What types of NPK fertilizer granulators are available?
NPK fertilizer granulators are core equipment in the production of nitrogen, phosphorus, and potassium compound fertilizers. Different granulation processes correspond to different models, adapting to different production scales, raw material characteristics, and product requirements. Currently, there are four main models in the industry, each with its own advantages and disadvantages, covering all scenarios from small workshops to large-scale production lines. They precisely solve the core need of "converting powdered raw materials into granules," helping to improve fertilizer quality and production efficiency. The rotary drum granulator is the most widely used wet granulation machine, suitable for small and medium-sized fertilizer plants. Its core principle is to use the rotation of an inclined drum, through centrifugal force and gravity, to make the moist NPK raw material tumble and agglomerate inside the drum, gradually forming uniform granules. This model has a simple p...
