Drum granulation technology of NPK fertilizer granulator
The production line process of drum granulator includes raw material batching machine, fertilizer mixer machine, crusher, drum granulator, particle dryer, particle cooler, coating machine for finished product, and quantitative packaging machine for finished product.
The rotary drum granulator is an inclined cylinder in the granulation device, which is like the overlapping of multiple discs, so the granulation efficiency is high. In addition, steam can be used in the reactor, and the granulation efficiency is high due to the small viscosity of the materials or the water vapor filling. The formula limit is relatively small. Can also be used through the pipe part of the spray, part of the ammoniation.
For the most equipment type, 2-3 million can be used as one line, with a daily output of 280-400 tons, and a good formula can reach more than 500.
The ratio of the above two kinds of nitrogen fertilizer should not be too high. If the nitrogen is higher than 22 and the concentration is higher than 40, it is difficult to do it, because the material reflects the effluent and the drying conditions are difficult to reach the standard at the same time.
The fertilizer granulators produced by Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. include organic fertilizer granulator, disc granulator, drum granulator, npk fertilizer granulator, double roller granulator, two in one organic fertilizer granulator, drum granulator, flat die pelleting machine, and ring die pelleting machine.
