Granular fertilizers with uniform particle size, rounded appearance and good dispersibility are easy to gain the trust of users in agricultural production, and are convenient for transportation and mechanical fertilization. Good granular fertilizer has good effect and high value. So how to improve the granular quality of NPK fertilizer production?
The ratio of raw materials in NPK fertilizer production has great influence on fertilizer efficiency, and the appearance of granules is determined by the fertilizer granulator machine. The quality of compound fertilizer products can be greatly improved by controlling the two links of proportioning and granulation.
The roundness of compound fertilizer granules is also a quality index that every fertilizer factory attaches great importance to. At the same time, whether the compound fertilizer granules are regular in appearance, uniform in size, uniform in color, transparent in granules and so on have also become the user's criteria. Therefore, granular structure is one of the important indexes in the production and application of NPK compound fertilizer. The choice of granular products is spherical fertilizer granulator machine, which is very helpful to improve product quality.
Different nutrient allocation ratios of compound fertilizers have different effects on increasing yield and income. The fertilizer efficiency and economic benefit of NPK compound fertilizer with different ratios are different in agricultural production, and the benefit of NPK compound fertilizer is also different. Rational mixing of NPK fertilizer production line and compound fertilizer can greatly improve crop yield and economic benefits. The yield increase of compound fertilizer combined with NPK three elements is remarkable, which is higher than that of single fertilizer or two of them. Scientific formula fertilization of nitrogen, phosphorus and potassium improved the irrational fertilization structure and coordinated the growth and development of crops and the supply and demand of soil nutrients, so as to increase yield, improve quality and economic benefits.
