In the production of organic fertilizer, traditional granulation processes often require multiple pieces of equipment——such as mixers, granulators, and polishers——to operate in separate stages. This approach not only entails high equipment investment costs and significant space requirements but also leads to issues like material loss during transfer and inconsistent pellet formation rates. The new type two in one organic fertilizer granulator was developed specifically to address these pain points by integrating these functions into a single unit.

This equipment employs a continuous wet-process granulation method. It utilizes high-speed mechanical agitation and the resulting friction to continuously process fine powdered materials within the machine, completing the stages of mixing, granulation, spheronization, densification, and polishing.

The equipment consists of a main body, a granulation rotor assembly, and a drive system. The drive system and main body are mounted on a unified frame, resulting in a well-designed structure that ensures stable operation and ease of installation.

Working Principle of the New Type Two in One Organic Fertilizer Granulator

After entering the machine through the inlet, the material first passes through a primary stirring section, where a high-speed rotating stirring assembly subjects it to intense shearing and kneading; this breaks up large clumps and coarse fibers, allowing material particles to bond thoroughly and form initial fine granules. The granules then enter a secondary rotary drum chamber, where they undergo continuous rolling and collision driven by centrifugal and frictional forces; this process further densifies and polishes the granules, ultimately producing smooth, spherical pellets. The entire operation achieves “single-feed, continuous granulation” with the finished granules discharged from the opposite end of the machine.

What raw materials can the new type two in one organic fertilizer granulator process?

This equipment is compatible with a wide range of raw materials, including various organic substances:

Livestock and poultry manure: Fermented and decomposed chicken, pig, cattle, and sheep manure.

Agricultural by-products: Crop stalks, distillers' grains, furfural residue, mushroom substrate residue, medicinal herb residue, soybean dregs, etc.

Humic acid materials: Peat, lignite, weathered coal, etc.

Urban organic waste: Municipal sludge, sugar mill filter mud, papermaking sludge, etc.

The equipment is highly adaptable to materials with moisture content ranging from 20% to 40%; it is particularly effective at processing coarse-fiber materials and high-moisture, sticky materials that are difficult to granulate using conventional equipment. Materials are ready for production after undergoing thorough aerobic fermentation and decomposition, followed by pulverization and screening through a 40-60 mesh sieve.

What are the auxiliary facilities for the new type two in one organic fertilizer granulator?

The new type two in one organic fertilizer granulator can operate as a standalone unit or be integrated with upstream and downstream equipment to form a complete granular organic fertilizer production line. A complete supporting system typically includes:

Raw material processing equipment: Crushers (such as vertical crushers or half wet material crushers) and screening machines, used to reduce raw materials to the appropriate particle size and remove substandard particles.

Mixing equipment: Horizontal or twin-shaft paddle mixers, used to thoroughly blend raw materials, microbial strains, and additives.

Conveying equipment: Belt conveyors, bucket elevators, screw conveyors, etc., to facilitate the automatic transfer of materials between stages.

Drying and cooling equipment: Drum dryers to remove excess moisture from the granules, and coolers to lower the temperature for subsequent packaging and storage.

Screening equipment: Trommel screens to grade and sort the finished granules.

Packaging equipment: Automatic packaging machines to handle the packaging of the finished product.

Configuration flexibility: The actual setup can be flexibly configured based on production scale and site conditions, accommodating everything from small-scale lines producing a few thousand tons annually to large-scale lines with an annual output of tens of thousands of tons.

Key Advantages of the New Type Two in One Organic Fertilizer Granulator

The integrated design of this new type two in one organic fertilizer granulator combines crushing, mixing, granulating, and screening into a single unit, allowing raw materials to be fed directly without the need for separate pre-crushing. Equipment investment costs are reduced by over 40% compared to traditional modular systems, and the entire process can be operated by a single person. Key components are constructed from wear-resistant and corrosion-resistant materials, enabling the processing of various organic raw materials—including those prone to clumping due to moisture or characterized by high coarse-fiber content. The granulation rate consistently exceeds 90%, yielding round, uniform, and high-strength granules that meet the requirements for packaging, transport, and field application.
