  • Patent number: 9592482
    Abstract: A system for processing material has a power supply and a machine having a hopper for receiving and passing material to an auger. The auger has a shaft with an axis about which it rotates, a helical flighting mounted to the shaft, pins mounted to the helical flighting, and paddles mounted to the shaft. The radial outer edge of the helical flighting is crenelated with periodic notches that form rectangular blades on the helical flighting. The pins are rotationally and angularly aligned with leading edges of the rectangular blades. The system may include a vehicle, such as a trailer, having first and second compartments separated by a partition. The power supply is located in the first compartment and has a power supply member extending though the partition. The machine is located in the second compartment and coupled to the power supply member.

  • Patent number: 9066830
    Abstract: An apparatus for manufacturing an absorbent body includes: a sheet supplying mechanism for supplying a sheet from a sheet roll; a crusher for crushing the sheet into a fibrous matter by scraping a reeling-out tip end of the reeled out sheet; and a fiber stacking device for forming the absorbent body in a predetermined shape by laminating the fibrous matter to be sent out from the crusher. When switching a supply of the sheet to the crusher from one to another sheet supplying mechanism, at least two sheet supplying mechanisms supply the sheet to the crusher over a predetermined period including a period in which the one sheet supplying mechanism decreases a sheet reeling-out speed, in correspondence with the period in which the one sheet supplying mechanism decreases the sheet reeling-out speed, the other sheet supplying mechanism increases a sheet reeling-out speed.

  • Publication number: 20080302889
    Abstract: Sewage sludge that has been de-watered to 25% solids is subjected to a combination of shearing and heating that liquefies the sludge, and drops its viscosity to below 12,000 cP. The fact of liquefaction prepares the sludge such that subsequent drying can be done more cost-effectively than hitherto. After drying, the dried sludge can be incinerated.

  • Publication number: 20080296421
    Abstract: Blades on a rotating grinding plate force waste against a stationary grinding ring. The blades are mounted on radially aligned guides on the grinding plate, allowing the blades to move freely inwardly and outwardly between opposing stops. The blades are thrown outward by rotation of the grinding plate. A receding face on the blades cooperates with the grinding ring for moving the blades inwardly and for forcing waste against the grinding ring.

    Abstract: A high turbulence mill used for producing supermicro powder and nanomaterials includes: a driving device provided on a base; a hollow grinding casing having a toothed ring-shaped guide stator fixed to an inner circumference thereof; a bi-negative pressure turbine rotatably mounted within the grinding casing; a hopper for delivering materials into the grinding casing via a material feeding pipe; a material discharging pipe communicated with the grinding casing for discharging pulverized products; and a control device for electrically controlling the high turbulence mill. When the specifically designed bi-negative pressure turbine spins at a high speed within the grinding casing under the driving operation of the motor, strong vortexes and high turbulence will be formed in the grinding casing, and thus a gas-solid two-phase flow is formed.
