Industrial Decanter Centrifuge with Sealed Feed and Discharge
The Industrial Decanter Centrifuge with Sealed Feed and Discharge is designed for closed-loop solid-liquid separation where material containment, low emission, and safe operation are required.
The sealed structure prevents slurry leakage, dust release, and contact with operators, making it suitable for solvent-containing slurry, chemical materials, fine powders, and hazardous process streams.
- Solvent-containing slurry separation
- Chemical powder recovery
- Fine chemical wastewater treatment
- Pharmaceutical intermediate processing
- Battery material slurry separation
- Closed production line solid-liquid separation
- Toxic or hazardous material handling
- Explosion-risk process environments
Material Leakage Risk
Open feeding and discharge systems may cause slurry splashing, odor release, or material loss during operation.
Solvent and Hazardous Components
Some process streams contain solvents, volatile components, or harmful substances requiring closed operation.
Dust Generation
Fine powders can create dust during discharge, affecting safety and product recovery.
Strict Clean Production Requirements
Chemical and pharmaceutical industries require controlled environments and reduced operator exposure.
Continuous Automatic Operation
Production lines require stable separation without frequent manual handling.

How the Decanter Centrifuge Works
1. Sealed Slurry Feeding
Process slurry enters the rotating bowl through a closed feeding system.
2. Solid Sedimentation
Under centrifugal force, solid particles move toward the bowl wall and form a concentrated solids layer.
3. Liquid Clarification
Separated liquid remains in the inner liquid zone and moves toward the liquid outlet area.
4. Solids Conveying
The scroll continuously transports settled solids toward the discharge end.
5. Closed Separation
Separated liquid and concentrated solids are collected through sealed systems for further processing.
