In fertilizer production, fertilizer crusher as a key equipment for early treatment, its grinding fineness has a crucial impact on the final effect of fertilizer, especially when it is linked with fertilizer pelletizer and organic fertilizer production line, this impact is more prominent.
The finer fineness of the grinding allows the raw material to have a larger specific surface area before entering the fertilizer granulator. Taking the organic fertilizer production line as an example, when organic waste such as livestock manure and straw is finely ground by the fertilizer crusher, the nutrients in it can be more fully exposed. In the subsequent fermentation process, microorganisms can decompose these substances more efficiently, accelerate the release of nutrients, make the fertilizer effect of organic fertilizers appear faster, provide timely and sufficient nutrients for crop growth, especially conducive to the rapid absorption of nutrients in the seedling stage and promote the development of roots.
From the physical level, the fine pulverized material has a higher particle uniformity when it is processed by the fertilizer granulator. Because small and uniform material particles are more likely to be closely combined in the granulation process, the formation of regular size and compact texture of fertilizer particles. Such fertilizer particles in the application of soil, water absorption, better fertilizer retention, not easy to cause nutrient loss due to soil erosion, continuous delivery of nutrients for crop growth, extend the validity of fertilizer, reduce the number of fertilization, reduce agricultural production costs.
However, the fineness of the grinding is not the finer the better. Excessive crushing will increase energy consumption and equipment loss, which does not meet the requirements of production cost control. And too fine materials are easy to caking during storage, affecting the smoothness of subsequent feeding in the fertilizer granulator, and even blocking equipment and interrupting production. Therefore, accurately control the fineness of the fertilizer crusher to make it perfectly fit with the fertilizer granulator and organic fertilizer production line, and find the “golden fineness” according to the characteristics of different raw materials and the needs of fertilizer varieties, which is the key password to improve the quality of fertilizer and help agricultural harvest.
