喷吹式连续放料，粗肥粒径９５％ 在２ ｍ ｍ 以下。经过标准分析方法对照及模拟土壤环境条件实验，证明粗肥不经过磨细，磷的有效性不受影响，达到一次淬细成肥。可采用无球磨的工艺，取得降低能耗和成本，防止污染的多重作用，粗粒钙镁磷肥特别适于水田施用。 Spraying continuous discharge, coarse fat particle size 95% below 2 m m. After the standard analysis method control and simulation of soil environmental conditions experiment, proved that coarse fat without grinding, the validity of phosphorus is not affected, to achieve a quenching into fat. Can be used without ball milling process, made to reduce energy consumption and cost, to prevent the multiple effects of pollution, coarse-grained calcium magnesium phosphate fertilizer is particularly suitable for paddy fields.
