  • Patent number: 7070135
    Abstract: A chipping apparatus includes a housing arranged about an axis of rotation and a chipping system within the housing rotating in a predefined direction about an axis of rotation. The chipping system has chipping tools that form a circular or ring-shaped chipping zone. The housing is divided into the sectors I, II, III and IV in the direction of rotation, with a material outlet being arranged in sector I. The axis of rotation of the chipping system is arranged eccentrically, with respect to a central axis of the housing, in the region of sector I or II. In this way, a uniformly widening flow channel is produced between the chipping tools and the housing, even when the housing is circular in cross-section. The constant volume increase in the flow channel toward the material outlet prevents an increasing material density, which can cause blockages in the material flow.

A feeding device which rotates with the rotary knife or knives extends into the funnel-shaped section and has one or more arms whose edge portions resemble spirals or helices having a lead opposite to that of the spiral surface.

  • Patent number: 4140282
    Abstract: A comminuter for metal turnings and the like has a rotor rotatable on a support about a fixed axis and carrying at least one outer rotor element and at least one inner rotor element which define a cylindrical orbit on rotation of the rotor. A housing surrounds this rotor and is formed by a U-shaped upwardly open portion of non-tapering cross-sectional shape and a flat cover part engageable over the open upper side and openable in order to clear a jam in the machine. Stator elements carried on this housing are spaced slightly from the rotor element so that as the rotor turns turnings and the like fed to the machine will be comminuted and passed from an inlet to an outlet end.

  • Patent number: 4109873
    Abstract: A grinding mill having a feeding chamber for directing grain between grinding stones where it is ground into flour and from where it is discharged into a turbine chamber. Means are provided for directing cooling air into the turbine chamber, across the rotating grinding stone, and centrifugally out of the housing through a tangential discharge nozzle. The relative position of the grinding stones is easily varied by using a control handle to move the drive shaft of the motor, on which the rotating grinding stone is mounted. The position of the control handle is fixed by wedging it to a portion of the mill housing.

  • Patent number: 4082234
    Abstract: A matched pair of coaxial milling wheels for small flour mills such as those used in homes. A stationary milling wheel and an adjacent rotatable milling wheel each have a common central axis. Each includes first and second radial surfaces spaced along the axis. The adjacent faces of the wheels have a center cavity extending axially inward and defining the inner periphery of an annular milling face extending to the wheel periphery. Complementary grooves are formed in the milling face of both wheels to feed grain radially outward from the central cavities and to assist in cracking and grinding the particles to a fine state. The wheels are formed integrally from fired stoneware and have machined flat annular rims about the milling faces to assure accurate final grinding of the particles before they exit from the space between the two wheels.

  • Patent number: 4057194
    Abstract: A portable flour mill includes a fixed grinding wheel and a rotatable grinding wheel located inside a box-like housing. The fixed grinding wheel has a smooth and a tapered portion on its grinding face and is fastened to a removable interior wall of the housing. The rotatable grinding wheel has five symmetrically arranged V-shaped radial grooves on its grinding face and is journaled for rotation in a fixed interior wall opposite the fixed grinding wheel. The fixed grinding wheel is provided with an entranceway for receiving the grain which is to be ground. A feed hopper rests on a plate fixed to the removable interior wall and includes an exitway coincident with the entranceway of the fixed wheel. The wheels are selectively spaced apart with each other to grind different types of grain. Means for adjusting the spacing between the two wheels are disclosed.

  • Patent number: 4039153
    Abstract: A mill for grinding flour and the like. Two flat grinding discs are mounted in opposed relation to one another. One disc is non-rotatably mounted with respect to the housing that supports it, while the other is rotated by a motor drive. The non-rotatable disc coaxially supports the shaft for the rotatable disc. The non-rotatable disc can be adjusted axially to vary the spacing between the grinding surfaces of the respective discs. Provision is also made for yieldable movement between the discs in response to the grinding load.

  • Patent number: 4037797
    Abstract: A grinding mill arranged in a housing having a stone grinding wheel turned by a power source such that a face thereof moves over a fixed grinding stone. Grain deposited between faces thereof is ground into meal or flour and falls into a receptacle preferably in the housing that can be removed therefrom. The invention provides a feed arrangement for passing whole grain from a trough, through an opening in the fixed grinding stone to a location between the faces.Adjustment of spacing between the faces of the stone grinding wheel and fixed grinding stone is provided by the inclusion of a manually turnable shaft arrangement that attaches to a threaded sleeve fixed to the electric motor. The turning of the shaft draws the electric motor toward or urges it away from a fixed point to shift the electric motor within the housing, so as to vary, as desired, the spacing between the faces.

  • Patent number: 4033516
    Abstract: The movement of material being ground and/or to be ground within a grinding apparatus having opposed grinding wheels can be employed in order to promote the flow of the material to generally between the grinding wheels. A grinding apparatus to utilize such movement for this purpose has in addition to the grinding wheels a structure for causing relative rotation between the wheels, an inlet opening leading through the center of one of the wheels to generally between the wheels, and a hopper for conveying material through this opening to generally between the wheels. In addition, such an apparatus includes a shaft rotatably mounted on a bearing between the hopper and a finger or agitator extending from the shaft generally toward and preferably to within the opening in the grinding wheel, at least a portion of this finger or agitator being spaced from the axis of the shaft.

  • Patent number: 4015784
    Abstract: Apparatus for emulsifying sausage batter and the like wherein sausage batter to be emulsified is first gravity fed from a hopper into the inlet of a comminuting chamber. The batter is then impelled radially outwardly into a rotating centrifugal trap which is adapted to centrifugally remove impurities such as metal particles and to direct the material downwardly through a series of alternately rotatable and non-rotatable perforate rings. The interaction of the rings comminutes and emulsifies the batter as it passes therethrough, whereupon it exits vertically from the lowermost of a series of rings and is swept by rotating blades into a tangentially disposed discharge conduit.

  • Patent number: 3984057
    Abstract: A disc refiner for pulp has a housing defining a chamber with an inlet and an outlet, three coaxial discs mounted in the chamber, and a shaft which rotates the central disc and extends with clearance through a large opening in one of the outer discs. The other outer disc is adjustable axially toward and away from the central disc and the central disc is movable axially of the shaft between the two outer discs. The stock enters via inlet and passes through the opening of the one outer disc. A portion of stock thereupon passes radially outwardly between the one outer disc and the central disc to be comminuted by ribs on the adjacent surfaces of the one outer disc and the central disc. The remaining portion of stock flows through several relatively large openings of the central disc and thereupon radially outwardly toward the outlet by passing between ribs provided on the neighboring surfaces of the central disc and the other outer disc. Each of the discs is a one-piece body.
