What is Disc Granulator?

Disc granulator is an important equipment for converting powdered materials into uniform round granules. The disc granulator is composed of an inclined granulating disc, a driving device, a disc inclination adjusting mechanism, a frame, a charging sprayer, a scraper and other components.

Features of Disc Granulator

Diameter: 0.8– 4.5m (2.625′ – 14.764′ )

Capacity: 0.5 TPH – 15 TPH

Uniform finished granules and good automatic classification ability.

High granulation efficiency and low return ratio.

Visual and simple operation, easy to control, flexible formula.

The disc angle can be easily adjusted.

A variety of materials are available, stainless steel optional.

Applications of Disc Granulator 

A Disc Granulator, also known as a Disk Pelletizer, is a piece of equipment commonly used in the production of granules (or pellets) by agglomerating powder materials. This granulation process is widely applied in various industries. Below are some key applications of Disc Granulators:

1. Fertilizer Production
Application: Disc Granulators are extensively used in the production of both organic and inorganic fertilizers. In this case, raw materials (such as ammonium nitrate, urea, and phosphate) are mixed, and the disc granulator forms the mixture into uniform pellets.
Benefit: The process helps in creating granules that have uniform size, are easy to handle, and have improved solubility for efficient nutrient release in soils.
2. Pharmaceutical Industry
Application: In pharmaceuticals, Disc Granulators are used to produce granules for tablets and capsules. Active pharmaceutical ingredients (APIs) and excipients are mixed and processed into granules that facilitate uniform blending, compressibility, and consistency in dosage.
Benefit: Granulating drugs ensures uniformity in drug composition and controlled release of active ingredients.
3. Animal Feed Production
Application: Disc Granulators are used to pelletize animal feed ingredients, creating uniform-sized feed pellets for poultry, cattle, and other livestock. The ingredients, such as grains, vitamins, and minerals, are agglomerated into granules.
Benefit: Pellets are easier for animals to consume, and granulation helps in better feed conversion ratios and reduces waste.
4. Chemical Industry
Application: In the chemical industry, Disc Granulators are used to process materials like catalysts, pigments, and dyes into granules. These granules help improve handling, storage, and application properties of chemicals.
Benefit: Granulation improves flowability, reduces dust, and provides a controlled release of chemicals in various applications.
5. Recycling and Waste Treatment
Application: Disc Granulators are used to recycle materials and form waste into usable pellets. For example, in the recycling of plastics, rubber, and other waste products, the granulator helps in converting the material into smaller, more manageable pellets for further use.
Benefit: The process helps reduce waste volume and makes it easier to handle or transport the material for reuse.
6. Ceramic Industry
Application: In ceramics, Disc Granulators are used to make ceramic powders and materials into pellets. This process ensures uniform size and density, which are crucial for achieving consistent results during firing.
Benefit: Granulation ensures high-quality ceramic production, improves sintering uniformity, and reduces the likelihood of defects in the final product.
7. Mining and Metallurgy
Application: Disc Granulators are used in the mining industry for agglomerating materials like ores or minerals. For example, iron ore pellets are made using a disc granulator, which are then used in the blast furnace for steel production.
Benefit: Pellets have better flow properties, more uniform size, and greater surface area, which enhances the efficiency of subsequent processing steps like sintering or reduction.
8. Food Industry
Application: Granulation in the food industry is used to form ingredients like sugar, salt, spices, and powdered additives into pellets for easier handling, storage, and consistent application in food products.
Benefit: Granulation ensures even distribution and better consistency in food products.
9. Cement Industry
Application: In cement manufacturing, a Disc Granulator is used to form raw materials, such as limestone and clay, into pellets that are easier to transport and mix. These pellets are then used in kilns for cement production.
Benefit: The uniformity of granules helps improve the quality of the final cement product.
10. Agricultural Products (Seeds & Plant Nutrients)
Application: Granulators can also be used for producing granular seeds, micronutrient fertilizers, and other agricultural products. The pellets are uniform and easy to apply to fields.
Benefit: Granules facilitate controlled release and even distribution, improving crop yields and overall soil health.
