  • Patent number: 7559493
    Abstract: A media basket mill utilizes a media bed having very small media to attain a mixture of finely divided solids in a liquid vehicle. A bearing construct which journals the rotor of the basket mill within the basket of the mill includes a bearing which is protected against excessive wear by including a recess in the rotor. The recess is juxtaposed with the bearing and communicates with the media bed such that upon rotation of the rotor to pass feedstock through the media bed for a mixing operation, media and feedstock in the vicinity of the bearing will be directed from the recess into the bed of media and feedstock outside the rotor, thereby diverting media and feedstock away from the bearing and deterring excessive wear which might otherwise result from media and feedstock interacting with the bearing during rotation of the rotor for the mixing operation.

  • Patent number: 7533837
    Abstract: A comminuting device includes a comminuting chamber which has a bottom wall and a circumferential wall which extends upwards from the bottom wall. The device also includes a rotatably driven drive shaft which extends essentially orthogonal to the bottom wall, and at least one comminuting element which is disposed next to the bottom wall. This at least one comminuting element can be made to perform a rotary movement about the drive shaft by the drive shaft. A plurality of additional comminuting elements which can be made to perform a rotary or revolving movement about the drive shaft (22) by means of the drive shaft are arranged above the at least one comminuting element comminuting element disposed next to the bottom wall.

  • Patent number: 7389954
    Abstract: A food grinding machine comprises a static outer jacket provided with conventional elements for coupling to a loading inlet of the grinding machine. Annular recesses are formed in the internal thickness of the jacket, have preset volumes and are mutually separated. A food pusher and cutter element is mounted inside the jacket so that it rotates coaxially, and a screening element with differentiated passage regions is interpose between the pusher and the jacket. Each region can be crossed at the annular recesses.

  • Patent number: 7318880
    Abstract: The invention relates to a method for defibering recycled fiber material in a drum pulper provided with a substantially horizontal drum. Recycled fiber material and water are fed to the drum pulper and the drum of the drum pulper is simultaneously rotated. When the drum rotates, the recycled fiber material rises up in the rotating drum and finally, due to gravitational force, falls back down. After falling and hitting to the bottom, the recycled fiber material is defibered, forming a fiber pulp mixture with water. A value of at least one parameter describing the defibration process or fiber pulp properties is measured on the basis of the drum pulper or the resultant fiber pulp mixture, and this value is used for controlling the rotation speed of the drum of the drum pulper. The invention also relates to a drum pulper implementing the method of the invention.

  • Patent number: 7306176
    Abstract: Devices, assemblies, and compression members for regulating the pressure or dwell time within separating machines that separate hard material from soft material are disclosed. The device utilizes a compression assembly comprising a compression member, a base member, a primary key, a primary key receptor, a secondary key, and a secondary key receptor for controlling the amount of material that is forced through a conduit. The primary key, the primary key receptor, the secondary key, and the secondary key receptor secure the compression member to the base member. The devices, assemblies, and compression members of the present invention regulate the pressure exerted on the separating machine by the compressed hard and soft materials and also regulate the dwell time of the hard and soft materials within the separating machine in a manner that reduces the difficulty, expense, and associated time of replacing worn compression members.

  • Patent number: 7284716
    Abstract: Disclosed is an agitating device (3) to be disposed in a batch-type vessel or the like. The agitating device (3) has an upper cover plate (5), a bottom cover plate (6), an impeller (7), an inner screen member (8), and first and second outer screen members (9, 10). When a mixed liquid including a dispersoid and a dispersion medium passes through liquid communication holes (19) of the inner screen member (8) and liquid communication holes (22, 25) of the outer screen members (9, 10) during the course where it flows outward from the impeller (7) to get out of an interplate space, the circumferential component of the flow vector of the mixed liquid is mostly eliminated to allow the mixed liquid to have substantially only the radial component. This prevents the generation of vortexes so as to apply a sufficiently high shearing force to the mixed liquid to effectively prevent the formation of macro bubbles in the mixed liquid.

  • Patent number: 7252036
    Abstract: A rotor for food pulping or straining machines is equipped with a plurality of blades (2) designed to act on the food product to force at least part of it out through a sieve (3) that surrounds the rotor (1) and is characterised in that the blades (2) are shaped in such a way as to cause sudden changes of direction in the moving product particles, thus producing a rapid succession of impulses that act on substantially stationary product particles adhering to the sieve (3), these impulses causing the propulsion of the substantially stationary product particles.
