handles suspensions with solid particle size ≥ 0.005 mm and concentration 2–40%, serving chemical / light industry / pharmaceutical / food / environmental protection sectors.
● Large Production Capacity — Single-machine throughput from several m³/h up to hundreds of m³/h, far exceeding traditional filter centrifuges of equivalent size.
● Convenient Maintenance — Modular design allows individual disassembly and servicing of key components (bearings / differential / screw), minimizing downtime.
