Disc Stack Separator

Disc Stack Separator

Working principle

The disc stack separator operates by swiftly separating solid and liquid components using high-speed centrifugal force. Also referred to as a disc centrifuge or conical plate centrifuge, it falls under the category of vertical centrifuges. Powered by a motor, the disc separator rotates rapidly. Within its bowl, a series of nested disc-shaped components, commonly called discs, create small gaps between them for the centrifugal sedimentation of materials.

The suspension (or emulsion) to be processed is introduced into the disc separator's bowl through the feed pipe. As the suspension (or emulsion) traverses the gaps between the discs, solid particles (or droplets) settle on the discs due to centrifugal forces, forming a sediment (or liquid layer). The sludge moves along the disc's surface, separating from it and accumulating in the inner bowl where the diameter is larger. The separated liquid exits the bowl through the liquid outlet.

In the case of a 3-phase disc separator, two centripetal pumps are situated inside to discharge the two immiscible liquid phases with different densities. The role of the discs in the disc separator is to reduce the settling distance of solid particles (or droplets) and increase the effective settling area of the bowl, significantly enhancing the production capacity of the disc separator. The accumulated solids in the bowl can be discharged through the automatic slag discharge mechanism without halting the machine. Utilizing the disc separator enables the realization of solid-liquid-liquid 3-phase separation or solid-liquid 2-phase separation.

GN Disc Stack Separator Features

All components that come into contact with the material are crafted from high-grade stainless steel, effectively minimizing chemical interactions between the separated material and the surface of these components. The centripetal pump of varying sizes facilitates the output of separated light and heavy phase liquid materials. This machine employs upper feeding, resulting in lower inlet pressure on the material.

For power transmission, a combination of hydrodynamic coupling and a pair of helical gears or belt drive is utilized, ensuring stable speed increase and the capability for overload protection. The slag discharge action of the sliding piston is automatically regulated by a PLC fully automatic control cabinet equipped with safety protection devices. This setup offers high-level automation, strong adaptability for process adjustments, convenient tuning, low noise levels, and an effective separation outcome.

The centripetal pump system is professionally designed, featuring stable output pressure, a broad adjustment range, and user-friendly operation.
