Which NPK fertilizer process is most suitable for potassium chloride and sodium chloride
NPK fertilizer production is a kind of fertilizer manufacturing process which makes the material into solid particles with specific shape, which is suitable for long-term storage of fertilizer. In the process of NPK fertilizer granulation, the roller press granulator is usually used to process the fertilizer. It can directly extrude the powder material into particles under normal temperature and humidity. Roller press granulator is commonly used in unit fertilizer and multi-element compound fertilizer based on ammonium bicarbonate, urea, ammonium chloride, ammonium phosphate, potassium chloride, etc.
The granulated fertilizer produced by NPK fertilizer production process has high strength, the double roller granulator does not need drying equipment, which can reduce the production cost to the minimum, and is suitable for the granulation processing of potassium chloride and sodium chloride. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields.
