| 中文摘要:研究圆盘造粒和挤出-滚圆造粒2种方式制取复合肥造粒的工艺过程及其颗粒特性。比较这2种造粒工艺过程及颗粒特性差异性，用于优化颗粒成型方式，提高颗粒成粒率、改善颗粒外形、颗粒力学特性等，以便对复合肥颗粒有更深入的了解。结果表明：从测定颗粒特性的各项指标中可以看出，挤出-滚圆造粒由于有挤出和滚圆2个过程，所制作的复合肥颗粒致密度较高，稳定性好，圆度和流动性较好，粒径分布也比较均匀；圆盘造粒所制肥料颗粒粒度分布广，干燥速率高，肥料养分释放速度快。 |

| Abstract:We studied the fertilizer granulation processes and particle characteristics by use two ways such as disc granulation and extrusion, spheronization in the processing of granulating compound fertilizer,and compared granulation process and differences on particle characteristics for optimizing particle formation methods,improving particles into the grain rate, improving particle shape and particle mechanical characteristics, so as to understand fertilizer granules well. The results showed that two processes of extrusion- spheronization for extrusion and spheronization can produce compound fertilizer granules with higher density, good stability, roundness and fluidity, relatively uniform in particle distribution by measuring indicators of particle characteristics.Fertilizer particles by disc had wide particle size distribution, high drying rate and fertilizer nutrient releasing speed. |
