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.

Abstract: A vegetation shredder includes an elongated shaft to which a Frisbee-like disk element is attached downwardly facing and extending over a fastening collar to which elongated shredding tie elements are fastened around the periphery. The disk includes a downwardly extending peripheral rim which assists in creating a vacuum chamber between the disk and the shredding elements into which leaves are drawn.
Abstract: A chain beating type crusher includes a crusher vessel (3), a shaft (7) provided centrally thereof and capable of being rotated at a high speed, and a plurality of beating chains (11) provided in a plurality of axially spaced-apart stages in each of which a plurality of radially spaced-apart chains are formed on the shaft. With high speed rotation of the shaft the beating chains in the individual stages are caused to undergo high speed revolution to form respective bearing zones. In order to return an object scattered toward the inner surface of a peripheral wall (4) of the crusher vessel back to the beating sone, a plurality of guide members (15) are mounted on the inner surface and each have a surface inclined toward the beating zones in the direction of revolution of the beating chains. The beating chains are mounted on the shaft such that they are each positioned in correspondece to the mid position between adjacent ones of them in the next stage.
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.
Abstract: A drum conditioner which is capable of providing an external force on a drum so as to crack and loosen powdered or other finely divided material therein which has solidified and hardened is disclosed. The drum conditioner includes two pairs of pressure rollers which provide pressure to the drum and help rotate the drum as it sits on a conveyer bed of rollers. The pair of pressure rollers in the rear are adjustable so as to accommodate different size drums. The front pair of pressure rollers are provided with a hydraulic cylinder to assist in providing and maintaining pressure between the pressure rollers and the object drum, regardless of the regularity of shape of the drum.
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.

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.
