Claims (2)

1. Способ получения сложного NPK-удобрения с регулируемым соотношением питательных веществ, включающий разложение фосфатного сырья кислотой, добавку азотсодержащего компонента, нейтрализацию аммиаком, смешение NP-пульпы с хлоридом или сульфатом калия, грануляцию и сушку целевого продукта, отличающийся тем, что на смешение с солью калия подают NP-пульпу с pH 3,0-5,5, в качестве азотсодержащего компонента используют нитрат аммония, а компоненты берут в количестве, обеспечивающем массовое соотношение нитрат аммония: соль калия в целевом продукте не менее 1,6:1.1. A method of obtaining a complex NPK fertilizer with an adjustable nutrient ratio, including the decomposition of phosphate raw materials by acid, the addition of a nitrogen-containing component, neutralization with ammonia, mixing NP-pulp with chloride or potassium sulfate, granulation and drying of the target product, characterized in that it is mixed with potassium salt serves NP-pulp with a pH of 3.0-5.5, ammonium nitrate is used as the nitrogen-containing component, and the components are taken in an amount that provides the mass ratio of ammonium nitrate: potassium salt in the target product e less than 1.6: 1. 2. Способ по п.1, отличающийся тем, что массовое соотношение питательных веществ N:P2O5:K2O в удобрении регулируют в пределах 1-12:0,5-6:1 количеством добавляемого нитрата аммония и соли калия.2. The method according to claim 1, characterized in that the mass ratio of nutrients N: P 2 O 5 : K 2 O in the fertilizer is regulated within the range of 1-12: 0.5-6: 1 by the amount of added ammonium nitrate and potassium salt.
