Parallel Material Flow Through Plural Comminuting Zones Patents (Class 241/134)
  • Patent number: 7762484
    Abstract: A machine is provided for distributing blowing wool from a source of compressed blowing wool. The machine is configured to discharge the blowing wool into distribution hoses. The machine including a shredding chamber having an outlet end. The shredding chamber includes a plurality of shredders configured to condition the blowing wool. A discharge mechanism is mounted at the outlet end of the shredding chamber. The discharge mechanism is configured for distributing the conditioned blowing wool from a discharge mechanism outlet end into an airstream provided by a blower. A choke is positioned between the outlet end of the shredding chamber and the discharge mechanism. The choke is configured to direct heavier clumps of blowing wool to the shredding chamber for further conditioning and configured to allow conditioned blowing wool to enter the discharge mechanism.

  • Publication number: 20090194620
    Abstract: The present invention provides an impact crushing apparatus that includes a housing, a chamber defined within the housing, a rotor assembly for receiving material and throwing the material radially outward, a lid for closing the chamber, and a plurality of anvils positioned around the rotor assembly and configured to break apart the material. The lid includes a plurality of openings positioned about its perimeter and the plurality of anvils are slidably receivable in the plurality of openings, wherein the anvils include a top portion and a bottom portion having an impact surface configured to break apart the material, the top portion being supported by the top surface of the lid and the bottom portion positioned within the chamber such that the material collides with the impact surface of the plurality of anvils and breaks apart.

  • Patent number: 6832737
    Abstract: The method and assembly accommodate parallel processing of a plurality of materials such as catalysts simultaneously through use of interactive modules for sizing of material particles to predetermined substantially identical size, for collecting a substantially identical dose of each material, for feeding the dose of each material into a reactor vessel, and for maintaining integrity of the modules, or units thereof, intact during interaction between structures so no particulate material is lost during necessary processing for ultimate efficacy testing in a least compromised manner.

  • Publication number: 20020014546
    Abstract: Methods and apparatus for combinatorial (i.e., high-throughput) materials research, such as catalysis research, that involves parallel apparatus for simultaneously effecting mechanical treatments such as grinding, mixing, pressing, crushing, sieving, and/or fractionating of such materials are disclosed. The methods and apparatus are useful for mechanically treating catalysis materials and other solid materials, including without limitation, electronic materials such as phosphors, colorants such as pigments, and pharmaceuticals such as crystalline drugs or drug candidates. The simultaneous protocols and parallel apparatus offer substantial improvements in overall throughput for preparing arrays of materials, such as catalysis materials.

  • Patent number: 4718611
    Abstract: The invention relates to a device for the production of mechanical pulp from a lignocellulose material, comprising a grinding disc (1) rotating round a shaft (2) running at right-angles through the center of each end surface of the disc, and means (10-13) for holding and pressing one or more pieces of the material to be processed against one or both of these end surfaces, which are given the form of grinding surfaces, for fibres of the material to be processed being essentially oriented in the plane of the grinding surface, and water, which may contain chemicals, being introduced during the grinding process. The grinding disc is enclosed in a housing (5) kept at above-atmospheric pressure. The means for holding the material to be processed is so designed as to hold the pieces of such material with their fibres largely pointing in a direction outwards from the center of the grinding device.
