2-phase separating decanter for chemical and mineral processing

Ensure precise separation and optimal moisture control in your chemical and mineral processes with this robust decanter centrifuge, designed to efficiently handle complex slurry compositions and enhance product consistency.

Separates and Classifies Chemical and Mineral Slurries

The 2-Phase Separating Decanter cutMaster from GEA is a robust industrial centrifuge meticulously engineered for dewatering and classification in chemical and mineral processing industries. This equipment distinguishes itself with a solid-wall bowl design featuring a cylindrical section for efficient liquid clarification and a conical section for drying solids. With its adaptable GEA summationdrive, the centifuge excels in processing high solid capacities through dynamic differential speed and torque adjustments.

Capable of operating in continuous and automated settings, this decanter is integral to the separation and classification of materials such as titanium dioxide pigments, sodium carbonate, and kaolin. It effectively handles a diverse range of solid, liquid, slurry, and cake product types, offering customizable throughput options aligned with specific production needs.

Built to withstand rigorous industrial conditions, the equipment incorporates high-alloyed duplex and super duplex steels or Hastelloy C276, ensuring superior corrosion resistance. The decanter is CIP-compatible for seamless cleaning, reducing downtime significantly. GEA’s unit meets stringent ATEX standards, offering explosion protection with inert gas blanketing, and is suitable for use in temperatures up to 130°C. Integration into existing production lines is streamlined with its frequency-controlled motor and energy-efficient design, saving up to 20% on energy consumption.
