    Abstract: A feed device for a high-pressure roller press for the high-pressure comminution of material to be ground, the feed device feeding the material to be ground in a controlled manner into the roller nip between two rollers of the high-pressure roller press. The feed device has at least two rotary valves, the position of which is variable independently of each other. In a refinement of the invention, the feed device also has a shaft which is variable in height above the roller nip. By means of the rotary valves which are variable independently of each other and by means of the height-variable shaft, the feeding behavior of the feed device can be varied during the starting of the high-pressure roller press and during the operation of the high-pressure roller press in order thereby to prevent the high-pressure roller press from vibrating and to ensure optimum operation of the high-pressure roller press.

    Abstract: A single-motor shredder has a housing, and multiple cutting rollers, a paper feeding mechanism and a motor mounted in the housing. A first gear set connects the cutting rollers with the motor and a second gear set connects the cutting rollers with the paper feeding mechanism. Only one motor is needed to drive the cutting rollers and the paper feeding mechanism. Therefore, the shredder is light and a manufacturing costs of the shredder are lowered. Moreover, the paper feeding mechanism separates a stack of paper into small piles to sequentially feed the stack of paper in small piles. Thus, the stack of paper does not jam the cutting rollersso improving lifetime of the shredder.

In order to hold the chute in an operative, i.e. upright position, the device is provided with a support member that is pivotally connected to the rear side of the chute. For holding the chute in the upright position, the free end of the support member bears against a stopper provided on the flange.

  • Patent number: 7021576
    Abstract: The invention describes a blade mill for grinding plastic material with a rotor which is driven in rotation inside a grinding chamber and has a plurality of radially outwards-pointing cutter blades distributed around its circumference and a plurality of stationary, radially inwards-pointing stator blades projecting into the grinding chamber and forming a blade gap with the cutter blades, wherein cutting spaces widening radially outwards in a crescent shape and located radially outside the turning circle of the rotating cutter blades are located ahead of the stator blades in the direction of rotation of the rotor. To prevent the plastic material which is to be ground from backing up in the cutting spaces and from being crushed against the wall of the screen baskets, the invention provides that the motion path of the rotor blades extend eccentrically with respect to the axis defined by the screen baskets.

  • Patent number: 6978956
    Abstract: A granulator has a first coarse cutting stage operating at between 5 and 45 rotations per minute and a second fine cutting stage operating at two to ten times the speed of the first stage. Since granulate exiting the second stage is uniformly divided, the granulator operates independent of a screen. A first cutter stage has cutting segments having blades interspersed with deflector segments about a shaft. Rotation of the shaft urges the blades past a spaced stationary cutter.

  • Patent number: 6454196
    Abstract: A shredder (2) for shredding a variety of different materials includes a fixed framework provided with a cutting assembly (20) having at least two counter-rotating cutting arrays (22, 24) each comprising a plurality of cutters (46) and a movable framework provided with a tensioning arrangement (100) for applying the same tension to each of the cutting arrays (22, 24) to shred material fed to the cutting arrays (22, 24) by a telescopically sided chute (10) having a tapering mouth (14) and a throat (16). The movable framework is movable with respect to the fixed framework in accordance with operation of an adjustment means (102) to alter the tension applied to the cutting arrays (22, 24) in order to apply constant tension to the cutting elements (46) to compensate for wear of the cutting elements (46) during use of the shredder.

  • Patent number: 6390397
    Abstract: An automatic paper shredder is capable of sequentially cutting up to 20 sheets of 20-lb bond paper, up to 9 inches wide. The device has adjustable holders for attachment to conventional wastebaskets of varying shapes. A feed tray holds the stack of paper. Upon selection of either manual (ON) or automatic (AUTO) operation of the machine, a single sheet of paper is fed into the machine by a roller as are subsequent sheets, if any. With the three-way switch set to AUTO, any sheets on the tray are detected by a sensor and are automatically fed into the machine for shredding. A plug-in motor contained in the housing of the machine drives a plurality of shafts for the feed roller and knife rollers. The knife rollers are configured to either shred the paper into about ⅜-inch wide strips or to cross-cut the paper into a plurality of smaller pieces.

  • Patent number: 6032884
    Abstract: In an otherwise conventional star feeder, equipment longevity is greatly enhanced by providing a readily replaceable shear edge at the downstreammost (in the direction of rotor rotation) portion of the feeder housing inlet, adjacent the clearance between the rotating pocketed rotor and the housing. Preferably one or more plates defining the shear edge are mounted by fasteners, such as screw threaded fasteners, to the housing. Where the feeder is retrofit, with the replaceable shear edge, a recess may be formed in the housing to accept and position the one or more shear plates. A shear plate may have a number of openings elongated in a dimension intersecting the clearance adjacent the inlet, and by loosening or tightening fasteners the position of the plate shear edge may be adjusted with respect to the clearance to provide an effectively new shear edge when it becomes worn. At least the shear edge portion of the shear plate may be of a hard wear resistant material, e.g.

  • Patent number: 5845857
    Abstract: A coffee mill providing for mixing of coffee beans in different ratios includes a bin partitioned in the middle to form two chambers holding two different types of coffee beans. An outlet in the bottom center of the bin leads to a coffee grinder. This central outlet is surrounded by a base cylinder having a side opening leading to each chamber of the bin. The cylinder is covered by a cylindrical closure cap, also partially open on the side. The cap can block both chambers of the bin, one chamber, or provide partial blocking to one side and none to the other, thus allowing the user to adjust the ratio of different coffee beans by rotating the cap. The bin interlocks with the housing of the grinder, but can be disengaged for removal. The cylindrical closure cap is positioned to block the outlet from both section of the bin when the bin is to be removed.
