The granulation technology of drum granulator in organic fertilizer production line

 The working principle of the rotary drum stirring tooth combined granulator uses the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously realize the mixing of the fine powder in the machine, granulation, spheroidization, extrusion, collision, and densification, polishing and other processes, so as to achieve the purpose of granulation. The shape of the particles produced by this organic fertilizer granulator machine 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 mixing amount of the material and the spindle speed. , Generally, the lower the mixing amount, the higher the speed and the smaller the particles.

 

The new rotary drum stirring tooth combined granulator produces bacteria at room temperature and has a reasonable structure design. It can produce spherical type granular products. The produced granules have low water content, easy drying, high forming rate, good granule strength, and beautiful appearance. It is the ideal granulating equipment for bio-organic fertilizer, organic-inorganic fertilizer, organic fertilizer and inorganic compound fertilizer.
The scope of application of the new type combined stirring tooth drum granulator: After fermentation treatment of organic waste such as peat, sludge, chicken manure, livestock manure, lignite, sugar factory filter sludge, paper sludge, wine, straw, bean dregs, grass charcoal, etc. It can be directly granulated, which completely solves the key technical problems that are difficult to solve by the traditional disc (rotating drum) granulation process, fermentation, etc., and granulates the raw material of bio-organic fertilizer.
