Description
本发明涉及钙镁磷肥圆颗粒生产制造问题，尤其涉及到钙镁磷肥崩解问题，属于肥料制造领域。The invention relates to the production and manufacture of calcium magnesium phosphate fertilizer round particles, in particular to the disintegration problem of calcium magnesium phosphate fertilizer, and belongs to the field of fertilizer manufacture.
钙镁磷肥属于一种砂型玻璃体肥料，由高温制造而成，含有大量中微量元素，但是由于钙镁磷肥独特的化学组成与水泥的性质相对接近，所以钙镁磷肥拥有水泥的特性，钙镁磷肥一旦激活水泥的特性制造成为颗粒后很难崩解开来，当钙镁磷肥崩解不开肥料的利用率将会大幅度降低。Calcium magnesium phosphate fertilizer is a kind of sand-type vitreous fertilizer. It is made at high temperature and contains a large amount of medium and trace elements. However, because the unique chemical composition of calcium magnesium phosphate fertilizer is relatively close to the properties of cement, calcium magnesium phosphate fertilizer has the characteristics of cement. Calcium magnesium phosphate fertilizer Once the characteristics of cement are activated and made into particles, it is difficult to disintegrate. When the calcium magnesium phosphate fertilizer cannot be disintegrated, the utilization rate of the fertilizer will be greatly reduced.
钙镁磷肥作为碱性肥料，对调节土壤的PH，补充中微量元素，由于粉剂钙镁磷肥使用不方便一直以来被大家所忽视。后来制造成为颗粒状钙镁磷肥由于崩解问题发挥不出钙镁磷肥的效果，所以一直都没有广泛被推广。As an alkaline fertilizer, calcium magnesium phosphate fertilizer can adjust the pH of the soil and supplement medium and trace elements. Due to the inconvenient use of powder calcium magnesium phosphate fertilizer, it has been ignored by everyone. Later, it was manufactured into granular calcium-magnesium phosphate fertilizer because of the disintegration problem, which could not exert the effect of calcium-magnesium phosphate fertilizer, so it has not been widely promoted.
本发明通过将盐类物质融合进钙镁磷肥颗粒中使钙镁磷肥拥有可以部分溶解的物质，当钙镁磷肥颗粒中可溶解性物质被溶解完后将会使颗粒结构发生崩塌最后导致钙镁磷肥出现崩解的的情况。In the present invention, the calcium magnesium phosphate fertilizer has a partially soluble substance by fusing salt substances into the calcium magnesium phosphate fertilizer granules. When the soluble substances in the calcium magnesium phosphate fertilizer granules are dissolved, the particle structure will collapse and eventually lead to calcium magnesium phosphate fertilizers. Phosphate fertilizers are disintegrated.
专利CN113200779A一种钙镁磷肥崩解剂及其应用中使崩解剂含量少且由于水溶性问题只能加入少量助剂导致颗粒在放置较长一段时间后出现不崩解的情况。Patent CN113200779A A disintegrating agent for calcium magnesium phosphate fertilizer and its application, the content of the disintegrating agent is small and only a small amount of additives can be added due to the problem of water solubility, so that the granules do not disintegrate after being placed for a long period of time.
专利CN110803959A一种生产圆颗粒钙镁磷肥的专用造粒剂及用途利用粘性物质将粉末状钙镁磷肥粘结成颗粒，使用这种方法制作出来的钙镁磷肥在长时间放置后会出现不崩解的情况。Patent CN110803959A A special granulation agent for producing round granular calcium-magnesium phosphate fertilizer and its application Use viscous substances to bond powdered calcium-magnesium phosphate fertilizer into granules. The calcium-magnesium phosphate fertilizer produced by this method will not collapse after being placed for a long time solution situation.
专利CN113200778A一种钙镁磷肥造粒剂及其应用主要针对的是钙镁磷肥造粒难的问题，专利CN103787796A一种颗粒状的酸性或酸化土壤调理剂及其制备方法，主要针对钙镁磷肥造粒困难的问题，本方法无法解决钙镁磷肥水泥化问题。Patent CN113200778A, a calcium-magnesium phosphate fertilizer granulator and its application are mainly aimed at the problem of difficult granulation of calcium-magnesium phosphate fertilizer.

Calcium magnesium phosphate fertilizer is also a kind of citrate-soluble fertilizer. When producing citrate-soluble granular fertilizers, magnesium sulfate mainly increases the particle strength, and at the same time It will also affect its disintegration.
