摘要： There is disclosed a process for preparing fertilizers containing dicalcium phosphate from phosphates of mineral origin by mechanical activation. According to the invention grains larger than 5 mm of the sized or unsized starting phosphate compound of mineral origin are granulated up to a grain size of 1 to 4 mm, the granulated phosphate obtained is admixed with monocalcium phosphate and the phosphate crystals are activated by colliding the grains of the mixture at a speed of 70 to 120 m/sec.The fertilizer prepared according to the invention possesses numerous advantages over the known phosphate fertilizers from technological and applicational point of view as well.
