Patent number: 7946513Abstract: The present invention regulates the delivery of feedstock to the fragmentation zone in a gravity-fed comminuting machine and reduces the ejection of feed materials by means of a rotating cylinder located at an offset position above the rotor. Rotationally mounted on an axis parallel to and above, but offset from, the axis of the rotor, this cylinder serves primarily as a striking surface, or anvil. The continual rotation of the anvil, in the opposite rotational direction as the rotor and with much slower rotational speed, assists in agitating the feed material, alleviating the problems of feed chute obstructions and feed aggregation. The cylinder forces the feed materials into contact with the rotor teeth through continuous rotation and provides a novel tooth design to improve efficacy and reduce wear.Type: GrantFiled: October 24, 2008Date of Patent: May 24, 2011Inventors: Jamey O.

Patent number: 7581691Abstract: The novel rotor for a bale processor comprises a number of plate sections that extend radially outward from a rotor axis with bale disintegrators mounted on outer edges of the rotor plate sections for bale disintegration during rotor rotation. The rotor may have four or at least four rotor plate sections. One such rotor includes a first rotor plate having a predetermined width W, length L and thickness T, second and third rotor plates each having a thickness T, a length L and a width approximately equal to (W/2?½T). The second rotor plate is fixed to one side of the first rotor plate and the third rotor plate is fixed to the other side of the first rotor plate to form a symmetrical rotor having a length L and an X-cross-section. The disintegrators include a number of pairs of flail supports fixed to outer edges of the rotor plates and a flail pivotally mounted to each of the flail support pairs.Type: GrantFiled: June 23, 2004Date of Patent: September 1, 2009Assignee: Bridgeview Mfg. Inc.Inventors: Raymond Helmeczi, Dan McCarthy

Publication number: 20090206186Abstract: The invention relates to processing apparatus and methods and in particular, but not exclusively, to an apparatus that may be used to process a wide variety of feed materials by one or more of milling or grinding, mixing, blending, separation, drying and sterilisation. In a preferred embodiment there is provided a feed material processing apparatus (1) comprising: a chamber (2); at least one inlet (4) in flow communication to an upper region of the chamber (2); a rotor (3) located within the chamber (2) that is rotatable about a substantially vertical axis by a rotation drive (11), wherein the rotor (3) promotes a circulatory flow of feed material and/or gas within the chamber (2); at least one outlet (5) in flow communication from a lower region of the chamber (2). Preferably the apparatus (1) comprises at least one feature located laterally on the rotor (3) to promote the circulatory flow.Type: ApplicationFiled: January 14, 2005Publication date: August 20, 2009Inventors: Michael Joseph Morrison, Axel Guenther Andre

Publication number: 20090140089Abstract: An impact crusher includes a crushing chamber, a rotor mounted in the crushing chamber, and an apron having an impact surface, said apron being movably positioned within the chamber. The apron is pre-loaded to oppose forces generated within the crushing chamber. The apron is free to move away from the rotor in the event that the forces generated within the chamber exceed a predetermined threshold. During normal use, the apron is suspended within the chamber against a mechanical stop, and the apron is free to return to its initial suspended position after the removal of uncrushable material from the chamber.Type: ApplicationFiled: December 1, 2008Publication date: June 4, 2009Applicant: TEREX PEGSON LIMITEDInventor: Ian Boast

Publication number: 20090114752Abstract: The invention relates to an apparatus and method for conditioning materials for processing such as materials used in a recycling process. The invention includes a conditioning section comprising a drum associated with teeth. The end of the drum is rounded to prevent material from becoming lodged between the end of the drum and the conditioner section housing. A support bar is added to proved structural support to the teeth and to provide a tooth at the end of the support bar point toward the housing wall to further prevent materials from becoming lodged between the end of the drum and the conditioner section housing. The rotation teeth pass between stationary fingers. The finger may further include finger teeth. The length of the fingers, the distance between the finger and the drum, and the finger teeth configuration may be remotely selected to provide for conditioned materials of different sizes.Type: ApplicationFiled: November 1, 2008Publication date: May 7, 2009Inventor: Ronald Dean Carpenter

Publication number: 20090108110Abstract: The present invention regulates the delivery of feedstock to the fragmentation zone in a gravity-fed comminuting machine and reduces the ejection of feed materials by means of a rotating cylinder located at an offset position above the rotor. Rotationally mounted on an axis parallel to and above, but offset from, the axis of the rotor, this cylinder serves primarily as a striking surface, or anvil. The continual rotation of the anvil, in the opposite rotational direction as the rotor and with much slower rotational speed, assists in agitating the feed material, alleviating the problems of feed chute obstructions and feed aggregation. The cylinder forces the feed materials into contact with the rotor teeth through continuous rotation and provides a novel tooth design to improve efficacy and reduce wear.Type: ApplicationFiled: October 24, 2008Publication date: April 30, 2009Inventors: Jamey O. Brick, Douglas G. Meyer, Nick D. Lieser, Dennis D. Finken, Todd J. Marquardsen

Patent number: 7506830Abstract: In a toner production process having at least a kneading step, a pulverization step and the step of simultaneously carrying out a surface modification step and a classification step to obtain toner particles, the surface modification and the classification are simultaneously carried out using a batch-wise surface modifying apparatus having at least a cylindrical main-body casing, a classifying rotor, a surface modifying means having a dispersing rotor and a liner. The positional relationship between the dispersing rotor and the liner is set in an appropriate specific state so that toner particles having a narrow particle size distribution with less fine powder and having a high sphericity can be obtained with a good efficiency.Type: GrantFiled: February 22, 2008Date of Patent: March 24, 2009Assignee: Canon Kabushiki KaishaInventors: Takeshi Naka, Osamu Tamura
