There are many ways to produce NPK compound fertilizer, and granulation is the basic operation in the production of various solid compound fertilizers. Agglomeration granulation is the most common way of NPK fertilizer granulation. Rotary drum granulator plays an important role in the factory-produced NPK fertilizer production line.
a.The structure of the drum granulator is simple.
b. Rotary drum granulator is suitable for many kinds of raw materials. It has a wide range of NPK fertilizer granulation conditions.
c. When the drum granulator produces NPK fertilizer, it is easy to observe the material condition and remove water vapor at the same time.
d. The rotary drum granulator has large volume, long drum and long material retention time. The granulation effect of NPK fertilizer production line is good.
e. Steam, ammonia, or phosphoric acid, sulfuric acid, urea ammonia solution can be added to the drum granulator. The utilization rate of reaction heat in the production of drum granulator is high, which improves the thermal efficiency and production efficiency of the whole process.
Structure and characteristics of rotary drum granulator
1 The machine shell of the drum granulator adopts special rubber or stainless steel lining plate, which can prevent material from jointing.
2 The granules produced by the drum granulator are spherical with high strength.
3 Rotary drum granulator is corrosion resistant, long service life, easy operation and maintenance.
We designed a Rotary Drum Granulation Production Line specially for NPK fertilizer production by drum granulator. According to the production capacity of drum granulator, the production line has different production capacity, and can produce at least 10,000 tons of NPK fertilizer per year. Rotary drum granulation production line can not only meet the production of NPK fertilizer, but also be used for large-scale treatment of organic fertilizer, compound fertilizer and other fertilizers.
