Dewatering decanter for chemical and mineral processing

Maximize efficiency in liquid-solid separation, ensuring optimal clarification and dewatering in high-demand chemical and mineral processing operations.

Separates and Dewaters Liquids and Solids

The Dewatering Decanter crudMaster from GEA is a specialized centrifuge designed to streamline liquid-solid separation processes within chemical and mineral processing industries. This deep-pond, 3-phase decanter utilizes a solid-wall bowl featuring a cylindrical section for effective liquid clarification and a conical section for drying solids. Solids are propelled onto the inner bowl shell by centrifugal forces and transported by the scroll to the discharge, while liquid phases are managed through a centripetal pump and drain tubes.

Ideal for various industries including environmental services and food processing, it handles diverse product types—liquid, solid, and slurry—through continuous, high-speed operations. The crudMaster offers significant throughput advantages, supported by a GEA summationdrive, which ensures high differential speeds and increased torque for processing substantial solid loads efficiently.

Crafted with high-alloyed duplex and super duplex stainless steels, as well as Hastelloy C276, the equipment provides superior corrosion resistance. It complies with stringent ATEX standards, guaranteeing explosion protection with an inert gas atmosphere during operation. Additionally, its compatibility with CIP systems facilitates seamless cleaning and maintenance.

Engineers can benefit from customizable settings, including frequency-controlled motor adjustments for differential speeds, ensuring the unit adapts to specific operational demands. The crudMaster’s capabilities make it a valuable component for any high-demand processing line, offering robust performance and integration possibilities.
