  • Patent number: 5823452
    Abstract: A flaker mill provides for the flaking or rolling of processed grains such as corn and milo for livestock feed. The mill is powered by a relatively small motor which turns at a higher speed than the drive sheaves for the two rollers within the machine. A speed reduction transmission, such as a planetary transmission, is used to reduce the motor output speed to the proper speed to drive an output sheave from the transmission and to provide the proper torque for the two rollers. Each of the rollers has a sheave extending therefrom, for a total of only three sheaves for the entire machine to drive the two rollers. The machine does not require an idler pulley or sheave for belt tension adjustment, as the arcuate adjustment motion of the rear roller bearing housings disposed between the fixed front roller bearing housings and the transmission output, substantially compensates for positional changes in the belt run.

    Abstract: This invention pertains to the cutter area of size reduction equipment for plastic or other waste material. The primary objective of this invention is to provide a feed mechanism and secondary cutting section to an existing shredder technology. Inasmuch as a properly designed shredder mechanism will produce a uniform material width, a feed mechanism was developed to maintain the orientation of the shreds as they exit from the shredder, and to meter them into a secondary cutter system at a predetermined rate of speed. Said secondary cutter system is so designed that the subsequent cutting action is at a plane perpendicular to the first cutting action. By maintaining said orientation of the shreds, and by controlling the rate of in-feed to the secondary cutter, a uniform chip is produced with a predetermined width and length dimension.

    Abstract: The apparatus for feeding rolling mills, particularly for oil seed, comprises two rotatable feed rollers located in a feed mechanism housing above the rolling mill. The feed rollers are substantially vertically oriented and are rotatable in opposite directions. The housing wall running in the longitudinal direction of the feed rollers engages closely on an upwardly moving circumferential portion of the lower feed roller, in order to ensure that no material passes through in this area. All the material to be ground passes through the gap. Since the gap is formed by two feed rollers, whose surfaces move in the direction of the material, no lumps and the like collect upstream of the gap and consequently cause a non-uniform material flow. The apparatus permits a very uniform flow and simultaneously breaks up lumps.

Each feeding shaft includes three radially extending, evenly spaced paddles fixedly mounted thereon. The feeding shafts rotate at the same speed and are rotationally aligned to cause each paddle on one feeding shaft to generally lie within a common plane with a corresponding paddle on the other feeding shaft as they pass closely by one another. Each of the paddles has a plurality of gripping teeth on the extended end thereof.

  • Patent number: 4697748
    Abstract: The invention relates to a method for macerating and wet-crushing brewing ingredients, wherein the brewing ingredients are continuously taken from a supply container. Subsequently substantially equal portions of the brewing ingredients are conveyed along a circular path, and an excess of macerating water is added thereto. The excessive macerating water is collected and discarded, whereupon the brewing ingredients are fed to a wet-crushing mill. A simplification of known methods, and of the structure of known apparatus for carrying out such method is achieved by the provision that the macerating process is carried out exclusively during transport of the brewing ingredients along the circular path, and that the macerated brewing ingredients are then immediately fed to the wet-crushing mill.

  • Patent number: 4564146
    Abstract: A paper-shredding machine has a sleeve mounted for limited movement towards and away from a surface of a housing of the machine to define an inlet opening, through which paper can be fed to cutters disposed within the housing. The sleeve normally occupies a position in which the inlet opening is closed but can move relative to the housing to admit paper through the inlet opening.

  • Patent number: 4513918
    Abstract: An apparatus for uniformly dispensing particulate food materials onto a moving article which comprises a hopper for holding a supply of the particulate and having a horizontally disposed orifice through which the particulate material can exit, a rotatable drum located below the orifice and having a plurality of spaced fins protruding radially therefrom and disposed on a zig-zag pattern and operable to counteract the tendency of the particulate material to fall off the drum, and a scraper adapted to engage the drum surface between the fins and operable to follow the zig-zag pattern of the fins to lift particulate material off the surface of the drum and guide it to a discharge precipice over which it falls onto the moving article.

  • Patent number: 4422581
    Abstract: One aspect of the invention is a tire debeading machine (10). A tire is supported on a guide apparatus (15) and raised to an operative position by the action of a support arm (21). A cutting blade (33) is moved against the sidewall of the tire, cutting off the bead. After the initial cut is made, the tire is raised slightly further by the combined action of an initially interlocking vertical arm (75), which extends from said support arm (21), and a roller (71) on an L-shaped arm (69). The further cut by blade (33) is closer to the bead. Another aspect of the invention is a granulating machine which includes three feed rollers (93) (95) (97) which feed the debeaded tires into a cylindrical cutting chamber (106). Inside the cutting chamber (106) are a plurality of rotary cutting blades (127) mounted on mounting plates (130), which cooperate with stationary cutting blades to produce granulated rubber particles and fiber particles.
