Abstract
Replaceable inserts are provided in depressions of a spiral separator wherein the inserts have surface irregularities to optimize the spiral efficiencies in separating feed stock materials. These irregularities become worn by the materials and would require replacement of the spiral, ordinarily, whereas new inserts herein greatly extend the useful life of the spiral. Also, if the feed of the spiral changes appropriate new inserts may be used to separate the changed feed. The inserts may be any shape, circular being preferred when adjustability is needed.
