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.

摘要： The apparatus is suitably disposed within a circular tank and comprises a stationary bridge, a feeding bell, a scraper, driving means, and an optional foam scraping means. The apparatus is characterized in that it has a centrally suspended rotating scraper, mounted from a central vertical shaft and driven by a drive which travels along the rim of the tank, and additionally has at least one rotating drive arm. The drive arm is connected at one end to the drive and at its other end to the feeding bell, which is supported by the shaft of the scraper. The feeding bell is preferably capable of vertical adjustment. The scraper is preferably provided with at least one row of a plurality of vertical stick-like members. A foam scraper is optionally attached to the drive arm. The apparatus additionally contains means for automatically raising or lowering the scraper. depending on the relative rotary momentum between the scraper and the rim drive.
