The role of the roller squeeze granulator is to squeeze out the air between the particles, and to make the distance between the particles close enough to generate attractive forces such as van der Waals force, adsorption force, crystal bridges and embedded connections. The granulation of extrusion granulation is mainly based on the strength of the granule formed by the force between the molecules. The following content is the detailed information of roller extursion granulator with price advantages.
- The dry extursion granules making machine applies the design of energy-saving and consumption-reducing extrusion granulation. This means that the material is granulated at room temperature. Compared with other methods, it does not require drying measures such as fuel oil and gas.
- There is no need to add additional binders. The commonly used domestic compound fertilizer production method is steam granulation. After the water vapor condenses and crystallizes between the material molecules, it acts as a binder in the manufacturing process. However, 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 during storage. Using the double roller pelletizer with dry granulation does not need additional additives, only uses the intermolecular force of the material itself, which simplifies the process and reduces energy consumption.

Double roller granulator is suitable for pelleting with dry granulation craft. - Lower investment. Because the drying process is omitted, and the return ratio is low (accounting for about 15 of the total feed volume of the extruder), the process flow is simple and the investment is lower.
- Raw material composition Flexible extrusion granulation production line of raw materials is wide. Currently, more than 20 kinds of urea, ammonium chloride, calcium nitrate, potassium sulfate, etc. have been successfully used for extrusion granulation. In addition, the extrusion granulation process can flexibly realize the replacement of product formulas in a very short time, and a set of equipment can produce products with more than 30 formulas.
- When using the double roller extrusion pelletizer, green environmental protection has no emissions of three wastes, and the capacity of extrusion granulation consumption is only electric power, and environmental protection has no emissions of three wastes. It adapts to the country’s basic national policy on environmental protection and is also in line with the development strategy of enterprise environmental protection.
