Abstract

A separating drum, having a multiple of cylindrically shaped separating elements, which are arranged parallel to the axis of rotation of the drum is provided with an arrangement by which a single part can be moved to form an adjustable separating slot. The separating drum includes separating elements which are firmly connected in pairs respectively by at least one carrier element, which is provided on one of the front faces of the separating elements. The carrier element can be rotated around the axis of a cylindrically shaped separating element situated on the circumference of the drum. Further, an adjusting wheel is provided which can be driven by a circulating adjusting element for setting the separating slot, the adjusting wheel having an axis of rotation on at least one of the front faces of the stationary separating element.

Dependent claims

A rotatable separating drum having cylindrically shaped separating elements each having a longitudinal axis arranged parallel to an axis of rotation of the drum comprising

(a) at least one carrier element, pivotably affixed to the separating drum, for firmly connecting adjacent cylindrically shaped separating elements in pairs, the at least one carrier element having an axis of pivot coaxial with the longitudinal axis of one of the pair of separating elements connected by the at least one carrier element, to form a rotatable separating element which is rotatable about the longitudinal axis thereof and a pivotable separating element which is pivotable about the axis of rotation of the rotatable separating element;
(b) an adjustable separating slot formed between adjacent pairs of connected separating elements;
and
(c) an adjustment wheel affixed to at least one of the carrier element and the rotatable separating element, the adjustment wheel having an axis of rotation coaxial with the axis of rotation of the at least one carrier element;
and
(d) a drive means for rotatably driving the adjustment wheel to set the separation slot.
