For the organic fertilizer production line, the early preparation of raw materials is the foundation. All kinds of organic waste, such as livestock and poultry manure, crop straw, etc., through fermentation, impurity removal, crushing treatment, so that its particle size is moderate, water content is maintained at about 25%-30%, which is the premise of efficient operation of disk granulator. Then, the treated material is evenly spread on the rotating chassis of the disk granulator, and the rotation speed of the disk is generally controlled at 8-12 RPM by adjusting the rotation speed of the disk, so that the material gradually forms spherical particles under the action of centrifugal force and friction. At the same time, an appropriate amount of water is sprayed on the top of the disk to humidify and assist particle forming, ensuring uniform material distribution and appropriate thickness in the whole process, and the molding rate can be greatly improved.
In the NPK fertilizer production line, the disk granulator is also showing its skill. Since NPK fertilizer has strict requirements on the ratio of nutrients, it is necessary to accurately measure the ratio of nitrogen (N), phosphorus (P), potassium (K) and other raw materials before feeding, and the common N:P:K ratio is 15:15:15 or customized according to the needs of crops. Then, the mixed powder raw materials are continuously added to the disk granulator according to quantitative, the disk Angle is adjusted to 30° -45 °, and the material is constantly turned by the copying plate to promote the uniform growth of particles. During this period, the shotcrete system is turned on and the aqueous solution containing the binder is sprayed on the material to enhance the particle strength and prevent breakage. Continuous monitoring of particle size, timely screening and grading, unqualified material returned to re-granulation, to ensure that the finished particle diameter of 2-4 mm, to meet market standards.
In short, whether it is organic fertilizer or NPK fertilizer production, mastering the correct use of disk granulator can jump out of the efficient and high-quality "production dance" on the stage of fertilizer production, and build a solid foundation for agricultural harvest.
