Powdery phosphorite forming method for producing calcium magnesium phosphate fertilizer
The invention discloses a powdery phosphorite forming method for producing a calcium magnesium phosphate fertilizer, which comprises the following steps: preparing a powdery binder: fully mixing sodium silicate with the fineness of 50-200 meshes, sodium humate and bentonite according to a certain proportion to obtain the powdery binder; fully mixing the powdery phosphorite with a certain proportion of powdery binder to obtain a powdery phosphorite mixture; spraying a certain amount of phosphoric acid or phosphoric acid sludge acid liquid binder into the powdery phosphorite mixture, and fully and uniformly mixing to obtain a mixed material to be processed; and extruding the mixed material, standing and aging for more than 24 hours, and screening to obtain the formed phosphorite with the particle size of 10-100mm, high temperature resistance of 1300 DEG C and compressive strength of 100-300N. The powdery binder and the liquid binder are used together, so that the cohesiveness is good, and the prepared formed phosphorite is high in high temperature resistance, environment-friendly and high in compressive strength.
本发明公开了一种用于生产钙镁磷肥的粉状磷矿成型方法，按以下步骤进行，粉状粘结剂制备：将细度为50‑200目的硅酸钠、腐植酸钠、膨润土按照一定比例进行充分混合，得到粉状粘结剂；然后将粉状磷矿与一定比例的粉状粘结剂充分混合得到粉状磷矿混合物；在粉状磷矿混合物中喷洒入一定量的磷酸或磷酸渣酸液体粘结剂，充分混合均匀，得到待加工混合物料；将此混合物料经挤压、放置陈化24小时以上、筛分，得到粒径10‑100mm、耐高温1300℃，抗压强度为100‑300N的成型磷矿。粉状粘结剂、液体粘结剂一起使用粘结性好，制得的成型磷矿耐高温性强，环境友好，抗压强度高。
