Abstract
A device comprising two coaxial drums (22, 24) is proposed in order to separate and then proportion objects of different sizes. The objects are introduced into one end of the inner drum consisted mainly of a coil (32) wound in a spiral. Large objects are retained in this inner drum and are routed when in rotation. Small objects drop into the outer drum (24) and are routed to its other end when it is driven in rotation. Small objects drop into the outer drum (24) and are routed to its other end through a spiral inner header (50) when it is driven in rotation. Thus objects such as hulls and end pieces obtained after cutting irradiated nuclear fuel assemblies can be separated and then proportioned.
