  • Patent number: 8727253
    Abstract: A three roll mill having a feed roll, a center roll, and an apron roll with that are driven so that their cylindrical surfaces move in the same direction but different speeds in each nip. One end of each roll is engaged by a drive shaft at a first side of the mill, whereas the other end of each roll rotates freely at a second side of the mill. Each roll can be removed individually and without tools by moving the roll away from the first side against a spring force in the second side. This disengages the roll from its drive shaft, whereupon it can be lifted out of the mill.

  • Publication number: 20090008485
    Abstract: Crushing finely the chipped rubber such as that of waste tire is done by further small number of crushers, and the capture rate of the target size of the rubber particles is improved. With a crusher which finely crushes the chipped rubber (G) such as that of waste tire, the chipped rubber (G) is supplied to a crusher (10a) structured by a rotating roll (12) having relatively rough groove pitch and pluralities of fixed blades (14) each of which has pluralities of grooves forming crushing edges, thus conducting crushing. The rubber particles (G) discharged from the crusher (10a) are again supplied to the crusher (10a) to repeat the crushing to conduct rough-finishing operation. Then, thus roughly-finished rubber particles (G) are treated by similar crushing operation using a rotating roll (10b) having relatively small groove pitch to conduct finish treatment. The finely-crushed rubber particles are classified using a sieve (16) to specified size ranges.

  • Patent number: 5904305
    Abstract: A rubber reduction and recycling system with dramatically reduced power requirements. The present invention provides a series of reduction stations which successively reduce the size of the rubber, typically in the form of tires, to eventually result in crumb rubber. The power requirements are dramatically reduced by providing a fixed cutting plate through which the teeth of the cutting apparatus pass and cut the rubber in a shearing fashion. Moreover, the teeth of the cutting apparatus pass through the fixed cutting plate at an angular disposition so that at any given point, a relatively small portion of the rubber is being cut and thereby consuming power. Finally, the power consumption is reduced by providing the teeth on rotating shafts in a plurality of series of arcuate patterns. Therefore, at any given time, only a relatively small number of teeth in each series cut at the same time and thereby require power.

  • Patent number: 4998675
    Abstract: The solid waste processing unit will reduce normal waste stream solids, all considered to be nonedible garbage, to 10-15 percent of the original volume ready for recycling or disposal. The unit can be placed in any location and can be manufactured to meet any capacity. The unit crushes, tears and shreds solid waste in a disintegrator which is composed of two sections. The first is a stationary chamber and the second is top cone-shaped drum rotating at high speed and high torque within the stationary chamber. Both sections are equipped with elliptical-patterned cutting heads and the waste is forced down through the chamber by the drum until it is ground into material for sizing in a rotating screening cylinder. The rotating screening cyclinder sizes and sorts the material into storage bins below with the aid of a fan to expedite the screening process. If the screened and sorted waste fills the compartmentized bins to capacity the system is stopped by electrical means.
