Disc Separator, Disc Stack Centrifuge Separator

 

Disc Separator Introduction

 

Disc centrifuge, also known as disc separator, is a mechanical device that uses a high-speed rotating disc system to achieve efficient separation between liquid and solid particles or two immiscible liquids. This centrifuge is particularly suitable for processing materials that are difficult to separate by traditional methods, such as suspensions containing tiny solid particles, emulsions, and liquid mixtures with similar density but immiscible.

 

Disc Separator Working Principle

 

The disc centrifuge is mainly composed of a drum, discs, transmission device, motor, and feeding and discharging system. The drum is equipped with a set of discs that overlap each other, with a small gap between the discs. When the material enters the drum, the solid particles or liquids of different densities in the material will be quickly separated under the strong centrifugal force generated by high-speed rotation. The solid particles or heavy liquid will be deposited on the inner surface of the disc and slide along its surface to the inner wall of the drum, and then discharged through the slag discharge port; while the light liquid or clarified liquid will be discharged from the other end of the drum.

 

Disc Stack Separators use extremely high centrifugal forces to separate solids and one or two liquid phases from one another in a single, continuous process. When the denser solids are subjected to this force, they are pressed outwards towards the walls of the rotating bowl, while the less dense liquid phase forms a concentric inner layer. The area where these two different liquid phases meet is called the interface location. This can be easily varied to ensure that the separation occurs with maximum efficiency. Insertion of special plates (“disc stacks”) provides additional surface settling area, which helps to greatly speed up the separation process. It is the special configuration, shape and design of these plates that enables the Disc Stack Centrifuge to continuously separate a wide range of different solids from one or two liquids. The concentrated solid phase formed by the particles can be removed continuously, intermittently or manually, depending on the centrifuge type and the amount of solids involved in the specific application.
