What is a disc granulator

The disc granulator is a type of granulator that has the advantages of uniform granulation, high granulation rate, smooth operation, sturdy and durable equipment, and long service life. Usually composed of discs, scrapers, screens, transmission devices, feeding devices, discharging devices, and control systems. Among them, the disc is the core component, which can adjust the tilt angle and speed as needed.

How Does This Machine Turn Powder into Spheres?

A disc granulator works by tumbling fine powder in a rotating, angled pan while spraying a fine mist of liquid. This causes the powder to stick together and grow layer by layer, just like rolling a snowball.

The principle is elegantly simple and very effective. We designed our disc granulator to perfect this natural process for industrial production.

• Feeding the Powder: First, your finely powdered raw material, which has been processed by a crusher and mixer, is continuously fed into the rotating pan.
• Rotation and Tumbling: The pan rotates at a specific speed and is set at a precise angle. As the pan turns, the powder tumbles inside.
• Adding Liquid: A spray system mists a small amount of water or a liquid binder onto the tumbling powder. This makes the fine particles slightly sticky, causing them to cling together and form tiny “cores” or seeds.
• The Snowball Effect: These small cores continue to roll and tumble inside the pan. As they roll, they pick up more and more powder, growing in even layers. This is a continuous process.
• Discharge: As the granules grow larger and heavier, they naturally move to the outer, lower edge of the pan. Once they reach the desired size, they spill over the rim and are collected as the finished product.

Characteristics of fertilizer granulation process

The disc granulator can ensure that the raw materials are evenly distributed on the disc, thereby forming uniform particles. Due to the unique design and working principle of the disc granulator, its granulation rate is usually high, reaching over 70-90%. The disc granulator is suitable for various powdered or granular raw materials, including fertilizers, pesticides, feed, pharmaceuticals, chemical products, etc.

How Do You Control the Granule Size and Quality?

You have complete control over the final granule size. This is achieved by adjusting three key parameters on the machine: the angle of the disc, its rotation speed, and the amount of liquid you spray.

This level of control allows you to fine-tune the process to create exactly the product you want.

• Disc Angle Adjustment: Our granulators are built on a robust frame that allows you to easily change the tilt angle of the pan. A steeper angle (e.g., 55 degrees) makes the granules roll out faster, resulting in smaller granules. A flatter angle (e.g., 40 degrees) keeps the material in the pan longer, allowing it to grow larger.
• Rotation Speed: The machine is equipped with a high-quality motor and transmission that provides a stable rotation speed. Adjusting this speed controls the forces inside the pan, affecting the density and formation of the granules.
• Precise Liquid Spray: The amount of water is critical. We use an adjustable spray system with fine nozzles. This allows your operator to add just the right amount of moisture to facilitate granulation without turning the powder into mud.

This combination of controls makes the disc granulator a highly intuitive and flexible machine for any skilled operator.

What Are the Main Business Advantages?

The key advantages are an extremely high granulation rate, superior granule quality, and simple, reliable operation. This means you waste less material, create a more valuable product, and experience less downtime.

Choosing a disc granulator for your fertilizer plant is an investment in quality and efficiency.

• Extremely High Granulation Rate: Our machines are designed to achieve a granulation rate of over 93%. This means that 93% of the powder that goes in comes out as correctly sized granules in the first pass. The small amount of un-granulated powder is easily screened out and recycled back into the pan. This high efficiency saves energy and maximizes your output.
• Superior Granule Quality: The gentle “snowballing” process produces granules that are remarkably uniform in size, round in shape, and have a smooth surface. These high-quality spheres are stronger, produce less dust, are easier to store without caking, and flow freely through application equipment. A better-looking product can often sell for a higher price.
• Simple and Reliable Operation: The machine’s structure is very straightforward. There are no complex internal parts like blades or press rollers. The main components are the disc, the motor, and the frame. This simple design makes it incredibly durable, with very few wear parts to replace. It is easy to operate and requires minimal maintenance.

The disc granulator is widely used, covering multiple industries such as chemical industry (such as fertilizers and pesticides), pharmaceuticals (such as capsules and tablets), food (such as saccharin and monosodium glutamate), building materials, rubber, feed, etc. It is suitable for processing various non viscous materials such as powders and small pieces, and can efficiently convert these materials into uniform granular products, meeting the needs of various industries for granular products.

Is a Disc Granulator the Right Choice for You?

A disc granulator is the perfect choice if your goal is to produce a high-quality, round, uniform granular product. It is extremely versatile and works well for both organic and compound fertilizer production.

This machine is one of the most popular choices for a wide range of granulation needs. It is particularly well-suited for these businesses:

• Organic Fertilizer Producers: It is excellent for granulating finely powdered organic materials like composted livestock manure, agricultural waste, and municipal sludge. The process effectively turns low-value powder into a high-value granular product.
• Compound Fertilizer Manufacturers: For producing NPK or other compound fertilizers, the disc granulator creates a premium, homogenous granule. The tumbling action thoroughly combines the different nutrient powders into each sphere.
• Other Industries: This technology is also widely used in the chemical, cement, and mining industries to turn fine powders into easy-to-handle pellets.

Frequently Asked Questions (FAQ)

• Question 1: What is the ideal moisture content for the powder?
• The raw material powder should be mixed with water to reach a moisture content of about 25% to 30%. This is the optimal range for the “snowballing” effect to work efficiently.
• Question 2: Does this machine need to work with a dryer?
• Yes. Because this is a wet granulation process, the granules coming out of the machine will be damp. They must be sent to a rotary dryer and then a cooler to remove the excess moisture and harden them for storage and packaging. These are all parts of our complete fertilizer production lines ³.
• Question 3: What is the main maintenance for a disc granulator?
• The machine requires very little maintenance. The primary tasks are regular lubrication of the motor and gear parts, and keeping the scraper clean. The pan itself is very durable and does not have parts like blades or screens that need frequent replacement.
• Question 4: What is the difference between a disc granulator and a new type organic fertilizer granulator?
• A disc granulator creates granules by tumbling. A new type organic fertilizer granulator ^4 1 1 uses high-speed stirring and the friction between particles to form granules. Both are excellent wet granulation methods, but the disc granulator typically produces rounder and more uniform spheres.

Organic fertilizer production line process

The organic fertilizer production line is a production system that integrates the steps of raw material collection, pretreatment, fermentation, granulation, drying, screening, packaging, etc. It can convert organic waste such as aquaculture waste, crop straw, and food processing waste into organic fertilizers rich in nutrients for agricultural production.

The disc granulator is the undisputed champion for manufacturers who want to produce a premium fertilizer with a uniform, round shape. Its simple design, reliable performance, and incredibly high granulation rate make it a smart and profitable investment. By giving you precise control over the final product, it allows you to meet the highest market standards. Whether you are processing organic compost or creating a specialized compound fertilizer, this machine provides an efficient and effective path to a superior granular product.
