Abstract: A wood chip cracking device for use in papermaking employs closely spaced, oppositely rotating rolls which have pyramid-shaped projections on the roll surfaces. This chip destructuring apparatus is rendered readily serviceable with minimal downtime by constructing the roll surface of removable segments which are bolted to a central rotatable shaft. The segments are sized so they can be lifted by a service man. As damage to the roll surface, such as by exposure to tramp metal, is typically limited to a single segment, service and repair of the roll is expedited by permitting removal of a single damaged segment without removing the remaining undamaged segments. Each sector is bored for twelve bolts and is affixed to the central axis by twelve recessed bolts. The surface segments allow the surface to be replaced without removing the rolls from the frame of the wood chip cracking device.
