Comminuting Surface Deformable By Contact With Material Patents (Class 241/102)
  • Patent number: 9751087
    Abstract: A comminution mill is described that includes a vertically oriented cylindrical housing with an intake chute in a top wall and an outlet chute in a bottom wall thereof. A rotatable shaft with a plurality of radially extending cables is disposed coaxially within the cylindrical housing. A plurality of studs extends inwardly from the wall of the housing to slow and collect materials flowing through the comminution mill. The studs can be withdrawn to discharge materials collected thereon. Slits are provided in the walls of the housing to enable the exit of particulate materials from the housing. A hood is provided overlying the slits on the exterior of the comminution mill for collecting the particulate material.

  • Patent number: 9408397
    Abstract: The invention relates to a kneading apparatus for kneading and mixing dough, having a kneading chamber, discharge opening and an input. The kneading apparatus has at least two shafts to which tools which are arranged in the kneading chamber are fixed, wherein at least one of the tools is designed to convey dough from the input region, in the conveying direction, to the discharge opening. The rotation speeds of the two motor-driven shafts can be set and changed separately from one another with the aid of a control. The two shafts are fitted with tools in a different manner from each other in such a way that the conveying action of all the tools of one shaft differs from the kneading action of all the tools of the other shaft given the same rotation speed of the shafts in each case.

  • Patent number: 5586732
    Abstract: The invention was developed in order to effectively crush and disperse various samples easily and efficiently without using any expensive device. By laminating a polyethylene film 3, a net member 7, a net member 9 and a polyethylene film 5 in sequence and welding these members to one another at weld portions 13a and 13b, a bag member 15 is formed. Further by forming a fastener 17 in the vicinity of an opening 15a, a crushing and dispersing bag 1 is completed. After a sample and a dispersing medium are introduced through the opening 15a, the bag is sealed with the fastener 17. Subsequently, when the crushing and dispersing bag 1 is squeezed, the sample is ground by the file-like irregularities formed by the net members 7 and 9 on the inner surface of the bag 1.

  • Patent number: 5390861
    Abstract: A method and apparatus for processing discarded rubber tires and rubber tire material to reduce the same to a pulverulent form of sufficient quality fiber the manufacture of other articles. Principally the rubber tire is subjected to repeated compression against the metal strand component of the tires thus causing the metal stranding to cut into or chew the rubber into a pulverulent form. During the processing of the rubber tire material it is broken down to the point that its constituents such as metal fibers and polymer fibers are separated therefrom. The pulverized rubber, together with its separated constituents may then be classified and the constituents separated for further use. The rubber tire processing apparatus incorporates an external housing structure and a rubber processing drum that is rotatable therein.

  • Patent number: 4289279
    Abstract: A mill lining is disclosed, intended for e.g. a primary or autogenous mill in the mining industry. The lining comprises shell plates and lifter bars made from elastomer material and mounted in a mill drum. The lifter bars extend substantially in the axial direction of the mill drum and project into the mill drum beyond the inner surface of the shell plates. At least some of the lifter bars, preferably every second, are designed to act as elastomer springs by having a longitudinal recess or slot in their impact front side facing forwardly in the contemplated direction of rotation of the mill drum. The recess or slot is inside the inner surface of the shell plates and serves as a strain concentrator concentrating the tensile strain of the lifter bars to an area relatively unexposed to sliding abrasion of the material being ground.
