Abstract
A chip screening system has a primary screening station for dividing an incoming flow of chips into a first acceptable fraction and a second fraction having acceptable chips and also both oversized and overthick chips. The second fraction is directed to a second screening station where the incoming flow will again be fractionated into an acceptable flow being screened primarily according to thickness and a second fraction being composed of oversized and overthick chips. The second fraction is then directed to a size reducing station.
