For many enterprises, livestock farms, or farming cooperatives new to the organic fertilizer industry, selecting an organic fertilizer granulator is often a daunting task. The market offers a wide variety of granulators, with prices ranging from tens of thousands to hundreds of thousands of yuan. Manufacturers all claim their equipment is superior, but after purchasing, some users find that the machines frequently clog, fail to form proper granules, or produce yields below expectations—or even cause the entire production line to malfunction. In fact, through our experience serving numerous organic fertilizer projects, we have found that over 70% of equipment issues stem not from machine quality but from mismatched equipment selection during the initial planning phase. There is no “one-size-fits-all” model for organic fertilizer granulators; there is only equipment suited to your specific raw materials and production needs. To avoid wasting money, you must comprehensively consider five key factors during the selection process: raw materials, production capacity, sales channels, budget, and equipment quality.

Step 1: Assess the Raw Materials—They Determine the Machine Type

Through years of project experience, we have found that the vast majority of failed equipment selections are related to mismatched raw materials. For example, a livestock farm client used fermented chicken manure as their primary raw material. Seeing that the double roller granulator required a lower investment, they purchased and installed it directly. As a result, the high-moisture material frequently caused the rollers to jam upon entering the equipment, requiring the machine to be shut down for cleaning several times a day, leading to extremely low production efficiency. Subsequent raw material testing revealed that the moisture content of their chicken manure was nearly 35%, making it a typical high-moisture fermented material better suited for a wet-type stirring teeth granulator. After replacing the equipment, the granule formation rate improved significantly, and production returned to normal. Different raw materials require different equipment:

1. 1. High-moisture fermented manure
   For raw materials such as chicken manure, cow manure, sheep manure, and biogas slurry with moisture contents between 28% and 40%, we recommend selecting a stirring teeth granulator. This equipment utilizes high-speed rotating paddles for forced mixing and agglomeration into granules. It has strong adaptability to wet materials and can process feedstock without prior drying, making it particularly suitable for manure resource recovery projects at livestock farms.
2. 2. Dry Powder Organic Fertilizers and Bio-fertilizers
   For pre-dried materials such as humic acid powder, bio-fertilizers, and dry powder organic fertilizers with a moisture content between 10% and 20%, a double roller granulator is more suitable. This equipment employs a dry granulation process that requires no water addition or drying, thereby reducing energy consumption while preserving microbial activity.
3. 3. Premium Organic Fertilizer Production
   If the product is primarily targeted at the high-end fruit and vegetable cultivation market, a disc granulator is an excellent choice. The granules it produces are round and smooth with excellent appearance quality, making it easier to gain market recognition and command a premium price.
4. 4. Large-Scale Continuous Production
   For organic fertilizer plants with an annual output of over 50,000 tons, a drum granulator often offers greater advantages. It features high single-unit capacity and can achieve 24-hour continuous production, making it suitable for standardized, large-scale fertilizer processing projects.

Step 2: Determine Equipment Specifications Based on Output

Many customers believe that larger equipment is always better, but this is a common misconception. Oversized equipment not only increases procurement costs but also drives up facility, electricity, and maintenance expenses; conversely, undersized equipment will limit production capacity growth. The correct approach is to first calculate the actual hourly production requirement. For example, given an annual output of 20,000 tons of organic fertilizer, 300 production days per year, and 10 hours of operation per day, the actual hourly production requirement is approximately 0.7 tons. Under these circumstances, selecting a small-scale granulation unit with a capacity of 1–2 tons per hour is sufficient to meet the demand, and there is no need to invest directly in a large-scale drum production line. Matching capacity appropriately not only helps control investment risks but also improves equipment utilization.

Step 3: Select Granule Type Based on Sales Channels

Many people focus solely on whether granulation is possible, yet overlook the market’s requirements for granule shape. In reality, different sales channels have distinct granule requirements:

1. 1. If the product is primarily sold through supermarket chains, high-end fruit and vegetable farms, or gardening markets, standard spherical granules produced by disc granulators are more competitive and present a more aesthetically pleasing appearance after packaging.
2. 2. If the product is primarily used for field cultivation, long-distance transportation, or wholesale distribution, the granules produced by double roller granulators are harder and less prone to breaking during transport.
3. 3. For on-farm fertilizer use or local sales projects, stirring teeth granulators often offer a competitive advantage due to their lower overall cost.

Step 4: Beyond Equipment Price, Consider the Total Investment Cost

Many users focus primarily on equipment quotes when inquiring. In reality, the equipment price is only a portion of the total investment. Take the wet granulation process as an example: although standalone stirring teeth or disc granulators are less expensive, the granules they produce have a higher moisture content, typically requiring additional drying and cooling equipment. This can increase the investment for the entire production line by between 30% and 60%. In contrast, double roller granulators use a dry process that requires no drying equipment, resulting in lower long-term operating costs. Additionally, the following factors must be considered: whether the factory floor space meets installation requirements; whether the power supply is sufficient; the cost of replacing wear parts in the future; the difficulty of equipment maintenance; and the number of operators required. These hidden costs often warrant more attention than the equipment purchase price.

