以黄磷渣为基础原料,以多种表面活性剂混合复配为复合黏结剂,通过圆盘造粒制备了一种的磷渣基颗粒肥料。性能检测结果表明,产品具有较高的颗粒强度,平均强度为48.34 N,强度大于35 N的比例为93%;浸水实验结果表明,产品具有快速的水散性,在20 min内通过2 mm标准分样筛的比例为94%;成本分析结果表明,产品主要原料成本可控制在200元/t内。
Based on the yellow phosphorus slag as the raw material, a variety of surfactants were mixed and compounded into a composite binder, and a phosphate-based granular fertilizer was prepared by disk granulation. The results of performance test showed that the product had higher particle strength, the average intensity was 48.34 N, and the intensity was higher than 35 N, the ratio was 93%. The result of immersion test showed that the product had rapid water dispersity and passed 2 mm standard The proportion of the sample screen is 94%. The cost analysis shows that the cost of the main raw materials can be controlled within 200 yuan / t.
