Bar Screen with Bars of Staggered Height

摘要

A bar screen system comprising twa sets of interleaved bars. In each sat, the height of the individual bars is staggered so every third is higher than the other bars, which are the same height. The bars one driven such tha t the bars in one set are approximately 180.degree. behind the other set in their respective predetermined paths of movement, resulting in a tipping and agitation action which tends to present the wood chips loaded at a high rate onto the bar screen in their thickness dimension to the slots between adjacent bars.
