Abstract: The combined centrifugal separator with supplementary work units is an autonomous stationary or mobile complex apparatus, which is related to the separation of non-uniform granular or fibrous product, such as manure pulps, fruit pulps, sugar contained pulps, pulps for the medicine, etc., from the liquid in which it is carried. The screen, the screen scraper, and the driving shaft, which has the screw, the crusher and the mixer located on it, all have one common axis. However, all three rotate with different speeds around it. They are connected to one motor, and have a transmission system using pulleys and gears. Part of the liquid remainder may be used for internal recycling.
