Technology of mixing organic fertilizer granulation machine
After fermentation, the raw material of organic fertilizer is crushed by a semi wet material crusher, screened by a roller screen, and then the coarse material is screened out for fermentation. The fine material can be granulated. The appearance of the particles is more beautiful and the granulation rate is higher.
After fermentation, the material (moisture content is 35%) is mixed by blender, and then it is dried by organic fertilizer granulation mahcine, and then it is cooled by cooler and screened by drum screening machine. The unqualified products are returned to blender. The qualified products can be coated with calcium, magnesium, sulfur and other medium and trace elements by coating machine and powder flapping machine, and then they can be coated by silo and packaging machine.
The process principle of organic fertilizer granulation machine makes use of the high-speed rotary mechanical stirring force and the resulting aerodynamic force to make the fine powder continuously realize the mixing, granulation, spheroidization, densification and other processes in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is ≥ 80%. The size of the particle diameter can be appropriately adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount is, the higher the speed is, and the smaller the particle is.
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.
