Abstract:
An apparatus for cutting cuttable pieces, especially of animal or vegetal origin, into prismatic, preferably cubical shape, includes two concentric knife rotors, inner and outer knife rotors. The inner knife rotor carries a first cutting tool for cutting the cuttable pieces into slices and strips. The first cutting tool includes a plurality of plate-shaped knives and a plurality of sets of gate forming knives positioned in passage channels formed in the inner knife rotor. Each set of gate forming knives is positioned adjacent to and upstream of one of the plate-shaped knives. The gate forming knives first simultaneously cut the cuttable pieces into a plurality of strip sections. The associated plate-shaped knife then slices the strip sections to form individual strips, which are led out of the passage channel. The outer knife rotor carries a second tool, a plurality of plate-shaped knives, that cross cuts the strips coming out of the passage channels according to the desired length. Guides, which press the cuttable pieces against the first cutting tool, are arranged in the interior of the inner knife rotor. The guides can have either a spiral-shaped guideway fastened onto a housing door or rotating guiding vanes.

Abstract:
A device for the determination of the state of wear of comminuting tools a comminuting tool, a comminuting device with such a comminuting tool, and a corresponding method. A reference surface is provided on the comminuting tool, the surface from which the distance A0, A1 to the active edges of the comminuting tool can be determined. The degree of wear then results from a comparison of the original distance A0 in an unused comminuting tool with the distance A1 reduced due to wear after a certain period of use. The thereby achieved advantage is that the state of wear can be determined independent of the general wear of the comminuting device. A distortion of the measurement result caused by this is therefore ruled out.

The rotor includes a drive shaft on which a predetermined number of rotor discs are provided and over the circumference of which grinding tools are arranged. In accordance with an embodiment, it is provided that frictional connection elements are arranged between the rotor discs forming axial ends of the rotor and the shaft for transferring a torque, and that power transmission elements are arranged in a contact surface of two adjacent rotor discs and that the rotor discs can be clamped together with axially acting clamping elements.
Abstract:
An apparatus for chipping material, particularly wood, includes a plurality of knife carriers are arranged around a mutual axis that form the boundaries of a cutting chamber while forming a comminution path. On the knife carriers, the slicing knives, under inclusion of a cutting angle δ, are detachably attached to the comminution path. The blades of the slicing knives uniformly project into the cutting chamber. To adjust the cutting angle δ so as to adapt it to the prevailing conditions, a control element for determining the cutting angle δ is detachably arranged between the slicing knives and the knife carriers.
Abstract:
An apparatus for comminuting material is provided. The apparatus includes two disks, which are arranged coaxially to one another inside a housing that encloses a comminuting room. The rim areas of the disks are positioned opposite one another, thus forming a milling gap, and are provided with interacting comminuting tools. To generate a mutual relative movement of the disks, at least one of the disks carries out a rotational motion around the mutual axis. To comminute the material, it is first fed into the comminuting room and subsequently radially channeled to the milling gap. For additional cooling, the disk on the intake side is arranged at an axial distance to the intake side of the housing front wall, thus forming a ringwheel-shaped cool air conduit. This can be charged with cool air, which flows through the conduit in a radial direction. In this way, the machine capacity can be increased without causing thermal damage to the material to be processed.
Abstract:
An apparatus for comminuting materials includes a rotating or stationary ring of knives that is arranged around a chipping chamber. The ring of knives is has a plurality of knife carriers, which are distributed around the knife ring axis in a circular shape, each knife carrier having a bearing surface. The bearing surface is a receptacle for a knife package that is comprised of a knife retaining plate and a slicing knife, and which is held in an operational position at a predetermined angle and a predetermined blade projection by fasteners. The knife carrier has a reference surface, which interacts with the knife package, and based on which the blade projection is determined. The slicing knife has at least one recess that originates in a rearward longitudinal edge, whereby the reference surface is arranged on the projection inside the recess, the projection extending vertically to the bearing surface.
Abstract:
An apparatus for comminuting material includes two disks arranged coaxially to one another inside a housing that encloses a comminuting room. At least part of the opposing surfaces of the disks are provided with interacting comminuting tools thus forming a comminuting zone, whereby at least one of the disks rotates around a mutual axis to generate a relative movement of the disks. At the same time, the material, which is a mixture of gaseous and solid materials is axially fed by one of the disks into the comminuting room and is radially conveyed to the comminuting zone. Thereby, cooling gas is additionally channeled into the comminuting room. The comminuting room is partitioned into one chamber through which the mixture of gaseous and solid materials flows, and at least one additional chamber dedicated to the cooling gas.
Abstract:
An apparatus is disclosed for converting feed material into granules under the application of pressure. The apparatus includes a conveyor screw arranged about an axis of rotation with at least one screw spiral, a rotationally symmetric working chamber arranged about the axis of rotation, which chamber is formed by two annular walls arranged at an axial distance from one another and by an annular perforated die. The annular wall has a central opening arranged coaxial to the axis of rotation into which the conveyor screw discharges in order to feed the working chamber with feed material. The apparatus also includes a pressure element that rotates about the axis of rotation and has at least one pressure arm, which extends from the axis of rotation toward the perforated die delivers the axially supplied feed material to the perforated die in the radial direction, and compacts it while doing so.
