  • Publication number: 20080245913
    Abstract: An impact mill including a base portion on which is disposed a rotor rotatably mounted in a bearing housing, the rotor having an upwardly aligned cylindrical surface portion coaxial with the rotational axis. The impact mill is provided with a mill casing within which is located a conical track assembly which surrounds the rotor to form a conical grinding path. The mill casing is provided with a downwardly aligned cylindrical collar which may be axially adjusted to set a grinding gap between the rotor and the mill casing. The rotor is provided with a plurality of impact knives complementary with a plurality of impact knives disposed on the inside top surface of the mill casing. In addition, the impact mill can be formed of separated conical sections. Finally, power is transmitted to the rotor of the impact mill by a synchronous sprocketed belt, accommodated by a sprocketed drive sheave, wherein the belt is in communication with a power source.

  • Publication number: 20080185466
    Abstract: A solids reduction processor has a pair of opposed parallel rotor assemblies which are rotationally driven in opposite directions to pulverize solids dropped into the processor. Each assembly comprises a shaft, disc sets removably secured to the shafts, and circumferentially spaced sets of outwardly projecting hammer members removably secured to the disc sets for limited pivotal movement relative thereto. Operational abrasion of the shafts and discs is substantially reduced by virtue of the hammer sets on each rotor assembly being axially aligned with the hammer sets on the other rotor assembly. Additionally, since all of the discs from may be removed from their shafts, individual discs may be replaced without the necessity of replacing the whole rotor assembly. Particle reduction efficiency within the processor housing is increased by the use within the processor housing of top and side-mounted breaker bars having particle impact surfaces sloped both horizontally and vertically.

  • Patent number: 7401746
    Abstract: An improved design for hammermills. The invention contains a centered rotor from which eight rows of hammers pulverize material against cutting plates inside a working chamber. The cutting plates have slots that are angled. The hammers may have a beveled, angled leading edge. Both the angled cutting plate slots and the angled hammer leading edges work to drive the material through the working chamber in a helical fashion, with a preferred travel profile of 450 degrees, but the helix length is adjustable depending on the specific needs. There are no perforated screens in the hammermill, thus the material is placed in an inlet, is urged through the hammermill by the action of the rotating hammers where the material is comminuted and then removed via an exit.

  • Patent number: 7318527
    Abstract: An apparatus (100, 100?, 100?) for separating organic material from inorganic material includes a container (1), a feeding apparatus (4), a charging apparatus (9), a lifting apparatus (21), a discharging apparatus (24) and a removal apparatus (7). The feeding apparatus (4) is located in the upper portion of the container (1), and it serves to introduce inorganic material polluted with organic material into the container (1). The charging apparatus (9) is located in the lower portion of the container, and it serves to introduce cleaning water into the container (1). The lifting apparatus (21) is located in the container (1), and it serves to substantially subject the inorganic and organic material to an upwardly directed component of movement. The lifting apparatus (21) and the charging apparatus (9) produce a fluidized layer (22) in the container (1) during operation of the apparatus (100, 100?, 100?). The fluidized layer (22) causes the organic material to be separated from the inorganic material.

  • Patent number: 7314190
    Abstract: A method and apparatus for biological and/or chemical decomposition of waste containing organic matter. The method includes waste pretreatment in which waste is fragmented and homogenised in a pretreatment apparatus (10a, 10b) operating on the principle of a multi-ring double action impact mill. The apparatus has either two rotors (62, 64) or a rotor and stator disposed inside a housing (26), which rotors and/or stator are equipped with blades having impact surfaces, and which form one or more rings (1,2,3, . . . ) coaxial with the rotor. The waste is fed into the housing through the hub of rings formed by the blades, and travels by the effect of a rotor or rotors, to the outer ring of the ring (7) formed by the outermost blades, and further to the discharge opening (25, 27?) at the outer ring.
