As a key piece of equipment for granulating powder materials, the disc granulator, with its compact structure and easy operation, is widely used in various industries, including fertilizers, metallurgy, and building materials.
Structurally, the disc granulator consists of an inclined disc, a transmission mechanism, a frame, and a liquid spraying system. The disc's tilt angle and rotational speed are key parameters influencing granulation efficiency. The angle is typically adjustable between 30° and 50°, while the rotational speed can be flexibly adjusted based on the material's characteristics. During operation, powdered material is fed into the rotating disc. As the disc rotates, the material moves upward along the disc wall under the combined effects of centrifugal force, friction, and gravity. Simultaneously, the liquid spraying system evenly applies a binder, gradually agglomerating the powder into spheres. When the granules reach the desired size, they are discharged from the disc's edge by gravity, completing the granulation process.
In practical application, the disc granulator demonstrates significant advantages. Its high granulation uniformity and moderate granule strength meet the granule specification requirements of various industries. The equipment also offers low energy consumption, enabling continuous production from a single unit, significantly improving the processing efficiency of fertilizer production lines. Furthermore, its strong adaptability to various materials allows for stable operation in applications ranging from the production of organic and compound fertilizers to the molding of metal powders and refractory materials.
With the advancement of industrial technology, disc granulators are constantly being upgraded. The addition of automated control systems enables more precise operation, real-time monitoring of the production process, and further reduces labor costs. As the crucial link between powdered raw materials and finished granules, disc granulators play an irreplaceable role in promoting the intensification and efficiency of industrial production.
