Abstract
A point of sale wood chip classifier includes apparatus for receiving and discharging unclassified wood chips onto a longitudinally extending downwardly angled trough-shaped vibratory classification bed which includes a plurality of rotating disks for promoting tumbling of the chips toward an overflow end, the bed including openings between the disks defining a plurality of classification zones of increasing size along the bed in the downhill direction. A plurality of collection bins are located below the classification zones for receiving the classified chips, the classification bins being carried on respective load cells which signal the individual weights of a sample to a microcomputer for calculation of totality of chips and percentages of each classified component.
