Characteristics and working principle of roller granulator
More and more enterprises will choose to use roller granulator, which is produced by non drying and normal temperature process. The equipment has the advantages of less investment, quick effect and good economic benefit. The complete set of equipment has compact process layout, scientific and reasonable, advanced technology, energy saving and consumption reduction, no three wastes discharge, stable operation, reliable operation and convenient maintenance.
The advantages of the roller granulator are as follows
1) Compared with other methods, granulator machine for fertilizer does not need fuel oil, gas and other drying measures.
2) There is no need to add additional binder to the granulator machine for fertilizer. Steam granulation is a common production method for compound fertilizer in China. After condensation and crystallization between the material molecules, the steam acts as an adhesive in the process of making. However, during the drying process, the water inside and on the surface of the granule must be driven out, otherwise the fertilizer is easy to stick and agglomerate in the storage process, Only the intermolecular force of the material itself is used to simplify the process and reduce the energy consumption.
3) The investment of the fertilizer granulator machine is low, because the drying process is omitted, and the return ratio is low (accounting for about 15% of the total feed amount of the extruder), the process is simple and the investment is low.
4) At present, there are more than 20 kinds of materials successfully used in extrusion granulation: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc.
