    • An apparatus and a method for removing unburned carbon from fly ash capable of suppressing facility cost and stably conducting performance adjustment depending on property of the fly ash. The method comprises the steps of: adding water to fly ash to produce slurry; adding collector to the slurry, feeding the slurry and the collector to a static-type mixer 4, a venturi pipe 24 or the like to add shearing force to them; adding frother to them to generate air bubbles; and adhering unburned carbon of the fly ash to the air bubbles to raise the unburned carbon. The frother and air can be fed to the static-type mixer or the like together with the slurry and the collector. Depending on the change in property of the fly ash, the number of the static-type mixers or the like used in series can be increased or decreased, and depending on required capacity, the number of the static-type mixers or the like used in parallel may be increased or decreased. The static-type mixer may comprise a guide vane chamber 4b with plurality of guide vanes 4d for converting the slurry and the like, which are fed to the chamber, to spiral flow, and a current cutter chamber 4c with plurality of mushroom-shaped projections 4e for adding shearing force to the slurry and the like.
    • 一种从粉煤灰中除去未燃碳的装置和方法,其能够抑制设备成本并且根据飞灰的性能稳定地进行性能调整。 该方法包括以下步骤:将水添加到飞灰中以产生浆料; 向浆料中加入收集器,将浆料和收集器输送到静态混合器4,文丘里管24等中以向它们增加剪切力; 给他们添加起泡产生气泡; 并将飞灰的未燃烧碳附着到气泡上以提高未燃烧的碳。 起泡剂和空气可以与浆料和收集器一起进料到静态混合器等中。 根据粉煤灰的性质的变化,可以增加或减少串联使用的静态混合机等的数量,根据所需的容量,使用的静态混合机等的数量 平行可以增加或减少。 静态混合器可以包括导向叶片室4b,其具有多个导向叶片4d,用于将供给到室中的浆料等转化成螺旋流;以及具有多个蘑菇状突起的当前切割器室4c 4e用于向浆料等添加剪切力。

    • A method of making frac sand having a selected grade from a naturally occurring, mined sand having a SiO2 content of at least about 80 percent and having a particle size range where the maximum particle size is less than about 8.0 mm, comprising: crushing the mined sand into an intermediate particulate material; screening the particulate material into a feedstock with particles having a particle size coarser than about 350 mesh and initial values for roundness and sphericity of the particles; passing the particles of the feedstock through a blast tube with an outlet to pneumatically abrade the particles and propel the feedstock in a stream under a given pressure from the outlet; directing the pressurized stream against a fixed target located at a given distance from said outlet to physically abrade the particles to form an output mass containing abraded particles: and, repeating operations (c) and (d) a number of times or process stages until the particles resulting from the repeatedly abraded output mass is a final output mass having both processed roundness and sphericity values of at least 0.6 and wherein the values are greater than the initial values of the feedstock by at least about 0.10 to 0.50.
