The Decanter Centrifuge for Nickel Cobalt Manganese Hydroxide Slurry Dewatering is designed for continuous solid-liquid separation, NCM precursor recovery, slurry thickening, and process-liquid clarification.

It is suitable for NCM hydroxide precipitation slurry, washing slurry, classification overflow, off-spec material recovery, and battery-material wastewater treatment.

The centrifuge separates nickel cobalt manganese hydroxide particles and other suspended solids from the liquid phase. Corrosion-resistant materials, wear protection, and contamination-control configurations can be selected according to the process conditions.

Particle Size

Fine NCM hydroxide particles may settle slowly. Particle-size distribution and settling tests should be checked before selection.

Slurry Concentration and Viscosity

High solids concentration or viscosity may reduce processing capacity. Stable feeding is important for consistent separation.

Liquid Composition

The liquid phase may contain ammonium salts, sulfates, alkalis, complexing agents, or residual metal ions. The complete composition should be provided for material selection.

Product Purity

NCM precursor production may have strict contamination limits. Wetted materials and wear-resistant components should be selected carefully.

Washing and Downstream Process

The required discharge concentration depends on whether the solids are sent to further washing, filter pressing, drying, or reprocessing.

High NCM Precursor Recovery

High centrifugal force continuously recovers valuable nickel cobalt manganese hydroxide particles.

Stable Slurry Thickening

Adjustable operating parameters maintain stable separation under changing feed conditions.

Lower Downstream Load

Pre-thickening reduces the liquid volume entering filter presses, washers, or dryers.

Process-Liquid Recovery

Clarified liquid can be recycled or transferred to further metal recovery and treatment.

Purity and Corrosion Control

Customized materials and internal protection support corrosive and high-purity battery-material processes.

Please provide:

• NCM composition and process stage
• Particle size and solids concentration
• Slurry density, viscosity, pH, and temperature
• Liquid composition and purity requirement
• Required capacity and recovery target
• Downstream washing, filtration, or drying process
