Vertical Chemical Decanter Centrifuge
,Decanter Centrifuge with PLC Control System
,High Motor Power horizontal decanter centrifuge
The Industrial Decanter Centrifuge for Powder Washing Lines is designed for continuous solid-liquid separation in powder washing and purification processes.
It is suitable for industries requiring continuous washing, dewatering, impurity removal, and recovery of valuable powder materials, including salt processing, mineral purification, chemical powders, food ingredients, and industrial crystallization processes.
- Washed salt powder purification
- Industrial salt refining and purification
- Mineral powder washing
- Chemical powder washing and recovery
- Activated carbon washing
- Catalyst powder purification
- Pigment and inorganic powder processing
- Fine chemical crystal washing
- Battery-material powder cleaning
- Pre-treatment before drying or packaging
High Moisture Content
Washed powders retain residual liquid after washing.
Efficient centrifugal dewatering helps reduce drying energy consumption.
Fine Powder Loss
Fine particles may remain suspended in washing liquid.
Optimized separation improves powder recovery and reduces material loss.
Difficult Solid-Liquid Separation
Fine particles with slow settling behavior are difficult to separate by gravity.
High-speed centrifugal separation provides continuous and efficient separation.
High Water Consumption
Traditional washing processes may require large amounts of water.
Optimized washing and separation help improve water utilization.
Product Purity Requirements
Powder washing requires effective removal of soluble impurities and contaminants.
Controlled separation helps maintain stable product quality.
Abrasive Material Wear
Salt crystals, minerals, and hard particles may cause equipment wear.
Wear-resistant materials and protective designs can be configured.

How the Decanter Centrifuge Works
1. Powder Slurry Feeding
The washed powder slurry enters the rotating bowl through a controlled feeding system.
2. High-Speed Solid Sedimentation
Under centrifugal force, solid particles move toward the bowl wall and form a compact solids layer.
3. Washing and Liquid Separation
Clean washing liquid helps remove soluble impurities while clarified liquid moves toward the liquid outlet zone.
4. Continuous Solids Conveying
The scroll continuously transports separated powder solids toward the conical discharge end.
5. Separate Discharge
Washed powder and clarified liquid are discharged continuously through separate outlets.

Main Advantages
High-Efficiency Powder Washing
The decanter centrifuge enables continuous separation of washed powder solids and process liquid, helping remove soluble impurities and improve product purity.
Effective Moisture Reduction Before Drying
High centrifugal force removes residual washing liquid from powder materials, reducing downstream drying load and improving overall process efficiency.
Valuable Powder Recovery
The optimized separation process helps recover fine powder particles from slurry, reducing material loss during washing and clarification.
Continuous Washing and Dewatering Process
The decanter centrifuge integrates feeding, separation, washing, and solids discharge into one continuous operation, reducing manual handling and production interruptions.
Customized Wear-Resistant Design
For abrasive materials such as salt, mineral powders, and chemical crystals, wear-resistant scrolls, liners, and material options can be configured to extend service life.
Please provide:
- Powder type and composition
- Particle size distribution
- Solid concentration (wt% or vol%)
- Washing liquid type and volume
- Required washing efficiency
- Feed capacity (m³/h or t/h)
- Required final moisture content
- Abrasiveness of solid particles
- Operating temperature
- Corrosion requirements
Can a decanter centrifuge wash and dewater powder at the same time?
Yes. A decanter centrifuge can combine liquid separation and washing processes, depending on the process design and washing requirements.
Is it suitable for salt powder washing?
Yes. Decanter centrifuges can be used for continuous separation and washing of salt slurry, especially in processes requiring high throughput and reduced water consumption.
Can it handle fine powder particles?
Yes, but performance depends on particle size, density difference, viscosity, and solids concentration.
What is the difference between a decanter centrifuge and a filter for powder washing?
A decanter centrifuge provides continuous operation, automatic solids discharge, and better suitability for high-capacity production lines, while filters are often batch-operated.
Can the centrifuge be customized for abrasive powders?
Yes. Wear-resistant liners, hard alloy protection, and optimized scroll designs can be configured according to material characteristics.
