What is a compound fertilizer granulator

The use of the new type of compound fertilizer granulator is a new type of machinery for producing granular organic fertilizers. It utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to achieve continuous mixing, granulation, spheroidization, extrusion, collision and densification of fine powder materials in the machine, thereby achieving the goal of granulation.

How Does It Handle High-Moisture Materials?

This machine excels with wet materials because its powerful stirring action is too fast and forceful for the material to stick to the machine’s inner walls. It can handle moisture content from 25% to 40% without clogging.

This is a game-changer for organic fertilizer producers. Normally, after the composting stage using a compost turner ², the material has a high moisture content. With other granulation methods, you would need to send this material to a large, energy-intensive dryer first just to prepare it for granulation. This machine lets you skip that entire step.

This powerful design gives you two huge advantages:

• Massive Energy Savings: Rotary dryers are one of the most expensive pieces of equipment to run in a fertilizer plant. By granulating wet material directly, you eliminate the need for pre-drying. This dramatically lowers your fuel or electricity costs.
• Simplified Production Line: Your entire factory layout becomes simpler and requires a smaller footprint. You save money not only on the dryer itself but also on the conveyors and space needed to connect it. Your initial investment in a complete fertilizer production line can be significantly lower.

What are the components of the fertilizer granulator system

1. Feeding system: responsible for feeding various fertilizer raw materials into the equipment.
2. Mixing system: Uniformly mix multiple fertilizer raw materials to ensure consistent proportions of various nutrients in each particle.
3. Granulation system: Using mechanical pressure or other principles, the uniformly mixed materials are processed into granules. The granulation process may involve multiple steps such as crushing, grinding, stirring, and pressure granulation.

The advantages and characteristics of fertilizer granulation process

Biological fertilizer granulator

The compound fertilizer granulator can achieve fully automated production from raw material feeding, mixing, granulation to packaging, greatly improving production efficiency. In the manufacturing process of equipment, emphasis is placed on energy conservation and consumption reduction. By optimizing the process flow and adopting high-efficiency energy-saving equipment, energy consumption in the production process is reduced. It can also ensure that the proportion of various nutrients in each particle is consistent, and the particle size is uniform and the surface is smooth, which is conducive to the dissolution of fertilizers and the absorption and utilization of crops.

What Are the Key Benefits for Your Farm or Plant?

The main benefits are lower energy costs, a more reliable process for organic waste, and the production of strong, almost polished granules. It simplifies your operation and improves your final product.

Investing in this specialized granulator offers direct, practical advantages for any business turning organic waste into valuable fertilizer.

• Save Money on Energy: As explained, skipping the pre-drying step is the single biggest advantage. For a medium-sized plant, this can save thousands of dollars per month in operational costs.
• Turn “Problem” Waste into Profit: This machine was born to handle the tough stuff. Sticky chicken manure, fibrous mushroom compost, or stringy municipal sludge that would jam other machines can be processed efficiently. It makes granulation possible for a wider range of raw materials.
• High Granulation Success Rate: The powerful mechanical force ensures a very high percentage of the material is turned into granules, often over 90% on the first pass. This means less material needs to be recycled, making the whole process more efficient.
• Produces High-Quality Granules: The intense, high-speed process creates very dense granules that are hard and resistant to crushing. The constant rubbing action also gives the granules a naturally smooth and rounded finish, making them look more appealing.

Is This Machine the Right Choice for Your Material?

This machine is the BEST choice if your primary business is granulating 100% pure, high-moisture organic materials. It is the specialist for converting farm and municipal waste into high-value fertilizer.

This granulator is a specialist tool. It is not an all-purpose machine. We highly recommend it for:

• Livestock and Poultry Farms: Perfect for granulating composted chicken manure, pig manure, cow dung, and sheep manure. These materials are often wet and have excellent natural binding properties.
• Large-Scale Composters: If you process green waste, food waste, or other compostable materials, this machine can turn your finished compost into a marketable granular product.
• Mushroom Production Bases: Spent mushroom substrate is a fantastic organic material but can be fibrous. This machine can handle it effectively after it has been properly prepared with a semi-wet material crusher⁴.
• Municipal Sludge Treatment: It can granulate dewatered and composted sewage sludge, turning a city’s waste problem into a valuable soil conditioner.

Frequently Asked Questions (FAQ)

• Question 1: Do I still need a dryer after this granulator?
• Yes. Although you skip pre-drying, the granules exit the machine with the same high moisture content they started with (25-40%). You must still pass them through a dryer and cooler to reduce the moisture to a stable level (below 12%) for bagging and storage.
• Question 2: What is the maintenance like?
• Maintenance is straightforward. The main wear parts are the internal stirring teeth. They are made from a highly wear-resistant alloy and are designed to be easily and quickly replaced when they eventually wear down. Routine checks and bearing lubrication are the other key tasks.
• Question 3: Does it produce a lot of dust?
• No. Because it is a wet granulation process and the machine is fully enclosed, it generates very little dust compared to dry granulation methods. This creates a cleaner and safer working environment in your factory.
• Question 4: What capacity can this machine handle?
• We manufacture a range of models with capacities from 1 ton per hour up to 8 tons per hour. This makes it a perfect fit for small, medium, and medium-large organic fertilizer production plants.

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.
