ABSTRACT Four different roll designs were evaluated on a test bench roll crushersplitter to determine feeding and crushing efficiencies. For each design, different gap settings for the primary and secondary rolls were tested at two hydraulic cylinder pressures on the primary crush roll to determine their ability to crush andor feed tree bolts.
