In the process of organic fertilizer production, powder materials are transported to disc granulator by belt conveyor. The inclination angle is 50 ° The turntable rotates with the material. Like rotary drum granulators, disc granulators use wet granulation to shape particles.
When the material reaches a certain height, its gravity and inertia separate from the disc, slide along the bending path, and complete the rolling required by granulation under the action of force.
At the same time, the liquid sprayed by the spraying system is evenly sprayed on the rolled material to condense into particles, so as to complete the whole granulation process.
Dry granulation is a low-cost fertilizer processing technology, not wet manufacturing. In the manufacture of NPK fertilizer, the dry powder particles are directly rolled into the other one, leading to the formation of chemicals.
How to make npk granules?
This method is used in the environment that requires humidity and temperature control granulation, so it can not only produce NPK fertilizer, but also granulation in this way. Dry manufacturing is a kind of powder fusion method, which is used in pharmaceutical industry and chemical fertilizer process to improve the fluidity of powder by increasing particle size.
The roller granulator provides a powerful dry manufacturing process to produce particles with excellent fluidity. It is found that the fertilizer prepared by this method has good uniformity, compactness and low brittleness. The use of this method helps to reduce the physical and chemical limitations used to overcome materials.
