With the improvement of the slag removal mechanism, a fully automatic centrifuge with intermittent operation was presented in the 1930s. The fully automatic centrifuge was also developed due to the completion of automatic control. At present, automatic centrifuges have been used in many departments such as metallurgy, chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipping. The industrial automatic centrifuge was born in Europe. In the middle of the 19th century, it was presented with a three-legged automatic centrifuge for textile dehydration and an upper-suspension automatic centrifuge for separating crystal sugar from the sugar factory. These are very early. Automatic centrifuges are batch operated and manually drained.

How Automated Centrifuges Work: Industrial automatic centrifuges are structured and separated, It can be divided into three categories: filtration automatic centrifuge, sedimentation automatic centrifuge and separator. The fully automatic centrifuge has a cylinder that rotates at a high speed about its own axis, called a drum, which is typically driven by an electric motor. After the suspension (or emulsion) participates in the drum, it is rapidly driven to rotate at the same speed as the drum, and the groups are separated under the effect of centrifugal force, and separated and discharged. Generally, the higher the rotational speed of the drum, the better the separation effect.

The principle of centrifugal separators is centrifugal filtration and centrifugal sedimentation. Centrifugal filtration is a centrifugal pressure that causes the suspension to occur under a centrifugal force field. The effect is on the filter medium, so that the liquid passes through the filter medium to become a filtrate, and the solid particles are trapped on the outer surface of the filter medium, and then the liquid-solid separation is completed.

At present, when the control system opens the feed valve, the treated suspension reaches the full-speed running disc from the feeding tube, and uniformly filters the filter medium on the inner wall of the drum under the effect of centrifugal force. Above, the suspension at this time is in a liquid phase separated by filtration, and is filtered out through a small hole in the drum through the filter medium under the effect of centrifugal force, and is discharged from the drain pipe by the inner wall of the casing and the chassis. The solid phase particles remain on the filter medium, and after washing and dehydration, when the separation request is reached, the unloading mechanism is discharged from the discharge port at the bottom of the body.
