Application of drum granulator in complete organic fertilizer production line


The complete production line of drum stirring and toothed granulation combines various advantages for particle processing of organic raw materials after fermentation. Before granulation, the fermented raw materials are crushed, and the ingredients are directly mixed with a mixer into the granulation machine to produce spherical particles. The particles produced by this machine are spherical, with an organic content of up to 100%, greatly saving energy and improving utilization efficiency. The direct goal of the customer has been achieved by directly processing pure organic matter into particles, and utilizing the characteristic of organic fertilizer raw materials being embedded and enlarged under certain conditions. No additives, adhesives, etc. need to be added during granulation. After the finished product is produced, the particle strength is very good. After granulation, it is directly screened to reduce drying energy consumption and save coal electricity.

The stirring teeth granulator is suitable for pelletizing organic fermented fertilizers for urban household waste, including organic fertilizer raw materials such as animal manure, compost, green manure, sea manure, cake fertilizer, peat, soil and miscellaneous fertilizers, three wastes, microorganisms, etc. The particles are irregular spherical particles. The qualified granulation rate of this machine is over 90%, suitable for various formulas. The compressive strength of organic fertilizer is higher than that of discs and drums, and the large ball rate is less than 15%. The particle size uniformity can be adjusted according to user requirements through the machine's stepless speed regulation function. This machine is suitable for direct granulation of organic fertilizer after fermentation, saving drying processes and greatly reducing manufacturing costs. The main body of the granulator is lined with stainless steel plates to prevent the material from sticking to the wall, resulting in high particle smoothness and beautiful appearance.

The complete set of organic fertilizer production line with drum stirring teeth utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thereby achieving the purpose of granulation. The particle shape is spherical, with a sphericity of 0.7 and a particle size generally between 0.3-3 millimeters. The particle formation rate is 98%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, the smaller the particle, the lower the rotation speed, and the larger the particle.
