The double roller granulator is a high-quality biological fertilizer granulation equipment. It uses dry granulation technology to quickly make chemical powder into granules through double roller extrusion. Due to its corrosion resistance and low investment, it is favored by many bio NPK fertilizer manufacturers.
What is the pelletizing process of double roller pressing granulator?
When using the roller extrusion granulator to make bio NPK fertilizer granules, the following is the complete process: First, the belt conveyor transports the bio NPK raw material (N, P, K, little bio compost ect. )to the roller extruder. Secondly, the raw material will pass through two counter-rotating granulation roller sheet. These shafts have specific molds and ball sockets, and under the action of extrusion, a uniform size of bio NPK fertilizer is formed.
Methods for adjusting bio NPK fertilizer granules with double roller granulator:
The final size of the NPK bio fertilizer granules produced by the double roller extrusion granulator is between 3-10mm. It is related to the shape of the ball sockets on the two rollers. You can choose a roller with a ball socket of the required size. In addition, adjusting the distance between the two rollers is also a method. The smaller the roller spacing, the larger the size of the NPK bio fertilizer pellets. So, by adjusting these two roller, you will produce different size of bio compound fertilizer granules.
How much capacity can I setup a NPK biofertilizer plant using a double-roller extrusion granulator?
The maximum output of the double roller press granulator is 2t. Therefore, you can use it to set up the small scale compound biofertilizer production line. But don’t worry. It is also suitable for large scale NPK bio fertilizer manufacturing plant. You only need to buy a few more for your roller extrusion granulator production line. For example, when you want to produce 6 tons of bio-fertilizer per hour, YUSHUNXIN can configure 4 roller extrusion granulators with an output of 1.5 tons per hour for you. If you have other output requirements, please contact us!
