Способ получения фосфорных удобрений, включающий разложение фосфатного сырья кислыми растворами с одновременным его измельчением и грануляцию продукта, отличающийся тем, что измельчение ведут в шаровой мельнице при частоте вращения барабана (0,3 - 0,8) nкр, где nкр - условная критическая скорость, и заполнении ее шарами при φ = 0,2 - 0,3, где φ - отношение Vш, занятого (до начала движения) шарами к общему объему барабана мельницы V, при этом процесс измельчения ведут в течение 45 - 90 мин.A method of producing phosphate fertilizers, including the decomposition of phosphate raw materials in acidic solutions with its simultaneous grinding and granulation of the product, characterized in that the grinding is carried out in a ball mill at a rotational speed of the drum (0.3 - 0.8) n cr , where n cr is conditional critical speed, and filling it with balls at φ = 0.2 - 0.3, where φ is the ratio of V W occupied (before the start of movement) by balls to the total volume of the mill drum V, while the grinding process is carried out for 45 - 90 minutes.
