2, extrusion granulation is a common production method of non-binder compound fertilizer in our country. Intermolecular condensation crystallization, in the production process of organic fertilizer production line to play the role of adhesive. But in the drying process, the water must be discharged inside and on the surface of the particles, otherwise the fertilizer is easy to stick and caked in the storage process. Dry granulation does not need to add additional additives, only use the material itself intermolecular force, simplify the process, reduce energy consumption.
3. Less investment in organic fertilizer equipment is due to saving the drying process, low recovery rate (about 15% of the total feed amount of the extruder), simple process flow and less investment.
4. There are more than 20 kinds of materials successfully used for extrusion granulation, such as ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc., extrusion granulation process can be processed flexibly in a short time for a period of time. Achieve product formula replacement, a set of equipment can produce more than 30 formula products.
5. The consumption capacity of extrusion granulation is only electric energy, and there is no emission of three wastes in environmental protection, which conforms to the basic national environmental protection policy and the environmental protection development strategy of Taiwan-funded enterprises.
