  • Publication number: 20090166457
    Abstract: A reliable, inexpensive option for the plates that function as wear parts and are mounted on an inner face of a casting wall of a stator. To achieve this the plates are designed as cast parts and are fixed to the inner face of the casting wall from an exterior of the stator. The plates are fixed by fixing bolts, which are screwed into the plates through the casting wall from the exterior. The plates have transverse threaded bores that correspond to the bolts. Respective spacer rings are pushed onto the fixing bolts secured by wedge-shaped cotters in both a positive and non-positive fit, and the wedge-shaped cotter pressing on the spacer rings that lie against the outer face of the casting wall. This invention is extremely economical and improves the operational safety in comparison to known options.

  • 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.

    Abstract: The invention concerns blow bar 1 for impactor rotors with a mirror-symmetrical longitudinal cross-section for the purpose of reversibility, which is fitted in peripheral recesses 17 of the rotor advantageously comprising discs 16. According to the invention, the cross-section of blow bar 1 essentially forms a basic double trapezium shape with the wide bases of each trapezium as symmetrical axis 2. The rear 5 of the blow bar corresponding to the height of each trapezium is arranged at rightangles to the symmetrical axis and forms a level surface 6 over the total height of the blow bar. The invention also specifies an advantageous rotor for such a blow bar, Fig.

  • Patent number: 5992405
    Abstract: A tool mounting block having a forward surface and a rearward surface and a cylindrical transverse aperture extending therethrough opening onto both the forward and rearward surfaces. The tool has a tapered forward cutting end, and axially aligned behind the forward cutting end is an annular flange. Axially aligned behind the annular flange is a cylindrical mounting portion adapted to sidably fit within a complementarily cylindrical aperture of the mounting block, and extending rearward of the cylindrical mounting portion is a threaded stud. At the forward end of the tapered cutting end is a seat into which a hardened metal insert is bonded. To retain the cylindrical mounting portion of the tool within the cylindrical aperture of the mounting block, a locking nut assembly is threaded on the stud. When a tool is retained in a mounting block by such a nut assembly, the nut may be tightened to prevent rotation of the tool within the mounting block.

  • Patent number: 5887808
    Abstract: A grinding apparatus optimizes grinding efficiency within the grinding chamber by providing grinding action over a 360.degree. range encompassed by a set of breaker bars and one or more arcuate screening elements. Arcuate screening elements have an inside radius that identically matches the inside radius of the breaker bars. The screening elements act as grinding mechanisms as well as more conventional filtering mechanisms due to increased grinding capacity when the inside radial surface of the screening elements and the inside radial surface defined by the breaker bars are equidistant from the axis of a rotational shaft that supports a plurality of circumferentially spaced hammers.

  • Patent number: 5854061
    Abstract: This invention relates to a method of accelerated remediation or bioremediation of contaminated material using an apparatus comprising means for generating a treated contaminated material entraining air stream at a velocity sufficient for entraining the contaminated material therein. The contaminated material is entrained in the air stream and is then microenfractionated using the apparatus to form a microenfractionated contaminated material. Finally, the microenfractionated contaminated material is treated with at least one chemical amendment and/or one biological amendment by discharging the chemical amendment and/or one biological amendment from the apparatus thereby facilitating the accelerated remediation or bioremediation. The chemical amendment can comprise either a chemical oxidizing agent or a chelating agent.

  • Patent number: 5829649
    Abstract: A machine for conditioning and dispensing loose fill insulation material, such as cellulosic insulation, fiber glass insulation and rock wool insulation. The machine includes a hopper, a conditioning chamber, an air lock and a blower for pneumatically dispensing the material. The conditioning chamber is equipped with three rotating shafts with helically arranged spikes which serve as conveyors as well as dispersers. A lower conveyor shaft moves the material toward the opening into the air lock, while the two uppermost conveyor shafts move the material in the opposite direction. Thus, the same assembly which conveys the material to the air lock also conditions the material. Moreover, the counter current flow pattern churns or agitates the insulation material while the individual spikes disperse it. A single motor drives the rotation of the conveyor shafts and the rotation of the vanes in the air lock.

  • Patent number: 5626298
    Abstract: A tub grinder for grinding animal feed and the like of the type having a hammer mill extending below a stationary floor about which a tub side wall rotates, incorporates a rear discharge opening formed in a rear side wall of the hammer mill and includes deflector plates extending across an end wall of the grinder for directing material out the discharge opening to the rear of the tub grinder. Shear plates are adjustably secured to an end wall of the hammer mill housing. The shear plates are oriented in overlapping and angled relationship with respect to one another and to prevent ground materials from accumulating on the shear plates particularly when wet. Sickle blades are retractably positioned in the mill side walls for providing additional cutting action. Further, hammer assemblies are modified to include a knife edge and a face plate.
