How to Improve the Efficiency of a New Two-in-One Organic Fertilizer Granulator

by organic fertilizer production line

The efficiency of a new type two-in-one organic fertilizer granulator directly affects the production capacity of an organic fertilizer production line. Improper operation can easily lead to problems such as slow granulation and low pelletizing yield. Four optimization strategies can improve both efficiency and quality.

First, proper raw material pretreatment is essential. Strict control of raw material particle size and moisture is crucial: crush the fermented organic fertilizer into a 40-60 mesh fine powder to prevent coarse particles from blocking the equipment’s feed inlet and affecting mixing uniformity. The moisture content should be maintained at a stable 25%-35%. Adjust moisture content by drying or adding dry materials; spray water if too low.

Second, precise adjustment of equipment parameters is crucial. During the mixing process, adjust the agitator speed according to the raw material type: when processing high-fiber raw materials (such as straw fertilizer), adjust the speed to 50-60 rpm to increase shear force; when processing highly viscous raw materials (such as chicken manure fertilizer), reduce the speed to 20-30 rpm to prevent material from sticking to the wall. During the pelletizing process, the pelletizing method should be adjusted to suit different raw materials: for high-viscosity raw materials, use agitator pelletizing, adjusting the disc inclination to 40°-45°; for high-fiber raw materials, use roller compaction pelletizing, increasing the die pressure appropriately.After parameter adaptation, the granulation efficiency of the new type two-in-one organic fertilizer granulator can be increased by 20%-25%, and the granule forming rate is stabilized at more than 90%.

Furthermore, daily maintenance is essential. Before starting the machine daily, inspect the agitator blades and pelletizing die for wear. If blade edge wear exceeds 3mm or the die aperture is deformed, replace them promptly to avoid uneven mixing and uneven pellet sizes caused by aging components. Clean residual material inside the equipment weekly, especially the mixing chamber and the inner wall of the pelletizing disc, to prevent material agglomeration that affects subsequent production. Lubricate transmission components such as bearings and gears monthly to reduce mechanical friction and extend equipment operation.

Finally, optimizing production processes can further improve efficiency. The “immediate recycling of screen residue” model allows the screening of substandard fines directly back to the mixing system through a reflux channel, eliminating the need for manual transfer and reducing waiting time for raw materials. If the organic fertilizer production line requires continuous operation, a raw material buffer can be configured to ensure uninterrupted feeding of raw materials, avoiding frequent equipment starts and stops due to material shortages. After process optimization, the equipment’s effective daily production time can be increased by 2-3 hours, increasing overall production capacity by approximately 15%.

The new type two-in-one organic fertilizer granulator’s complete operating process.

by organic fertilizer production line

The new type two-in-one organic fertilizer granulator features an integrated “mixing + granulation” design, simplifying organic fertilizer production. Its operations are centered around four core steps, ensuring pellet quality and efficiently supporting the organic fertilizer production line.

The first step is raw material pretreatment. Fermented organic fertilizer (such as livestock manure and composted straw) must first be crushed to a 40-60 mesh fine powder with a moisture content of 25%-35%. Excessively coarse raw materials will result in uneven granulation, while inappropriate moisture content will affect the final product. Meeting pretreatment standards is essential for stable equipment operation.

The second step is the core mixing process. Pretreated raw materials enter the integrated mixing system. A high-strength alloy steel agitator shaft drives the wear-resistant blades, while a variable frequency motor precisely controls the speed between 20-60 rpm. If binders such as bentonite are required, they are added simultaneously. The blades shear and stir the powder, achieving over 90% mixing uniformity within 5-10 minutes, preventing uneven nutrient distribution in the pellets.

The third step is targeted granulation. The mixed material automatically enters the granulation system, where the equipment changes its forming method based on the raw material’s characteristics. Highly viscous raw materials (such as chicken manure organic fertilizer) use a stirring granulation mechanism, where paddles knead the material into 2-4mm pellets. High-fiber raw materials (such as straw organic fertilizer) use a roller-type granulation mechanism, where die extrusion forms the pellets. The stainless steel disc can be hydraulically adjusted from a 30° to 50° tilt angle, and a wear-resistant rubber lining reduces sticking to the wall. The pellet formation rate exceeds 90%, and the pellets are uniformly shaped.

Finally, the screen residue is recycled and connected. After granulation, the pellets pass through an integrated screening device. Qualified pellets enter the drying stage (dried to a moisture content of less than 10%), while substandard fines are returned to the mixing system through a recirculation channel for processing with new raw materials. This design achieves a raw material utilization rate exceeding 95%, reducing waste and ensuring continuous production.

The entire process eliminates the need for frequent manual handling. The new type two-in-one organic fertilizer granulator can complete the entire process from raw material input to qualified pellet output, significantly improving the efficiency and convenience of organic fertilizer production.

Drum fertilizer cooler selection: Consider key dimensions and avoid common mistakes

by organic fertilizer production line

Choosing the right drum fertilizer cooler not only ensures effective material cooling but also reduces subsequent operating costs. However, when selecting a drum fertilizer cooler, it’s easy to fall into the trap of focusing solely on throughput, overlooking key factors like material properties and operating requirements.

First, clarifying the material properties is essential. Differences in moisture, particle size, and viscosity between materials directly impact cooling performance. For example, high-humidity materials tend to adhere to the drum’s inner walls, so a model with internal scrapers or special liners should be selected to prevent material accumulation. For fine powders, sealing performance is crucial to prevent dust leakage during cooling, requiring efficient, sealed feed and discharge devices. Ignoring material properties can lead to uneven cooling and equipment blockage, even if the throughput is appropriate.

