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.

When using the الحبيبات بثق الأسطوانة to make bio NPK fertilizer granules, the following is the complete process: أولاً, the belt conveyor transports the bio NPK raw material (N, ص, K, little bio compost ect. )to the roller extruder. ثانيًا, 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.

The maximum output of the double roller press granulator is 2t. لذلك, 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. على سبيل المثال, عندما تريد الإنتاج 6 طن من الثبات الحيوي في الساعة, Yushunxin can configure 4 roller extrusion granulators with an output of 1.5 tons per hour for you. If you have other output requirements, الرجاء الاتصال بنا!

The hardness of biological NPK fertilizer pellets produced using a double-roller granulator is generally 15-20N. If the hardness of the granules is not enough, you can adjust the compression force of the granulation machine, or use a suitable adhesive.

Long-term use of the roller press granulator will cause wear of the granulation roller skin. YUSHUNXIN's double rollers are made of 20GrMoTi and can be used for about half a year. We can also provide you with spare parts. بالطبع, you can also buy them locally.
