Replaceable liner for centrifuge sieve

Abstract

A centrifuge sieve has a support drum rotatable about an axis, a pair of axially spaced rings secured in the drum and centered on the axis, and an array of like sieve bars having radially inner surfaces defining a body of revolution centered on the axis. The bars each have opposite ends each in turn having two formations radially outside the body. One of these formations engages over and radially inside the respective ring and the other formation engages radially outside and under the ring. Thus the rings lie outside the body and underneath lateral projections serving circumferentially to space adjacent bars apart. The upper surfaces of the lateral spacing projections lie below the radial inner surfaces of the bars and at least one end of each bar is chamfered to reduce the change of material catching on the bar.
