Abstract
A vertical centrifuge comprises a housing provided with a cover. A centrifuge drum is arranged to be rotatable in the housing and has an upper feed opening and a lower discharge opening.

The holding arrangement comprises means for the rotation of the shaft.
Claims10
A vertical centrifuge comprising
- a. a housing provided with a cover which closes its upper end;
- b. a centrifuge drum mounted in the housing for rotation about a vertical axis and having a top inlet opening and a bottom discharge opening;
- c. means for leading material through the cover and the inlet opening to a region of the drum located at one side of said axis;
- d. stripping means in said region for separating centrifuged material from the drum and thereby facilitating its discharge through the discharge opening;
- e. a shielding wall located inside the drum above the discharge opening and extending around only a portion of the circumference of that opening;
- f. a shaft extending vertically into the drum through the cover and the inlet opening and connected with the shielding wall;
- and
- g. means for rotating the shaft between positions in which the shielding wall is disposed at opposite sides of said axis,
- h. the shielding wall serving selectively to impede passage of material from said region to the discharge opening when positioned at the same side of the axis as that region, and to permit free passage of material from said region to the discharge opening when positioned at the opposite side of the axis.
