  • Maximizer for gravity separators
    Patent number: 6398035
    Abstract: A gravity separator with improved efficiency comprising a gravity table with pins at the feed area and a flow channeler. The pins create space in the bed of material to be separated which increases stratification of the weight fractions. The flow channeler creates flow paths of the fractions which do not cross and therefore the fractions do not slow each other from feed to discharge.
