How many types of industrial centrifuges are there?

There are many types of industrial centrifuges. According to the working principle, structure and application scenarios, are mainly divided into the following categories:

1. Classification by separation principle

- Filter centrifuge:

- Solid particles are trapped on the filter medium by centrifugal force, and the liquid is discharged through the filter.

- Suitable for solid-liquid separation, especially when the solid particles are large.

- Common types: three-legged centrifuge, flat plate centrifuge.

- Sedimentation centrifuge:

- Using density difference, under the action of centrifugal force, solid particles settle to the drum wall, and liquid is discharged from the top.

- Suitable for solid-liquid separation or liquid-liquid separation, especially when the solid particles are fine.

- Common types: horizontal screw centrifuge, disc centrifuge.

- Separation centrifuge:

- Mainly used for liquid-liquid separation or liquid-liquid-solid three-phase separation, using density difference to separate different liquids.

- Common types: disc centrifuge, tubular centrifuge.

2. Classification by structural form

- Table centrifuge:

- Small equipment, suitable for laboratory or small-scale industrial applications.

- Vertical centrifuge:

- The drum is installed vertically, with a small footprint, suitable for medium-scale industrial applications.

- Horizontal centrifuge:

- The drum is installed horizontally, with large processing capacity, suitable for large-scale industrial applications.

- Tubular centrifuge:

- The drum is a slender tube with high speed and high separation efficiency, suitable for high-precision separation.

- Disc centrifuge:

- The drum is equipped with a disc group, with high separation efficiency, suitable for liquid-liquid separation or liquid-liquid-solid separation.

- Screw discharge centrifuge (horizontal screw centrifuge):

- Solids are continuously discharged through a screw conveyor, suitable for materials with high solid content.

3. Classification by operation mode

- Intermittent centrifuge:

- Batch operation, suitable for small-scale or fine separation.

- For example: a three-legged centrifuge.

- Continuous centrifuge:

- It can continuously feed and discharge, suitable for large-scale industrial production.

- For example: horizontal screw centrifuge, disc centrifuge.

4. Classification by application field

- Oil-water separation centrifuge:

- It is used for the purification and dehydration of industrial oil, lubricating oil and fuel oil.

- Wastewater treatment centrifuge:

- It is used for sludge dehydration or industrial wastewater treatment.

- Food industry centrifuge:

- It is used for the separation and clarification of juice, dairy products, edible oil, etc.

- Pharmaceutical industry centrifuge:

- It is used for drug extraction, cell separation, etc.

- Chemical centrifuge:

- It is used for the separation and purification of chemical raw materials.

5. Common industrial centrifuge models

- Three-legged centrifuge:

- It has a simple structure and is suitable for small-scale solid-liquid separation.

- Plate centrifuge:

- It has good stability and is suitable for medium-scale separation.

- Horizontal screw centrifuge:

- Large processing capacity, suitable for sludge dewatering or high solid content materials.

- Disc centrifuge:

- High separation efficiency, suitable for liquid-liquid separation or liquid-liquid-solid separation.

- Tubular centrifuge:

- High speed, suitable for high-precision separation, such as biopharmaceuticals.

6. Selection suggestions

- ｓｅｌｅｃｔ the appropriate type according to material characteristics (such as solid content, particle size, density difference).

- ｓｅｌｅｃｔ intermittent or continuous type according to the processing volume.

- ｓｅｌｅｃｔ a special model according to the application field (such as food grade, or pharmaceutical grade).
