NPK fertilizer and Compound Fertilizer Plants Supplier China 1, 30,000 Tons/year Compound Fertilizer Production Line - http://goo.gl/zx3Awf As roll extrusion granulator is widely used in many industries, such as compound fertilizer factories,chemical enterprises, feed mills, metallurgical industries, it’s a strong performer in compound fertilizer production line when being used to manufacture compound fertilizer of different concentration, including organic fertilizer, inorganic fertilizer, bio-fertilizer, and magnetic fertilizer. Especially, its application in making compound fertilizer with tombarthite, ammonium bicarbonate, ammonium sulfate is filling a domestic gap in this field. This compound fertilizer making system has low demand on formula. Steam whose pressure is in 4-6kpa, is introduced into rotary drum granulator, then being mixed with powder Phosphorus, Potash or other Nitrogenous manure, conditioning agents for further granulating. The steam melt the surface of N to make N bind with other raw materials. This compound fertilizer production line would be particularly applicable in high N compound fertilizer. It can produce all kinds of fertilizer, concentration varying from 25% to 48%. Due to the moisture content of materials being 3-5% during granulation, the drying capacity improves by 20%-40%, which greatly increase fertilizer production and decrease consumption.
