First, according to the separation factor Fr value
Centrifuges can be divided into the following types:
1, constant speed centrifuge
Fr ≤ 3500 (generally 600 ~ 1200), this centrifuge has a lower rotation speed and a larger diameter.
2, high speed centrifuge
Fr = 3500 ~ 50000, the speed of this centrifuge is higher, the diameter of the drum is generally smaller, and the length is longer.
3. Ultra-high speed centrifuge
Fr>50000, because the rotation speed is very high (50000r/min or more), the drum is made into a slender tube type.
The separation factor Fr refers to the ratio of the centrifugal force of the material in the centrifugal force field to the gravity of the material in the gravity field.
Second, according to the operation mode
Centrifuges can be divided into the following types:
1, gap centrifuge
The processes of feeding, separating, washing and unloading slag are all gap operations, and manual, gravity or mechanical methods are used to remove slag, such as three-legged and upper-suspension centrifuges.
2, continuous centrifuge
The processes of feeding, separating, washing and unloading slag are carried out automatically and continuously.
Third, according to the method of unloading slag
The centrifuge can be divided into the following types:
1, scraper discharge centrifuge
The process is indirect and the operation is automatic.
2, piston pusher centrifuge
The process is semi-continuous and the operation is automatic.
3, screw discharge centrifuge
The process is continuous and the operation is automatic.
4, centrifugal force discharge centrifuge
The process is continuous and the operation is automatic.
5, vibration discharge centrifuge
The process is continuous and the operation is automatic.
6, the unloading centrifuge
The process is continuous and the operation is automatic.
Fourth, according to the purpose of the process
Centrifuges can be divided into: filter centrifuges, decanter centrifuges.
Fifth, according to the way of installation
It can also be divided into vertical, horizontal, inclined, overhang and three-legged.
6. According to national standards and market share
For the following four
1. Three-legged centrifuge
2. Horizontal screw centrifuge
3. Disc separator
4. Tubular separator
