Working principle and application scope of new rotary drum granulator for organic fertilizer
The new rotary drum granulator is widely used in the granulation of organic and inorganic fertilizers. Due to more granulation rate, stable operation, strong and durable equipment, long service life, it is selected as the ideal product by the majority of users. Our company has developed and produced more than 600, 800, 1000, 1200 and 1500 kinds of internal and external rotary granulators. We can also develop and produce other specifications of internal and external rotary granulators according to the requirements of users. The shell of granulator is made of thickened seamless steel pipe, which is durable and never deformed. In addition, the stable base design makes its operation more stable.
The working principle uses the high-speed rotary mechanical stirring force and the resulting aerodynamic force to make the fine powder continuously realize the mixing, granulation, spheroidization, extrusion, collision, densification, polishing and other processes in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, fertilizer granulator machine price concessions, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3mm, 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 is, the higher the speed is, and the smaller the particle is. Scope of application: This organic fertilizer granulator machine is especially suitable for the granulation of light fine powder materials, especially for the granulation of organic-inorganic compound fertilizer. The finer the basic particles, the higher the sphericity and the better the quality of the pellets.
It is generally required that the particle size of materials before granulation should be less than 50 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, nitrogen, phosphorus, potassium and other organic-inorganic compound fertilizers are suitable. The granulator developed and produced by our company is based on the manufacturing principle and technology of stirring granulator and drum granulator (npk fertilizer granulator). It is elaborately developed and repeatedly tested. It can be produced at normal temperature to ensure the quality of products With reasonable structure design, it can produce spherical granular products with low water content, easy drying, high molding rate, good particle strength and beautiful appearance. It is an ideal granulation equipment for biological organic fertilizer, organic-inorganic fertilizer and organic-inorganic compound fertilizer. The application scope of the new type agitator granulator: peat, sludge, chicken manure, livestock manure, lignite, filter sludge from sugar factory, paper-making sludge, liquor, straw, soybean residue, peat and other organic wastes can be directly granulated after fermentation treatment, which completely solves the key technical problems of traditional disc (drum) granulation process, such as fermentation, etc.
