There are a variety of processes for the NPK fertilizer production line
, such as the blending method, extrusion method, and amino acid method, which can produce compound fertilizers, and they have different characteristics. Take extrusion granulation equipment as an example to describe the characteristics of its production process.
When extrusion granulation equipment is used for production, generally the material is first extruded into a sheet of a specified thickness or pressed into pieces, and then crushed into granules. Sometimes the material is first pressed into strips or columns, and then crushed into granules.
The test proves that the selection of suitable raw materials and their proportions during production is an important factor in the production of high-quality extruded fertilizers. Some raw materials can be mixed and extruded at one time according to their respective characteristics.
There are still some materials that do not have such extrusion properties. This requires us to carry out an extrusion test before production, so that the relevant procedures and methods for processing materials can be obtained based on the test data.
The investment of extrusion granulation equipment is lower than other equipment, because the production process is shorter and less equipment is used. It does not require heating or humidification during production, which saves energy and investment. There is no waste gas or wastewater generated during production, which is safe and pollution-free. Because of its simple process, it is particularly simple and convenient to operate, which can better achieve production automatic control to improve production efficiency.
However, the extrusion granulation equipment also has a feature that it cannot complete large-volume production and its granule shape is not as good as that of compound fertilizer equipment such as drums and discs, and it is easy to generate dust during transportation.
Increasing the processing links in the production process can be avoided), these problems are all left to our Huaqiang compound fertilizer machine manufacturers
, just to ensure that we will provide you with reasonable and advanced compound fertilizer equipment.
