  • Patent number: 9283594
    Abstract: A disc screen includes a shaft, a first disc mounted on the shaft, and a second disc mounted on the shaft. An interfacial opening (IFO) extends between the first disc and the second disc. A width of the IFO as measured between the first disc and the second disc varies according to a rotational position of the shaft.
    Type: Grant

  • Patent number: 8424684
    Abstract: A material separation screen includes multiple shafts mounted on a frame. Multi-diameter disc assemblies are mounted on the shafts and are configured to rotate and separate out different types of materials from a material stream. The multi-diameter disc assemblies include spacer discs that separately interlock together around the shafts. Compound discs are separately attached to the shafts next to the spacer discs. The spacer discs are made from a harder material than the compound discs to reduce spacer disc wear and to reduce the amount of material needed for fabricating the multi-diameter disc assembly.

  • Publication number: 20090071377
    Abstract: The present invention relates to a hydraulic binder for low-cement content concrete. The ground mineral portion of this cement comprises an under-calcinated alumina the BET specific surface of which ranges between 8 m2/g and 20 m2/g. Said binder enables to formulate a concrete the use properties of which remain stable and constant whatever the type of silica fume used, and capable of being used over a wide working temperature range for implementation. The invention also relates to a preparation for refractory concrete, a refractory concrete and a method for making a refractory concrete.
