Key Features:

Key Feature 1 — High Efficiency & Low Operating Cost

Short full-speed cycle and high-G dewatering deliver strong throughput and stable cake moisture performance. Optimized wash-water distribution reduces water consumption while maintaining washing effectiveness. Direct-drive / optimized mechanical design helps lower maintenance workload.

Key Feature 2 — Closed, Corrosion-Resistant Process Housing

Fully enclosed casing reduces odor and aerosol escape and supports cleaner, safer operation. Corrosion-resistant selections are available for hot, mildly acidic and abrasive gypsum slurries.

Key Feature 3 — Multi-Stage Washing for Chloride/Salt Control

Staged washing (often in counter-current mode) improves removal of soluble salts and chlorides. Final targets depend on feed properties and wash scheme; we propose realistic targets after reviewing your data.

Key Feature 4 — Fully Automatic 24/7 Operation (PLC/DCS Ready)

PLC/DCS-based control with interlocks for feed, vibration, torque/cake load, and cover position supports continuous unattended operation and easy integration into plant FGD control systems.

Key Feature 5 — Compact Skid-Mounted Layout

Centrifuge, filtrate collection, wash-water distribution and utility piping are integrated on a single skid, reducing civil works and site installation time while simplifying inspection and maintenance.

Process Characteristics (Technical Analysis):

(1) Excellent dewatering + effective washing: High-G cake formation plus staged washing enables efficient removal of soluble impurities with stable dewatering results (final performance depends on PSD, solids wt% and wash ratio).

(2) Robust mechanical design for harsh slurry: Options for corrosion/abrasion resistance to match chloride level, temperature and solids content.

(3) Automation & safety: Interlocked operation reduces operator exposure and ensures stable continuous running.

(4) Cost efficiency: Optimized drive and acceleration profile help reduce mechanical loss and maintenance frequency.

(5) Skid package concept: Factory pre-assembly and testing shortens commissioning time and reduces site risk.

Typical Industries and Products:

Power generation (coal/biomass): limestone–gypsum wet FGD gypsum dewatering and washing

Metallurgy & smelting: scrubbing by-product gypsum-type slurries, complex salt systems

Chemical & fertilizer: by-product gypsum requiring intensive washing and stable moisture control

Construction materials: gypsum slurry conditioned for downstream processing or sale

Working Principle:

During operation, FGD gypsum slurry is fed into the rotating basket lined with filter cloth. Under centrifugal force, solids build up to form a cake while liquid passes through as filtrate. Wash liquor is distributed in one or multiple stages (often counter-current) to reduce soluble salts and chlorides. The basket then accelerates to dewatering speed to reach the target moisture. Finally, the machine decelerates to peeling speed and a hydraulic scraper peels the cake off the cloth; solids discharge automatically through the chute. Optional flushing/CIP can be programmed to maintain stable operation and cleanliness.
