The disc granualtor is a core piece of equipment for the pelletizing of powdery materials in industries such as fertilizer production, metallurgy, and chemicals. It is primarily utilized for processing organic fertilizers and NPK compound fertilizers; thanks to its wide range of applicability and high pelletizing rate, it is a standard model commonly found in large-scale organic fertilizer granulation production lines.
In the field of fertilizer production, it serves as the primary granulation equipment for organic fertilizers, compound fertilizers, and organic-inorganic blended fertilizers. Regarding organic fertilizers, it mainly processes fermented livestock and poultry manure—including chicken, cattle, pig, and sheep manure—as well as other organic waste materials such as straw powder, mushroom residue, distiller's grains, humic acid, biogas residue, and municipal sludge. These materials possess moderate viscosity, and through disc granulation, they can be transformed into smooth, uniform organic fertilizer granules. In the realm of compound fertilizers, the machine primarily processes individual NPK raw materials—such as urea, ammonium chloride, monoammonium phosphate (MAP), diammonium phosphate (DAP), potassium chloride, potassium sulfate, and ordinary superphosphate. By mixing various powdery ingredients and subjecting them to the rolling action of the disc, standard compound fertilizer granules are produced.
Furthermore, the disc granulator is capable of processing raw materials for bio-organic fertilizers and blended fertilizers. It is well-suited to meet the specific granulation requirements of organic-inorganic blended fertilizers and can accommodate the molding specifications of various fertilizer formulations.
Beyond the fertilizer sector, this equipment can also process materials such as metallurgical mineral powders, cement raw meal, refractory materials, coal dust, chemical catalysts, and inorganic salt powders. By adjusting the disc's inclination angle, rotational speed, and water atomization spray, it effectively transforms these powdery materials into spherical pellets through a rolling process.
The equipment has clear requirements regarding input materials, primarily utilizing dry powders that can be successfully molded with the addition of an appropriate amount of moisture; it requires neither high temperatures nor high pressures for operation. This makes it ideal for continuous production processes. It serves as standard granulation equipment for small-to-medium-sized fertilizer plants, organic fertilizer production lines, and compound fertilizer production lines, distinguished by its strong practicality and high versatility.
