The decisive role of screening accuracy on fertilizer quality

In the organic fertilizer production line, the raw materials still contain certain impurities and incomplete decomposition substances after fermentation and decomposition. At this time, the high-precision screening equipment is like a strict "quality inspector", which accurately removes impurities such as large undecomposed materials and plastic paper scraps, leaving only fine and uniform organic materials. These pure organic materials enter the subsequent process, and can form organic fertilizer particles with uniform particles and balanced nutrient distribution in the fertilizer granulator. If the screening accuracy is not enough, impurities are mixed, not only affect the appearance of the fertilizer, but also reduce the fertilizer efficiency, and may even have adverse effects on the soil and crops due to impurities carrying bacteria.

In the traditional fertilizer production line, different formulations of fertilizer raw materials are mixed and also rely on precise screening. For example, in the production of compound fertilizer, nitrogen, phosphorus, potassium and other raw materials are mixed proportionally, and only through high-precision screening can the nutrients be evenly distributed to each grain of fertilizer. After the particles produced by the fertilizer granulator are screened, the particle size of the qualified product is consistent, which is convenient for farmers to apply and can accurately control the fertilizer application amount. The unqualified large or small particles are screened out and can be re-broken or adjusted to ensure the stable quality of the listed fertilizer.

Although the fertilizer tiller has initially mixed materials in the flipping process, screening is the last line of defense for quality control. It works closely with the entire production line, from the organic fertilizer production line at the source, through the rough mixing of the fertilizer stacking machine, to the final fertilizer granulator after forming the fine screen, layer by layer.

In short, the level of screening accuracy directly determines whether the fertilizer is a quality product that helps the agricultural harvest, or a poor quality product that affects the growth of crops and damages the market reputation. Fertilizer manufacturers only pay attention to the screening link, in order to make high-quality fertilizer products stand out in the fierce market competition.
