Classification standard for centrifuges

Divided by Fr value of separation factor
Centrifuges can be divided into the following types:
1. Constant speed centrifuge
Fr ≤ 3500 (usually 600-1200), this type of centrifuge has a lower rotational speed and a larger diameter.
2. High speed centrifuge
Fr=3500~50000, this type of centrifuge has a higher rotational speed, usually with a smaller drum diameter and a longer length.
3. Ultra High Speed Centrifuge
Fr>50000, due to the high speed (above 50000 r/min), the drum is made into a slender tube type.
The separation factor Fr refers to the ratio of the centrifugal force exerted on the material in the centrifugal field to the gravity exerted on the material in the gravitational field.
Divided by operation method
Centrifuges can be divided into the following types:
1. Clearance centrifuge
The processes of feeding, separation, washing and slag unloading are all intermittent operations, and the slag is unloaded by manual, gravity or mechanical methods, such as tripod and top suspended centrifuges.
2. Continuous centrifuge
The processes of feeding, separation, washing, and slag unloading can be carried out automatically with gaps or continuously.
