Analysis on five innovative technologies of NPK fertilizer production linePosted by tianci on February 20th, 2020 The granulation methods of domestic NPK fertilizer production line mainly includes disc granulation, steam drum granulation, spray coating granulation, tower melt granulation, acid neutralization granulation, and ammoniated drum granulation. The above fertilizer granulator machine is mainly applicable to large-scale compound fertilizer production in addition to disc granulator machine. Relative equipment investment is large, construction time is long, energy consumption is high, production costs are high, and certain environmental pollution problems exist. Extrusion granulation production the multi-element potassium sulfate magnesium fertilizer device has a small floor area, short process flow, convenient equipment operation, low construction investment and short construction period. Therefore, this compound fertilizer production line technology project is a short, flat and fast construction project, which has certain promotion and application value in small-scale compound fertilizer equipment manufacturers. 2. The traditional compound fertilizer production line adopts the slurry method or the humidified pellet method, which requires granules to be introduced before the granulation. In the fertilizer manufacturing process, a large amount of energy is consumed to dry the moisture, which results in a large amount of waste gas and waste water. , Waste residue, polluting the environment. Extrusion granulation of a compound fertilizer production line is the extrusion of materials by external force. No steam is required during the granulation process, which can save investment in boiler construction and coal production costs. The compound fertilizer production line has no moisture introduction and no drying process in the entire production process, eliminating the large and expensive dryer in the traditional compound fertilizer production line device, and can use the fuel and drying equipment for drying. The power consumption is saved, so the process of this compound fertilizer production line meets the needs of today's energy-saving society. Like it? Share it!More by this author |
