  • Patent number: 10307764
    Abstract: The present invention relates to a machine frame for a roll crusher that has two side walls and two end walls, where the mentioned end walls accommodate the storage of the rolls. The end walls are split horizontally in the area of the mounting of the rollers, and vertically between the mountings of the upper part. One advantage is that to remove a roller, removal of the respective upper end wall is sufficient. In a preferred embodiment of the invention, the adjacent upper parts of the end walls do not touch. An advantage of this is that tilting of the end wall upper parts among each other or in contact with the side walls is prevented during removal. Furthermore, the gap resulting from the distance between the front wall upper parts in the preferred embodiment would be sealed, with the advantage that no material and dust can exit.

    Abstract: The present invention discloses an apparatus for trimming plants, in particular, buds and flowers, to remove unwanted plant material. A typical application would be to process a plant to leave only trimmed buds and flowers for use in potpourri, fragrant sashes, or as a prelude to further processing of essential oils. The invention enables faster and safer production of plant material than prior plant processing machines. The apparatus employs an original combination of a slotted metal drum and a lawn mower type cutting reel that are rotated in the same direction, but at different speeds, to create a cutting interface that shears the unwanted plant material off and then collect this debris though a novel vacuum manifold into a waste collection device. The cutting interface between the slotted drum and the cutting reel is adjustable to keep the distance between the two between 0.002 and 0.006 inches for a very sharp and clean cut.

  • Patent number: 5694709
    Abstract: A pipeline padding machine is provided comprising a crushing mechanism for crushing large pieces of excavated material into smaller pieces of material that are suitable for use in padding a pipeline or underground cable. In preferred embodiments, the crusher comprises two parallel rollers that are arranged with a selected gap between them. The rollers are driven toward each other, such that excavated material that is fed onto the rollers is drawn into the gap, and pieces that are too large to fall through the gap are crushed by the rollers. The crusher mechanism may be installed on a known type of padding machine, preferably at the end of the transverse conveyor over the trench. Alternatively, the crusher may be mounted on the padding machine frame. The output material from the crusher may be screened or otherwise processed, or it may be delivered directly to the trench.

  • Patent number: 5678777
    Abstract: At least a pair of metal rolls having different peripheral speeds with each other are removably mounted to respective rotary shafts in a cantilever form. The axial length of each of the metal rolls is between 100 and 500 mm and the peripheral speed of the high speed roll is between 12 and 30 meter/second. A cover is fitted to a milling chamber that houses therein the paired metal rolls and has a transparent member at least as a part thereof. With such an arrangement, the rolls can be replaced with ease and the milling operation carried out in the milling chamber can be easily monitored through the transparent member.

  • Patent number: 5601242
    Abstract: A roller press (1; 11) for grinding of granular material and comprising two or more rollers (3, 5; 13, 14, 15) alternately rotating in opposite directions, of which at least one is displaceable in a guideway (7; 16, 17) and where only some of the rollers (5; 14) are connected to a driving means. According to the invention the guideway for each of the displaceable rollers is provided so that it is substantially parallel to the resultant force on that roller. As a result, virtually all of the resultant force acting on the displaceable roller will be acting substantially eliminating the reaction force at right angles to the guideway.

  • Patent number: 5553796
    Abstract: A roller mill having a fixed roller and a floating roller mounted on a frame and driven in opposite directions includes two gear units for the rollers and two independent torque absorbers to minimize the transfer of torque loads to the frame. Each torque absorber has a pair of two arm levers pivoted at spaced axes on the frame so that one end of each lever is adjacent one end of the other. A first force transmitting member couples the adjacent ends of the levers to each other and a second force transmitting member couples the opposite ends of the levers to the associated gear unit.

  • Patent number: 5381977
    Abstract: The invention relates to apparatus for material bed comminution of brittle material for grinding, with two roll-like comminuting tools, in which the length:diameter ratio is in each case less than 1 and of which one tool is fixed and the other is mounted so as to be movable, wherein a working gap distance is maintained between the two comminuting tools in the unloaded starting position and the comminuted material for grinding is substantially pressed to form agglomerated scabs. In order to ensure a relatively low wear and a relatively maintenance-free operation the length:diameter ratio of the comminuting tools is less than approximately 0.3 and the diameter of the roll-like comminuting tools is chosen to be sufficiently great that the scab thickness is always greater than the working gap distance.

  • Patent number: 5362001
    Abstract: Rubber scrap is pulverized by feeding it into a gap between a parti-cylindrical recess in a block and a cylinder rotating in the recess. A plurality of blocks are mounted one above another in a first frame, and a like plurality of cylinders are mounted in a second frame. The blocks are so arranged that rubber scrap pulverized in the recess of one block is fed into the recess of the next lower block for further pulverizing. All of the cylinders are driven in rotation by a single motor through a belt or chain drive. A hydraulic cylinder piston unit is provided for raising the first frame relative to the second frame and thereby varying the gaps between the cylinders and the respective recesses of the blocks.

  • Patent number: 5154364
    Abstract: A grinding clearance adjustment device for milling roller frames is disclosed, in which a casing contains two grinding rollers, one of which is constructed as a pivotable loose roller. Adjustment members, for the rollers are provided, as well as a device for the automatic setting of the grinding clearance by means of a remotely controllable drive motor, the latter being coupled to the adjustment members via transmission means. The motor operates through a clutch. In the preferred embodiment, the adjustment members are constructed as a first closed standard component, which has a lever-transmitted setting part with a longer and a shorter lever arm and which is laterally positioned in the vicinity of the grinding rollers. The drive motor and clutch are constructed as a second closed standard component, which is spaced from the first standard component, and the adjustment forces derived from the drive motor are coupled to the longer lever arm of setting part.

  • Patent number: 4982907
    Abstract: A document shredder comprises a pair of cutter assemblies, each having a shaft on which there are cutter disks with interspersed spacers. The disks overlap to form a nip. On the one shaft, additionally, there are rings mounted in the spacers, and that permits the shaft to be axially compressed tighter than the shaft without rings. This provides for relative flexibility and axial movement between the shafts such that foreign objects can more easily be removed. A 20 inch cutter assembly driven by a single phase motor through a planetary gear system is provided.
