npk fertilizer manufacturing process
The process technology of N-P-K fertilizer is advanced and reliable. According to the compatibility and crossability of the three raw materials, N-P-K compound fertilizer in different percentage composition can be manufactured applicable for different requirements of soils and crops.
Mixing Process for npk fertilizer production line: the raw materials are put into mixer in strict accordance with the technical requirements of each raw material quantity. Then the conveying belt sends the materials to crushing machine.
Crushing Process for npk granular fertilizer production line: the crusher machine smashes lump materials into small ones that the fineness meets the required for granulation. Then the conveyor belt sends the materials to rotary drum granulator machine.
Granulating Process for npk fertilizer production line: there is a water pump to offer gas or steam and makes fertilizer particles forming easily. The solid fertilizer powder after granulation will rise by the rotation of the cylinder and scroll down under the effect of gravity. At the same time, according to the raw material quantity, add a certain proportion adhesives for granulation. After several times repetition of the same rotation, fertilizer materials gradually form. Next the conveying belt sends the materials to rotary drum drying machine and cooling machine.
Drying & Cooling Process npk fertilizer production line:There are also draught fans to supply hot air and cold air to rotary dryer machine and rotary coolermachine respectively. After drying and cooling is screening process. the coating machine can beautify the materials and keep the effect of the finished product .
Screening Process for npk fertilizer production line: the qualified materials can be sent to packaging machine by bucket elevator, while others are conveyed back to crusher or granulator to be re-processed.
Fertilizer Coating Machine fornpk fertilizer production line: The conveyor belt sends the qualified granules from the second screen into the rotary coating machinefrom the higher end. With the rotation of the cylinder, powder or liquid are evenly coated on the surface of granules, which prevent caking, meanwhile increase the brightness and roundness of the granular. The machine is lined with polypropylene plate or stainless steel plate.
How to Produce the High Nitrogen NPK Compound Fertilizer?
To produce high nitrogen compound fertilizer, one important equipment is needed in the granulating process: the spraying system. The melting tank melt the urea and then spray the melted liquid into the granulating machine so that it will mix with powder phosphate fertilizer, potash fertilizer and other nitrogen fertilizer. Then with the help of the granulator, the liquid and other raw materials will be mixed and granulated. This production technology is used to produce compound fertilizer or complex fertilizer with high nitrogen content from 25%-45%.