Step 5: Focus on Equipment Quality and Manufacturer Capabilities

Prices for similar equipment on the market vary significantly, with core differences typically lying in materials, manufacturing processes, and after-sales service. For example: high-quality agitator teeth are usually made of high-chromium wear-resistant materials, whereas ordinary carbon steel teeth may need to be replaced within a few months; high-quality double roller mills use 65Mn alloy steel roll shells, offering superior wear resistance; reputable manufacturers equip their machines with hardened-tooth gear reducers and variable-frequency speed control systems, ensuring more stable operation. Beyond the equipment itself, the manufacturer’s service capabilities are equally important. A truly experienced equipment manufacturer does more than just sell equipment; it assists customers with raw material analysis, process design, plant layout planning, installation and commissioning, as well as post-installation technical training.

Take Tianci Heavy Industry as an example. With over two decades of deep expertise in fertilizer equipment manufacturing, we have participated in hundreds of fertilizer projects, serving clients across multiple countries and regions. In actual projects, we consistently prioritize raw material analysis before designing solutions, rather than simply recommending equipment models. Only a solution that truly matches the client’s needs can help them achieve long-term, stable production.

Conclusion

Choosing an organic fertilizer granulator is not merely about selecting a machine; it is about selecting a production solution tailored to your specific development needs. Different raw materials, production capacities, and sales channels all result in completely different equipment configurations. We recommend thoroughly understanding your raw material characteristics and production goals before purchasing. If necessary, conduct trial runs with your raw materials to verify performance, and then make a decision based on technical advice from professional manufacturers. This approach not only prevents frequent retrofits and equipment idling down the line but also ensures that every investment delivers true value. For organic fertilizer producers, selecting the right equipment is just the beginning; establishing a stable, efficient, and sustainable production system is the key to long-term development.

In recent years, an increasing number of livestock farms, organic fertilizer plants, and compound fertilizer companies have begun planning fertilizer processing projects. However, when it comes to actual implementation, many clients encounter the same problem: while the equipment may look similar at first glance, they often find it “unsuitable for their needs” once production begins.

For some, raw materials have excessively high moisture content, leading to consistently poor granule formation; for others, limited space results in a disorganized production line layout; and for still others, while the equipment may be inexpensive initially, it suffers from severe wear and tear, high energy consumption, and frequent maintenance down the line. For many first-time fertilizer production line clients, the greatest challenge isn’t purchasing the equipment, but rather determining “which equipment truly suits their specific raw materials and production capacity.”
As a company with over 20 years of experience in fertilizer equipment manufacturing, Zhengzhou Tianci Heavy Industry Machinery Co., Ltd. has discovered through practical project experience that there is no “one-size-fits-all” solution for fertilizer equipment. A truly mature production line must be comprehensively designed based on factors such as raw materials, formulations, production capacity, site conditions, and climate.

For example, in organic fertilizer projects, the requirements for equipment vary significantly depending on the raw materials. High-moisture materials such as chicken manure, cow manure, and sheep manure place a greater demand on the stability of the fermentation system and turning equipment; whereas materials like sludge, microbial residue, and straw require higher standards for crushing, mixing, and subsequent granulation processes. If the initial process configuration is not properly matched, issues such as uneven fermentation, poor pellet strength, and high return rates are likely to arise later on.
Over the years, Tianci Heavy Industry has consistently adhered to the service philosophy of “understanding the raw materials first, then recommending equipment.” When clients initially consult, our technical team first thoroughly understands the raw material type, moisture content, daily output, target particle size, and site dimensions before developing a solution tailored to actual needs—rather than simply recommending a specific piece of equipment.

In the fermentation stage, turning equipment often determines the efficiency and stability of the entire organic fertilizer production process. For projects of varying scales, Tianci Heavy Industry offers a range of equipment solutions, including crawler type compost turner, chain plate type compost turner, groove type compost turner, and vertical fermentation tanks. For the continuous processing needs of large-scale livestock farms, chain plate type compost turner equipment is better suited for high-throughput operations; whereas for projects with limited space or stringent environmental requirements, vertical fermentation tanks can effectively shorten the fermentation cycle and reduce odor dispersion.

After actual use, many customers’ most immediate impression is not “how complex the equipment is,” but rather whether it operates stably and requires minimal maintenance. This is especially true for turning equipment: if the bearings, corrosion-resistant structures, or wear-resistant components are subpar, breakdowns and downtime are likely to occur before long. In manufacturing, Tianci Heavy Industry prioritizes long-term wear resistance and stability, minimizing the frequency of maintenance through optimized structural design and material processes.

In fertilizer production lines, the granulation stage is the absolute core. Different raw materials and fertilizer types require completely different granulation methods.
For example, double roller granulators are better suited for dry granulation scenarios such as compound fertilizers, organic fertilizers, and mineral powders. The equipment requires no drying, involves relatively low investment, and is suitable for some small and medium-sized projects; disc granulators, on the other hand, are more suitable for wet granulation of organic fertilizers and are frequently used in projects with high requirements for particle roundness; organic fertilizer granulators demonstrate strong adaptability to post-fermentation organic fertilizer raw materials and achieve high granulation rates, making them commonly used in organic fertilizer production lines; drum granulators, on the other hand, are suitable for high-capacity continuous production.

