In this article,brief introduction of complete equipment and process of compound fertilizer production line of Zhengzhou Huaqiang Heavy Industry Technology Co.Ltd.The npk fertilizer manufacturing process production of compound fertilizer is the general process of compound fertilizer production,which is of great significance for users to incest and fully understand the production of compound fertilizer.
The fertilizer manufacturing process of npk,compound fertilizer is roughly as follows:raw material proportioning,mixing,and stirring,agglomeration and crushing,material granulation,primary screening,particle drying,particle cooling,secondary grading of particles,coating of finished particles,quantitative packaging of finished particles,etc.
The following is a detailed introduction to each link of the production process of npk, compound fertilizer and in different producing parts it is equipped with different type fertilizer equipment:
The production process of npk,compound fertilizer includes raw material promoting,mixing,crushing and agglomeration,granulation,primary screening,particle,drying,particle cooling,secondary screening,particle coating of finished products and quantitative packaging of finished products.
1.Raw materia ingredients:generally the raw materials can be the urea,ammonium nitrate,ammonium chloride,ammonium sulfate,potassium chloride and other raw materials can be selected and prepared in a certain proportion.
2.Mixing parts:Minx the prepared raw materials evenly to improve the overall uniform fertilizer efficiency content of the fertilizer particles,and use the horizontal mixer or disc mixer to mix the raw materials.
3.Agglomerate crushing:the raw materials with uniform mixture are crushed to facilitate the subsequent granulation processing,mainly using chain crusher,etc.
4.Material granulation:evenly stirred and crushed materials are sent to the granulator by belt conveyor for fertilizer granulator machine(drum granulator,disc granulator and roller press granulator can be used),which is an essential and most important step in the production process of compound fertilizer.
5.Primary screening:preliminary screening of semi-finished particles.Unqualified particles are returned to the mixing and mining link for reprocessing.Generally,roller screener is used to sceeen the granulator.
6.Particle drying:the particles made by the granulator and screned by the first stage are sent to the dryer to dry the moisture contained in the particles,so as to increase the particle strength and facilitate the storage.Generally,the rotary dryer is used in the fertilizer manufacturing process.Sometimes,the series of fertilizer dryer is also equipped in the organic fertilizer production line.
7.Particle cooling:the dried fertilizer particles are easy to agglomerate due to their high temperature.After cooling,they are easy yo be stored and transported in bags and stored by a cooler.
8.Secondary grading of particles:The cooled particles are graded,the unqualified particles are crushed and regranulated,and the qualified products are screened out,which can be screened by the secondary drum screener machine.
9.Finsihed paticle coating:coating the qualified products to increase the brightness and roundness of the particles,so as to make the appearance more beautiful.Generally,the coating machine is used for coating.
10.Quantitative packaging of finished particles:the coated particles,which is to easy,the finished particles are sent to the silo by the belt conveyor for temporary srotage,and then connected to the electronic quantitative packaging scale,sewing machine and other automatic quantitative packaging and sealing bags,placed in the ventilation place for storage,so as to realize full automation.
Then production process of compound fertilizer is simple,the production process of npk, compound fertilizer production line is small,the floor area is small,the operation is simple,and the technical requirements are not high.
