Centrifuge program features

Contents of this chapter

This chapter describes the operational sequence of Centrifuge drive and also includes the 
important functions within the control program that are specific to the Centrifuge 
application.

Centrifuge control program

Centrifuge operating principle

Figure 3. Centrifuge operation

The Centrifuge operation is based on the principle of centrifugal force. The Centrifuge 
accelerates to a pre determined filling speed and then the feed input is initiated. As the 
centrifugal force drives the feed through filter media and perforated basket wall, a cake 
builds up on the filter media. The liquid is removed through an outlet. The retained solid 
particles are accelerated to spinning speed, after which the centrifuge decelerates to 

Basket

Input feed

Liquid output

Solids output
