    • According to a method of producing a phosphate fertilizer, a first portion of the phosphate is produced in a pipe cross reactor, and a second portion of the phosphate is produced in a pre-neutralizer. Both the first and second portions of the phosphate are supplied to a granulator. Ammonia is added to the granulator to react with the first and second portions of the phosphate. To produce the first portion of the phosphate, a micronutrient is added to phosphoric acid to produce an enriched acid, and the enriched acid and ammonia are added to the pipe cross reactor where they are allowed to react to produce ammonium phosphate.
    • 根据磷酸肥料的制造方法,在管交叉反应器中制造磷酸盐的第一部分,在中和剂中制造第二部分磷酸盐。 将磷酸盐的第一和第二部分都供给造粒机。 将氨加入到造粒机中以与磷酸盐的第一和第二部分反应。 为了产生磷酸盐的第一部分,向磷酸中加入微量营养素以产生富集的酸,并将富集的酸和氨加入到管道交叉反应器中,在那里使其反应以产生磷酸铵。

    • This invention concerns a mine roof support of the kind comprising a floor beam, a roof engaging canopy and a plurality of extendible struts such as hydraulic jacks supporting the canopy from the floor beam. The invention comprises the provision of a flap pivotally connected along one edge of the canopy such that outward pivotal movement thereof may cause it to engage the canopy of an adjacent support. Hydraulic jack or equivalent means are provided acting between the canopy and the flap to urge the flap outwardly. The flap provides effective sealing of the gap between adjacent canopies in a line of roof supports and also enables each canopy to be positioned accurately between adjacent supports during advancing movement of the support.
    • 本发明涉及一种包括地板梁,屋顶接合罩和多个可伸展支柱(例如从地板梁支撑篷顶的液压千斤顶)的矿山屋顶支撑。 本发明包括提供一个沿顶盖的一个边缘枢转地连接的挡板,使得其向外的枢转运动可以使其与相邻支架的顶盖接合。 提供液压千斤顶或等效装置作用在顶盖和翼片之间以向外推动翼片。 翼片提供了在屋顶支撑线中的相邻檐篷之间的间隙的有效密封,并且还使得在支撑件的前进运动期间,每个顶盖能够准确地定位在相邻支撑件之间。
