A brief description of the double roller extrusion granulator
1. Extrusion granulation 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. Therefore, it can save energy and reduce consumption.
2. There are more than 20 kinds of materials that have been successfully used for extrusion granulation: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, sulfuric acid potassium etc. In addition, the double roller extrusion granulator can flexibly realize the replacement of product formulas in a short time, and a set of equipment can produce products with more than 30 formulas.
3. Because the drying process is omitted, the return ratio is low (about 15% of the total feed volume of the extruder). And the dry granulation does not require additional additives, and it only uses the intermolecular force of the material itself, which not only simplifies the process, but also reduces energy consumption.The investment is low.
There are many types of equipment for granulation, and different equipment plans need to be formulated according to the different materials and capacity. Welcome to contact us for specific information.
