Building an npk production line requires a compound fertilizer granulator. There are many compound fertilizer processing and granulation equipment. Some companies do not know how to choose a suitable compound fertilizer granulator. What is the compound fertilizer granulation equipment introduced today? There are three main types of compound fertilizer granulator: drum granulator, disc granulator and double-roller granulator. What is the difference between these compound fertilizer granulators? What are the advantages and disadvantages of each method?
The disc granulator mainly uses the rolling of the disc surface and the granulation of the granules themselves, and is used together with the upper mixer to achieve a high spheroidization rate. The investment cost of granulator equipment is low, and the production capacity is strong, but the dust of open-air granulation is relatively large.
The barrel of the drum granulator equipment is lined with a special rubber plate or an acid-resistant stainless steel lining to realize automatic scar removal and tumor removal, eliminating the traditional scraper device. A drum granulator is a forming machine that shapes materials into specific shapes.

The main working method is granule wet granulation. With a certain amount of water or steam, the basic fertilizer can fully react after being humidified in the tank. Under certain liquid phase conditions, with the help of the rotating motion of the cylinder, the extrusion force between the material particles condenses into balls. The investment cost of chemical fertilizer equipment is high, the production capacity is strong, and the dust of drum granulation is relatively small.
The double-roll granulator adopts non-drying normal temperature process to produce, one-time molding. The equipment has low investment, quick effect and good economic benefit. The whole set of equipment is compact in layout, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no waste discharge, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product granulation rate is high. Various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.) can be produced.
