The process flow of a disc granulator production line usually includes the main steps of raw material preparation, granulation, drying, cooling, screening, and packaging. Here is a detailed explanation of this process:
1. Raw material preparation
Raw material crushing and screening: Raw materials (such as fertilizer raw materials, chemical raw materials, etc.) are first crushed to a particle size suitable for granulation by a grinder, and then large particles and impurities are removed by a screening machine to ensure uniform particle size of the raw materials.
Raw material mixing: Mix the crushed raw materials evenly with binders, additives, etc. as needed to improve granulation efficiency and particle quality.
2. Granulation
Disc granulation: The prepared raw materials are fed into a disc granulator, where they gradually form spherical or approximately spherical particles through mutual friction and bonding between the materials under the rotational force of the disc. During this process, the spray system will spray appropriate amount of water or adhesive as required to control the humidity and stability of particles.
3. Drying
Particle drying: After granulation, the particles need to go through a dryer to remove excess moisture, in order to improve the stability and storage of the particles. The drying process requires precise control of temperature and time to avoid particle deformation or adhesion.
4. Cooling
Particle cooling: The dried particles are cooled to room temperature or a suitable temperature by a cooling machine to prevent a decrease in particle quality caused by high temperatures.
5. Screening
Particle screening: Use a screening machine to screen out particles that meet the particle size requirements, remove particles that are too large or too small, and ensure the consistency and quality of the finished particles.
6. Packaging
Finished product packaging: The screened finished product particles are weighed and packaged by an automatic packaging machine, ready for storage or shipment.
7. Control and Monitoring
Automation control: Production lines are usually equipped with PLC control systems to monitor and adjust key parameters in the production process, such as raw material ratio, granulation speed, drying temperature, etc., to ensure the stability of the production process and product quality.
Through the above process flow, the disc granulator production line can efficiently convert powdered or fine-grained materials into uniformly sized and regularly shaped particles, which are suitable for multiple industries such as fertilizers, chemicals, and food, providing convenience for subsequent processing and applications.