A common pitfall many clients have fallen into in the past is “focusing solely on equipment price without considering overall process compatibility.” In reality, even with the same type of granulator, the final granule quality can vary significantly depending on different formulations, moisture levels, and fiber content. The core value of the extensive project experience Tianci Heavy Industry has accumulated over the years lies in helping customers minimize trial-and-error costs.

Currently, Tianci Heavy Industry has obtained certifications for the Quality Management System (ISO 9001:2015), the Environmental Management System, and the Occupational Health and Safety Management System, and holds more than 20 utility model patents for equipment such as granulators, compost turners, crushers, dryers, and screeners. The company not only has dedicated R&D and production teams but also maintains installation and overseas after-sales service teams, providing clients with one-stop services ranging from solution design to equipment commissioning.

To date, our products have been sold to over 50 countries worldwide, including Africa, South America, the Middle East, and Southeast Asia, and we have successfully completed more than 500 projects. For many of these overseas clients, primary concerns extend beyond the equipment itself to include whether production can be maintained stably, ease of maintenance, and the timeliness of technical support. This is also a key reason why many clients continue to partner with us over the long term.

Today, competition in the fertilizer industry is intensifying. Equipment is no longer simply about “being able to produce”; factors such as energy consumption, stability, labor costs, and operational efficiency must also be considered. For companies planning to build new fertilizer plants or upgrade existing production lines, finding an equipment manufacturer that truly understands the process, raw materials, and on-site implementation is often more important than simply comparing prices.

Over the years, Zhengzhou Tianci Heavy Industry Machinery Co., Ltd. has remained dedicated to one goal: providing fertilizer equipment and production line solutions that are best suited for practical implementation based on customers’ actual needs. For many clients, high-quality equipment is not merely a machine; it is the cornerstone of stable production and long-term profitability.

Crop straw is also one of the important raw materials for producing organic fertilizers. Corn straw, wheat straw, rice straw and other crop straw contain abundant fiber and trace elements, which can improve soil structure, enhance soil permeability and water retention. The advantages of crop straw are its wide range of sources, low cost, and ability to improve soil structure. However, its disadvantages include low nutrient content, slow fermentation process, and the need to add an appropriate amount of animal manure or other organic waste to increase nutrient content.

Urban garbage is also one of the raw materials for making organic fertilizers. Urban waste includes household waste, kitchen waste, etc., which contains abundant organic matter and trace elements. Using urban waste to produce organic fertilizer can effectively reduce environmental pollution caused by waste and achieve resource utilization. However, urban waste may contain a large amount of non degradable substances such as plastics and metals, which require strict screening and treatment.

Mushroom residue is also one of the raw materials for making organic fertilizers. Mushroom residue is a waste generated during the cultivation process of mushrooms, which contains rich organic matter and trace elements. The advantages of mushroom residue are high nutrient content and wide applicability, but the disadvantages are high price and unstable source.

In summary, selecting the optimal combination of raw materials can produce high-quality organic fertilizers. According to the characteristics and advantages and disadvantages of different raw materials, organic fertilizers suitable for different plant needs and geographical environments can be combined. For example, in nitrogen deficient soil, animal manure with high nitrogen content can be used as the main raw material; In phosphorus deficient soil, crop straw with high phosphorus content can be used as the main raw material. At the same time, attention should also be paid to the treatment and sterilization of raw materials to ensure the safety and reliability of the produced organic fertilizer.

The more widely known name for the brown coal pelletizer is the ball press machine, mainly used in the production of low and medium nutrient compound fertilizers, as well as the granulation of organic, inorganic compound fertilizers, and elemental fertilizers.

Brown coal pelletizing is one application of the high-pressure double-roll granulation process. It involves compressing brown coal powder through the action of twin rollers, molding the powdered brown coal into spherical, cubic, or other granular forms. After molding, the qualified particles go through screening before entering the next stage of the process.

The brown coal pelletizer, as the main unit in the granulation production line, is divided into seven main stages:

1. 1.Raw Material Preparation: Initially, brown coal needs to be crushed and finely ground for subsequent processing.
2. 2.Binder Addition: A suitable amount of binder is added to the fine brown coal particles to bind them together and form granules.
3. 3.Mixing: The brown coal particles with added binder are mixed thoroughly to ensure proper binding.
4. 4.Pelletizing Machine: The mixed brown coal particles are fed into the pelletizing machine, where mechanical force is applied to shape them into granules.
5. 5.Drying: The formed granules undergo drying to remove excess moisture.
6. 6.Screening: The dried granules are screened to separate any non-conforming particles, ensuring product quality.
7. 7.Packaging: Qualified granules are packaged for sale or storage.

The entire brown coal pelletizing production line boasts high automation, elevated production efficiency, and the ability to effectively process brown coal into granules, thereby enhancing its added value and market competitiveness. Moreover, the production line employs advanced processes and equipment to guarantee product quality and production safety.
