Pan granulator (also as know Disc Pelletizer,or disc granlator), it is a type of fertilizer granulator that is used to produce granules from powdered materials. The disc granulation machines achieve particle aggregation through the cohesive forces of binders or water molecules, combined with the rolling motion of materials within the rotating disc.As the pan rotates, the material is agitated and forms into small round granules. The granules are then dried and screened to achieve the desired size and shape. Pan granulators are commonly used in the production of fertilizers, as well as other industries that require granulation such as pharmaceuticals and food processing.
Application of Disc Granulator Machine
The disc granulator machine, also called disc pelletizer, is used in various industries for making granules from different materials. Its applications include:
Fertilizer Production: It granulates different types of fertilizers, making them easier to handle and improving nutrient release for better crop yield.
Mining and Metallurgy: It agglomerates mineral concentrates, ores, and tailings, making them easier to transport and process.
Chemical Industry: It granulates chemical powders like catalysts and additives, improving their flowability and handling characteristics.
Pharmaceutical and Food Industries: It granulates pharmaceutical powders and food additives, ensuring controlled release and precise dosing.
Chemical Engineering and Research: It helps scientists and engineers study and optimize the granulation process for different materials in laboratories.
Typical Application Cases
• Agricultural field: In the production line of NPK compound fertilizer with an annual output of 100,000 tons, disc granulator has become the mainstream choice due to low energy consumption and good particle uniformity;
• Environmental protection field: When municipal sludge is pelletized for treatment, the advantage of adhesion of disc pelletizer is utilized to make sludge into fuel pellets;
• Chemical industry: Calcium carbonate, magnesium carbonate and other powders are granulated to improve product fluidity and transportation safety through disc rolling molding.
Core Advantages of the Disc Granulator
1. Strong process adaptability and wide compatibility of raw materials
• Applicable material type:
It can handle organic fertilizer, inorganic fertilizer (such as NPK compound fertilizer), chemical raw materials, metallurgical powder and other granular or powdery materials, especially suitable for the system containing viscous components (such as clay, humus) or the need to add binder (such as water, syrup, molten material).
• Raw material moisture tolerance:
Requirements for the moisture content of raw materials are relatively loose (usually allowed 5% ~ 20% humidity), and in some cases, it can directly process wet materials, reducing the pre-treatment process.
2. Particle characteristics can be controlled, stable quality of finished products
• Flexible adjustment of particle size and shape:
◦ By adjusting the inclination angle of the disk (usually 30°~60°), rotational speed (10~30rpm) and material residence time, particles of 2~10mm particle size can be produced, and the particles have a high degree of sphericity (close to ellipsoid) and a smooth surface.
◦ Example: the higher the inclination angle and the higher the rotational speed, the smaller the particle size; conversely, the larger the particle size.
• Adjustable particle strength:
Depending on the amount of binder and rolling compaction, the hardness of the granules can be controlled and adapted to different transportation and application scenarios (e.g., mechanized seeding requires high granule drop strength).
3. The equipment structure is simple, low maintenance costs
• Mechanical construction advantages:
Mainly consists of disc, drive device, bracket, no complex transmission parts (such as churn, mold), equipment failure rate is low, routine maintenance only need to check the bearing lubrication and disc wear.
• Easy replacement of wear parts:
The surface of the disc can be coated with wear-resistant coatings (e.g. ceramic, polyurethane), and the cost of replacement after wear and tear is much lower than that of the roll-press assembly of an extruder pelletizer.
How to choose pan granulator machine?
Small disc granulator:
Small disc granulators are commonly used for small-scale fertilizer production or for laboratory research. They are compact and easy to operate, making them suitable for use in small spaces or by inexperienced operators.
Medium disk granulator:
A medium disk granulator is a type of equipment used for producing fertilizer pellets. It is similar to a small disk granulator, but with a larger size and higher production capacity. Medium disk granulators are commonly used in medium-sized fertilizer production plants.
Large pan granulator:
A large disc granulator is a type of equipment used for producing fertilizer pellets on an industrial scale. It is similar to a medium or small disc granulator, but with a much larger size and higher production capacity. Large disc granulators are commonly used in large-scale fertilizer production plants.
New Organic Fertilizer Pan Granulator: A new organic fertilizer disc granulator is a type of equipment used for producing organic fertilizer pellets. It is an updated version of the traditional disc granulator and is designed specifically for producing organic fertilizer pellets.
