Disc Stack Industrial Grade Centrifuge Separator

Working principle

Industrial disc centrifuge is a high-speed, continuously running precision separation equipment, mainly used for efficient separation of multiphase materials such as liquid-liquid and liquid-solid. Its core structure is a high-speed rotating drum and disc assembly. The material is quickly separated under the action of centrifugal force, and light liquid, heavy liquid and solid impurities are discharged through different outlets. It is widely used in biopharmaceuticals, food and beverages, chemicals, petroleum, environmental protection and other industries for fine separation, clarification, concentration and other process requirements.

Introduction

Disc stack separators use extremely high centrifugal forces to separate solids and one or two liquid phases from each other 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.

The selection should be based on the material characteristics (specific gravity difference, viscosity, solid content), processing capacity, separation purpose (clarification, concentration or extraction) and other factors. For liquids with high solid content or high viscosity, an automatic unloading disc centrifuge with stronger slag discharge capacity should be selected. We are a professional centrifuge manufacturer, providing equipment of multiple specifications and supporting technical consultation to ensure that customers obtain the best process matching and economic benefits.
