Price advantage of roller granulator:
1. Energy saving roller granulator
is used for granulating materials under normal humidity. Compared with other methods, it does not need fuel oil, gas and other drying measures.
2. There is no need to add additional binder. The common production method of compound fertilizer in China is steam granulation of drum granulator
. Water vapor condenses and crystallizes between the material molecules and acts as an adhesive in the granulation process. But in the drying process, the water inside and on the surface of the particles must be driven out, otherwise the fertilizer is easy to stick and agglomerate in the storage process. However, dry granulation does not need additional additives, and only uses the intermolecular force of the material itself, which simplifies the process and reduces 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 urea, calcium nitrate, potassium sulfate and so on. In addition, the roller granulation process can flexibly change the product formula in a very short time. A set of device can produce more than 30 kinds of products.
5. Green environmental protection has no three wastes discharge. The ability of roller granulator consumption is only electric power, and environmental protection has no three wastes discharge. It adapts to the basic national policy of environmental protection and conforms to the development of environmental protection of enterprises.
