In last article,we have share about the advantages of the npk fertilizer production line,and the raw materials of the npk fertilizer production line.Now we share about the npk fertilizer manufacturing process in this article.
Using the fertilizer manufacturing process to make the npk,compound fertilizer granulator made the process of the fertilizer making become simple and high efficicney.We designed the npk fertilizer production line to make the compound fertilizer granulator.So what it is the process of compound fertilizer production process:
1.Automatic batching machine for compound fertilizer production line.Firstly,various materials are propoetioned as per the formula by the 4-10 bins batching machine,which can complete materials batching automatically with high accuracy and high efficiency,thus the quality of the fertilizer is ensured.After batching,the materials are conveyed to the mixer machine.
2.Mixer machine for compound fertilizer manufacturing process
We adopted automatic and continuous mixer machine in this compound fertilizer production line.The cycloidal reducer drives the main shaft to rotate,and in turn drives the agitating sprial.screw.With the stirring of agitating screw and small shovels on them,the raw materials are fully mixed.After mixing,the materials are discharged from the outlet at the bottom.The inner side of the  mixer can adopt polypropylene plate or stainless steel,which makes the materials not easily stickly,and abrasion resistance.
3.Double roller press granulator/Double roller compacting granulator for compound fertilizer production line
By the belt conveyor,the well mixed  raw materials are conveyed to the pan feeder,which feeds the materials evenly into the four roller press granulator or roller compaction granulator under the feeder through the hopper.By the counter-rotating hig pressure rollers,the materials are extruded into slices.The slices flow down to the crushing chamner under the press roller,where they are  crushed  by the crushing rollers and screened to get the required granular.The press rollers  which the fertilizer granulator machine adopt new type metal which is resistant to corrosion,wear and impact.
4.Rotary screening machine for compund fertilizer production line
By the belt conveyor,the granules from the extrusion granulator are sent to the rotary screening machine,wher unqualified granules pass through the screen aperature and discharge through the outlet at the bottom,then conveyed back to the pan feeder,while qualified granules flow out through the outlet  at the lower end of the machine and conveyed to the finished products warehouse.
5.Automatic packing machine for compound fertilizer production line

Through the finished products warehouse,the qualifitied granules are weighed and packed by the automatic packing machine.The unit consists of automatic weighing and packing machine,conveying device,sealing device and feeder,It has the features of high weighing precision,stable operation,low power consumption,and small land occupancy.
We are as the fertilizer machine manufacturers,we not only design the npk fertilizer production line,we also designed the organic fertilizer manufacturing process to make the organic fertilzier granulator,the bio fertilizer production line is designed for producing the bio fertilizer granulator.
