    摘要: Waste tyres (76) are disposed of in a cement-manufacturing or other mineral-burning process by introducing the tyres into the hot gas stream (82) at at least one point between the mineral-inlet end of a rotary kiln (2) and the lowermost cyclone (36) of an associated preheater system, e.g. into the gas stream (82) within a precalciner vessel (24) or riser duct (32), the tyres being maintained in contact with the hot gas for a sufficient period to effect at least partial combustion of the tyres. As an alternative, the tyres may be introduced into a Lepol grate preheater (84).

    摘要: Particles having different properties (e.g. particulate fly ash and carbon) are separated by driving the particles by means of a vibratory feeder (12) forwards along a horizontal electrode plate (1) above which is mounted a second electrode (2) having at least one plate (4) mounted at an acute angle (a) to the horizontal. Preferably, two plates (4) each extend sideways from a central block (3) of dielectric material. An alternating electric field is generated between the electrodes (1, 2) by a high voltage AC power source (14). The potential across each plate (4) varies (in particular, decreases) in the lateral direction, the variation being continuous or stepwise. The field lines (16) from each plate (4) curve to the side and impart centrifugal forces to particles charged by friction or conductive induction, which forces separate lighter, more heavily charged particles from the others. The separated particles are collected in bins (13) arranged around the lower electrode (1).

    摘要: A settable cementitious composition is prepared by mixing a ground mineral clinker that contains the phase 4CaO.3Al₂O₃.SO₃ with a source of SO₃ (eg. calcium sulfate), a source of CaO (eg. lime and/or ordinary Portland cement) and a fibrous material, in the presence of water. The fibrous material, which is preferably selected from synthetic organic fibres, wollastonite fibres and mixtures thereof, gives rise to improvements in the strength characteristics of the hardened masses formed by the setting of the compositions. The compositions find use in the production of monolithic packs to be used as supports in underground mining operations and also in the production of ceiling tiles and similar constructional articles.

    摘要: A cementitious composition comprises (a) an hydraulic cement comprising at least 65% by weight of hydraulic calcium silicate, e.g. tricalciuin silicate, and (b) a water-soluble or water-dispersible organic polymer. The hydraulic cement preferably comprises not more than 7% by weight of Al 2 O 3 , not more than 6% by weight of Fe 2 0 3 and not more than 4% by weight of S0 3 , and may be partially replaced by a mineral aggregate or extender. The polymer is present in an amount of up to 15% by weight of the cement and other mineral components and is preferably a partially hydrolysed poly(vinyl acetate). The compositions are rendered settable by the inclusion of water, the set products having excellent wet dimensional stability.
