粒状复混肥在水中的漂浮及其防止

Flotation of Granular Compound Fertilizers on Water and its Prevention

针对粒状复混肥料在水中易漂浮的特点,分析了引起漂浮的原因。为防止颗粒肥料的漂浮,工厂在生产颗粒肥料时可采用细粉原料造粒,避免高温而用低温长时间干燥,尽量使颗粒密实以减少空隙,或增加非水溶物含量。

In line with the characteristics of the liability of granular compound fertilizers to float on water, an analysis is made of the causes for their flotation. In order to prevent their flotation, granulation with pulverized raw materials can be carried out in the production of granular fertilizers in the plant, high temperature is to be avoided, drying is to be done at a low temperature for a longer time, and the granules are to be made as dense as possible or the content of non-water soluble substances is to be increased.
