Patent number: 6883737Abstract: The device comprises a stator with gear rings and a rotor with teeth meshing with the teeth of the stator. Between arms of the rotor protrudes a guiding funnel that concentrates the material flow coming in from above to the central area of the container. The outer surface of the guiding funnel defines an annular gap throttling the material flow. At the rotor, a feed screw is provided that feeds towards the working region of the device. The guiding funnel retains the product in the active region of the device and the feed screw generates an increased material pressure in the center.Type: GrantFiled: August 23, 2002Date of Patent: April 26, 2005Assignee: Cavitron v. Hagen & Funke GmbHInventors: Klaus Fisch, Jens-Uwe Wichmann

Patent number: 6824089Abstract: A machine for collecting and reducing wood including a prime carrier; a debris collector operatively attached to the prime carrier; a shredder assembly attached to the prime carrier, the shredder assembly having an input and an output; a storage bin for holding reduced wood, the storage bin attached to the prime carrier; and a conveyor adapted to move reduced wood from the output of the shredder assembly to the storage bin. The prime carrier may also have a universal adapter of substituting attachments. A variable torque, drum shredder for reducing wood. The drum shredder includes a housing; a tapered cutting drum rotatably mounted within the housing; an anvil; at least one cutting blade disposed about an outer surface of the cutting drum to provide a compound cutting angle; and a drive connected to the cutting drum. A shredder having a discharge assembly adapted for accommodating discharged material with at least two major discharge streams with at least two major discharge directions.Type: GrantFiled: February 16, 2002Date of Patent: November 30, 2004Inventors: Thomas R.

Publication number: 20040144875Abstract: A segment for a rotary disk refiner that has a refining surface offset to compensate for deflection of the segment that occurs during refiner operation. In one preferred embodiment, the refining surface overlying each segment overhang is offset to compensate for deflection that occurs in the region of the overhang during refiner operation. Other regions of the refining surface can also be offset to compensate for deflection. In another preferred embodiment, a mount that extends outwardly from the backside of a segment has a hollow therein to reduce segment mass to reduce refining surface deflection. In a method of making a deflection compensating segment, the location and magnitude of each region of deflection is analytically or experimentally determined and the refining surface is formed with a corresponding offset in each deflection region.Type: ApplicationFiled: January 8, 2001Publication date: July 29, 2004Applicant: J & L Fiber Services, Inc.Inventor: Ola M.

Patent number: 6587803Abstract: A sensor, sensor disk, sensor measurement correction system, and method used in measuring a parameter in the refining zone. The sensor includes a spacer that spaces its sensing element from the disk. In one preferred embodiment, the spacer is made of an insulating material that insulates the sensing element from the thermal mass of the disk to prevent the thermal mass from affecting sensor measurement. The sensor includes a housing carried by the spacer that, in turn, carries the sensing element. Where the sensing element is a temperature sensing element, the housing is thermally conductive and the housing and spacer enclose the sensing element. Each sensor is disposed in the refining surface, preferably in its own separate bore in the disk and flush with or below axial refiner bar height. Signals from one or more sensors are processed by a processing device linked to a module containing calibration data that is applied to make sensor measurements more accurate.Type: GrantFiled: November 6, 2001Date of Patent: July 1, 2003Assignee: J & L Fiber Services, Inc.Inventor: Ola M.
