Ingenious Working Principle
The disc granulator utilizes the rotational movement of an inclined disc to make materials undergo rolling motion under the combined action of centrifugal force, gravity, and friction. With appropriate liquid phase participation, powdered materials gradually form uniform granules through agglomeration. The disc's inclination angle, rotation speed, and edge height can all be precisely adjusted according to process requirements to ensure ideal granule size and strength.
"The charm of disc granulation lies in the visibility and controllability of its process," says a senior process engineer. "Operators can directly observe the granulation process and promptly adjust process parameters."
Complete Production System
In NPK fertilizer production lines, the disc granulator works together with other fertilizer equipment to form a complete production system:
Raw Material Section: Includes chain crusher,rotary screener machine, and batching system to ensure precise raw material particle size and proportioning.
Granulation Section: The disc granulator serves as the core, working with liquid phase spraying systems to complete the granulation process.
Drying and Cooling Section: Rotary dryers and coolers are responsible for adjusting granule temperature and humidity.
Screening and Coating Section: Vibrating screens perform particle size classification, while coating machines enhance product performance.
Significant Technical Advantages
The widespread application of disc granulators in NPK fertilizer production mainly benefits from the following advantages:
High Pelletizing Rate: Typically reaching 80-90%
Uniform Particle Size: Good sphericity, concentrated particle size distribution
Flexible Operation: Convenient adjustment of process parameters
Lower Energy Consumption: More energy-efficient compared to other granulation methods
Easy Maintenance: Simple structure, reliable operation
A production supervisor from a large fertilizer plant shares: "After adopting disc granulation technology, product quality has significantly improved, and market competitiveness has noticeably strengthened."
Continuous Technological Innovation
With the development of automation technology, modern disc granulators have achieved intelligent upgrades. PLC control systems can precisely control disc rotation speed, inclination angle, and liquid phase addition, ensuring stable production processes. Online monitoring systems collect data in real time, providing basis for process optimization.
Globally, disc granulation technology continues to support agricultural production. From basic fertilizers to specialized formula fertilizers, from large-scale production to customized processing, this technology plays an important role.
The successful application of disc granulation technology reflects the perfect combination of simple principles and precision manufacturing. In the most direct way, it achieves the most efficient fertilizer production, providing reliable support for the development of modern agriculture.
