TURBOSCREEN screen bowl decanter centrifuge
On standard solid bowl screen centrifuges the screening section is connected to the small diameter of the solid bowl cone and the diameter of the screen is identical. This design has the disadvantage of a low volume in the dewatering section of the centrifuge. This leads to a high solids load and the lowest centrifugal force at the solid outlet.
