CALIBRATION TECHNIQUE FOR THE DRUM STYLE CHIP THICKNESS CLASSIFIER

• The drum style chip thickness classifier* is a commonly used machine to describe the size distribution of wood chips destined for consumption in the pulp and paper industry.
• This document describes a preferred procedure to determine the number of revolutions the stepper motor should be instructed to turn so the classifier will accurately separate wood chips at a set of defined sizes.
• The objectives are:
  • Identify machines that are in need of repair due to wear on drum components,
  • Provide a calibration technique that can be used by various operators so they will achieve Like results,
  • Provide a calibration technique that can be used on various classifiers so they will achieve like results, and
  • Lessen the difference seen among different classifiers that classify similar material.
