The working principle and structural features of the disc granulator

Disc Granulator It is a new type of inclined-disc granulation device: the granulation rate can reach 95 More than %. The reducer and motor are driven by a flexible belt, which ensures smooth startup, reduces the impact force on the buffer, and enhances the equipment's performance. ​​ The service life is enhanced. The bottom of the disc is reinforced with multiple radiating steel plates, making it robust and durable—resistant to deformation, thickening, and weight gain—and featuring a sturdy base design. It operates stably without requiring anchor bolts. The main gear of the pelletizer undergoes high-frequency quenching, significantly extending its lifespan. Additionally, the anti-corrosion treatment applied inside the pelletizing disc ensures long-lasting durability. This machine delivers uniform pelletizing, boasts a high balling rate, operates smoothly and reliably, and is built to last. Henan Yuguang Metallurgical Disc Granulator It has a long service life and is highly praised by users.

Work Principles

Disc Granulator How it works: The main motor drives the pulley and belt, while the pinion gear is powered by the reducer. The small pinion gear, fixed at the bottom of the disc, meshes with a larger gear to apply force onto the material. The design of the large gear has been specially optimized for efficiency. It’s mounted on a spindle secured to the machine frame’s adjustment plate, providing stable support for the entire granulation plate during operation (this machine is used in conjunction with a spraying device). Once the material enters the granulation plate, it continuously rotates and is evenly sprayed across the surface, enabling the particles to adhere uniformly and form spherical granules. Additionally, the upper section of the machine features an automatic material-cleaning mechanism that prevents物料 from sticking to the walls, significantly extending the machine’s lifespan. Thanks to the continuous rotation of the electric motor and the steady flow of material, the machine can achieve mass production while seamlessly meeting the demands of uninterrupted operation.

Structural Features

Disc Granulator It can be divided into five parts:

Rack Section: Since the entire mechanism—including both the transmission components and the rotating working parts—is supported by the rack, the forces involved are substantial. Therefore, the machine’s rack section is fabricated from high-quality carbon channel steel welded together, ensuring it meets rigorous quality certifications and specialized technical requirements to perfectly fulfill the machine’s intended purpose.

Adjustments section: Disc Granulator At the heart of the system is the granulation disc, whose entire central area is housed within the installation and adjustment section. Our company specializes in using high-quality carbon steel plates and channel steel, meticulously welded together—and all products have successfully passed rigorous quality certifications, fully meeting the machine's requirements.

Transmission section: Disc Granulator The transmission system is crucial, enabling the overall operation to achieve this. Both the motor and the reducer, which are mounted on the gearbox adjustment frame, have been purchased. ISO / 9001 Quality system-certified products, delivering reliable performance. Motor-driven pulleys and belts are used, along with a gearbox and pinion gear. The large gear on the granulation disc is driven by the pinion gear, enabling the disc to operate smoothly. Additionally, both the large and small gears undergo high-frequency quenching, significantly extending their service life—up to twice as long as before. The disc is securely mounted on the drive shaft of the adjustment plate, while the connecting portion at the column head features a tapered fit, ensuring a more rational and efficient design.

Granulation disc section: Disc Granulator The granulation disc features an integrated arc-shaped design, enabling a granulation rate of up to 92 More than %. The bottom of the granulation pan is also reinforced with multiple radiation steel plates, making it sturdy, durable, and resistant to deformation.

Automatic material-cleaning component: This part is installed above the granulation tray, forming a lower-frame structure, with an automatic material-cleaning plate mounted on top for easy removal of materials adhering to the tray walls during cleaning. During production, this significantly extends the machine's service life while reducing labor costs.
