Getting Aggressive with Secondary Grinding

Typical applications include bull screen rejects processing through a ½” or ¾” rectangular holed screen.


When the secondary grinding involves bull screen rejects in the harsh papermaking environment, the Montgomery Bull Screen Rechipper comes prepared for the job.


In addition to the aggressive cut and wear liners in the cutting chamber, the bearings are sealed, hose bibs are provided for flushing, stainless steel is welded to the rings and the housing is covered in a special anti-corrosion epoxy.


For the ultimate in corrosion resistance, the housing, wear liners, hardware, rings, teeth and screen can all be manufactured out of stainless steel.
