Raw Material Preparation: The Starting Point of Perfect Formulation
Everything begins with precise material ratios. Just as baking requires accurate measurement of ingredients, NPK fertilizer production starts by precisely weighing nitrogen (N), phosphorus (P), and potassium (K) materials according to the target formula. Subsequently, large chunks of raw materials are crushed into fine particles suitable for mixing by chain crushers, preparing them for subsequent processes.
Mixing and Granulation: The Art of Creating Uniform Pellets
When various materials dance in dual-shaft paddle mixers or V-type mixers, a feast of uniform blending begins. An appropriate amount of water is then added according to granulation needs, bringing the mixture to ideal humidity. At this point, equipment like disc granulators, rotary drum granulators, or extrusion granulators take the stage, shaping these mixtures into pellets of specific sizes and forms through rotation or pressure.
