The key to the production process of biofertilizer project

The key to the production process of biofertilizer project is the choice of granulation method. According to the production process requirements, the currently used granulation methods of bio-organic fertilizer are mainly disc granulation and tooth-granulation. Due to different requirements of raw materials for different granulation methods, there are differences in the production process of biological organic fertilizer. At present, the production technology of Huaqiang organic fertilizer equipment mainly includes the following.
fertilizer granulator machine
Using the disk granulation production process, the raw materials need to be dried to remove a certain amount of water (when drying, the raw materials are sterilized), and then crushed, and then a certain amount of acid and alkali is added to adjust the pH of the carrier and mixed with the inorganic fertilizer part, and sent The disc fertilizer granulator machine sprays a certain amount of bacteria during the granulation process, and the granulated product is dried and sieved at low temperature to obtain the finished product.

The tooth-granulation granulation process is to use the high-speed rotating mechanical stirring force and the aerodynamic force generated thereby to continuously realize the process of mixing, granulating, spheroidizing and densifying the fine powder in the machine, thereby achieving the purpose of granulation. The shape of the particles is spherical, the sphericity is ≥0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥90%. 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, the rotation speed The higher, the smaller the particles, and vice versa.
