Patent number: 6651709Abstract: A retractable debarking block for a debarker having an enclosure to receive logs for debarking in order to vary the aggressiveness of the debarking process. The block member has a debarking surface with projecting teeth and is positionable within the enclosure of the debarker to be movable between a retracted position in which the debarking surface does not contact logs in the enclosure and an exposed position in which the debarking surface is exposed to engage logs. The block member is fittable into a rotor or drum type debarker. An actuator is provided to move the debarking surface between the retracted and exposed positions. The actuator is adapted to permit automatic movement of the debarking surface toward the retracted position if the force exerted by the logs exceeds a pre-set limit to prevent damage to the blocks and the logs. Preferably, the actuator is an airbag or telescoping cylinder operable over a range of pressures to permit adjustment of the pre-set limit.Type: GrantFiled: September 11, 2002Date of Patent: November 25, 2003Assignee: CAE Wood Products, G.P.Inventors: Michael Poropat, Peter F. Lister, Rene K. Chong

Publication number: 20030111567Abstract: The invention relates to a lifting wall for a tube mill which has a discharge means with lifting vanes in order to transport the material being ground to discharge openings by the rotary movement of the tube mill. The lifting vanes are disposed obliquely with respect to the radial direction so that the material being ground slides promptly to the centre where it is discharged through the discharge openings still below the horizontal longitudinal central plane of the tube mill.Type: ApplicationFiled: February 3, 2003Publication date: June 19, 2003Inventors: Blatton Gerhard, Hubert Grothaus, Ludger Schulte

Patent number: 6578609Abstract: An apparatus for debarking logs comprising a drum rotatable about an axis and having an inner surface and outer surface with at least one movable debarking surface adjacent the inner surface of the drum to debark logs that come into contact with the movable debarking surface at a first rate. There is at least one fixed debarking surface at the inner surface of the drum to debark logs that come into contact with the fixed debarking surface at a second rate. The movable debarking surface is movable with respect to the inner surface of the drum between an operating position to allow contact between the movable debarking surface and the logs and a retracted position to minimize contact between the movable debarking surface and the logs.Type: GrantFiled: July 12, 2002Date of Patent: June 17, 2003Assignee: Cae Wood Products G.P.Inventors: Robert Michael McNicol, Michael Poropat

Publication number: 20020158157Abstract: A simply and compactly built drive system for a tube mill is provided whose force transmission is no longer threatened by flexures and other deformations of the grinding tube. A one-piece ring gear having a diameter less than or equal to the diameter of the grinding tube is attached to the small diameter end of a discharge cone of the grinding tube.Type: ApplicationFiled: March 21, 2002Publication date: October 31, 2002Inventors: Alexander Hagedorn, Norbert Aufsfeld

Patent number: 6471148Abstract: A glass smasher is provided of the type for placement of glass articles for reduction to a particle size for reduced volumetric disposal and/or recycling purposes. Recycling may include reforming into another glass product or use as an aggregate. The glass smasher includes a rotatable barrel which may be divided into one or more internal chambers. At least a first chamber is formed having impacting means for breading and article into particles when the barrel is rotated. The first chamber may include free moving or floating smashing members such as ball bearings, bars or the like and/or attached impacting members. When an article of glass is placed in the first chamber and the barrel is rotated the article is broken into particles. These particles may be rotated and continued to impact the members until a desired particle size is achieved.Type: GrantFiled: October 27, 2000Date of Patent: October 29, 2002Assignee: Paisano Industries, L.P.Inventor: John Russell Mase, Jr.
