| 中文摘要 |
| 本文对用粉煤灰制肥料的可行性进行了研究,选用磷矿石、助熔剂,添加剂和粉煤灰以适当的比例混合后熔融,使混合物料中的非枸溶性成分转化成能被植物吸收的枸溶性成分。经上百次熔融实验,对物料的配比及工艺条件进行筛选,确定出最佳配料参数和工艺操作条件。所研制肥料的吃灰量可达40%,并具有复合肥的作用和较好的肥效。 |
| 英文摘要 |
| A feasibility study on manure manufacturing with fine coal ash was performed. After the apatite fluxing agent and additives were mixed with fine coal ash in appropriate proportion and melted, non-dissoluble components in the mixture were changed into dissoluble elements which could be absorbed by plants. The formulation of materials and technological conditions were screened through hundreds of fusion experiments and the optimal burden parameters and technological conditions were obtained. The content of the fine coal ash in the studied manure could reach to 40%. The manure has the function of compound manure and therefore has good effect on plant growth. |