Second, determine the cooling method based on cooling requirements. If the material needs to be cooled quickly and has no special requirements for the cooling medium, forced air cooling can be chosen to improve cooling efficiency by increasing air volume. If the material temperature is extremely high (over 600°C) or needs to be protected from air contact, jacket cooling is preferred. This uses thermal oil or cold water for indirect cooling, minimizing material contact with the outside world.

Finally, drum fertilizer cooler parameters should be tailored to the operating conditions. Consider the workshop space (determining drum length and diameter), power supply voltage (matching drive motor parameters), and ease of maintenance (ease of disassembly and cleaning). For example, if workshop height is limited, a horizontally arranged short-drum machine may be appropriate. If continuous production is essential, a machine with fault alarms and automatic cleaning features should be selected to minimize downtime for maintenance.

Advantages of Rotary Drum Granulators over Disc Granulators

by organic fertilizer production line

When selecting organic fertilizer granulation equipment, both rotary drum and disc granulators are commonly used. However, rotary drum granulators, with their multi-dimensional performance advantages, better meet the efficiency and scale requirements of modern organic fertilizer production lines. The differences between the two are primarily reflected in the following four aspects.

More flexible capacity adaptability meets the needs of large-scale production. Disc granulators are limited by the diameter of their discs, typically with an hourly output of 0.5-5 tons per unit, making them suitable only for small production lines. By adjusting the drum length and diameter, rotary drum granulators can achieve hourly outputs of 1-20 tons per unit. They meet the basic production needs of small and medium-sized enterprises as well as the large-scale production of large factories. They eliminate the need for multiple units in parallel, reducing production line floor space and equipment investment costs.

They offer greater raw material compatibility and reduce pretreatment complexity. Organic fertilizer raw materials have large fluctuations in moisture and composition. Disc granulators must maintain a moisture content of 20%-30%. They also struggle with crude fiber materials, which tend to stick to the disc and produce uneven granules. Rotary drum granulators can process materials with moisture levels of 25%-40%. Leveraging the multi-directional force of the rotating drum, they can smoothly granulate composted straw, livestock manure, and other materials without the need for additional crushing or conditioning, streamlining the process.

The resulting product is more stable and meets standardized requirements. Due to the single direction of centrifugal force, disc granulators produce pellets with a roundness of 70%-80% and large particle size variations. Rotary drum granulators, on the other hand, utilize internal rollers to guide and rotate the pellets, resulting in a fully rolling and shaping process with a roundness exceeding 90% and a precisely controlled particle size of 2-5mm. Furthermore, the granulation process is gentle, does not damage organic matter, and the pellets are of moderate strength. Transportation losses are 15%-20% lower than those from disc granulators.

Operation and maintenance are also simplified, resulting in lower long-term costs. Disc granulators require frequent manual adjustments of inclination and speed, resulting in wear and tear on the disc edges and requiring frequent replacement. Rotary drum granulators, on the other hand, utilize automated control to precisely adjust speed and feed rate, eliminating the need for manual oversight. The drum is constructed of wear-resistant stainless steel, resulting in a 40% lower failure rate and over 30% lower maintenance costs, resulting in superior long-term economics.

In summary, the advantages of the rotary drum granulator in terms of production capacity, raw material compatibility, finished product quality, and cost control make it ideally suited to the diverse needs of organic fertilizer production lines, making it an ideal choice for improving efficiency and competitiveness.

The Core Reasons to Choose a Rotary Drum Granulator for Organic Fertilizer Production Lines

by organic fertilizer production line

In the granulation stage of organic fertilizer production lines, rotary drum granulators are the preferred equipment for most companies due to their high adaptability to the characteristics of organic fertilizers. Their unique operating principle and performance advantages effectively address key challenges in the granulation process, ensuring product quality and production efficiency.

In terms of granulation adaptability, rotary drum granulators perfectly match the characteristics of organic fertilizer raw materials. Organic fertilizer raw materials, mostly livestock and poultry manure and composted straw, have complex compositions and contain a large amount of fiber. The rotary drum granulator uses the centrifugal force, extrusion force, and friction generated by the rotating drum to granulate loose raw materials without excessive compression, thus preventing the destruction of organic matter and functional microbial activity in the raw materials due to strong compression. The rotary drum granulator also adapts to fluctuations in raw material moisture content (it can handle raw materials with a moisture content of 25%-40%), reducing the tedious pre-treatment process.

The advantages in granulation efficiency and finished product quality are significant. The drum length and diameter of the rotary drum granulator can be flexibly designed to meet production capacity requirements. A single unit can achieve an output of 1-20 tons/hour, meeting the needs of production lines of varying sizes. Its granulation process is gentle and uniform, resulting in highly rounded granules (over 90% roundness). The particle size can be controlled between 2-5mm by adjusting the drum speed and the baffle, meeting standard requirements for organic fertilizer granules. The granules also possess moderate strength, preventing breakage during transportation while slowly disintegrating in the soil, enhancing nutrient release efficiency.

From a cost and environmental perspective, the rotary drum granulator is also competitive. Its simple structure, minimal transmission components, and low failure rate mean ongoing maintenance costs are approximately 30% lower than those of other granulation equipment (such as disc granulators and extrusion granulators). Furthermore, the granulation process does not require the addition of large amounts of binders; granulation is achieved solely through the raw material’s inherent viscosity. This reduces raw material costs while preventing the impact of foreign matter on the purity of the organic fertilizer, aligning with green production principles.

The comprehensive advantages of the rotary drum granulator in adaptability, efficiency, cost and environmental protection make it an ideal choice for the granulation link of the organic fertilizer production line, providing strong support for enterprises to achieve high-quality and high-efficiency production.

Differences in Equipment Selection Between Wet and Dry Granulation in the Fertilizer Industry

by organic fertilizer production line

In fertilizer production, granular fertilizers are widely used due to their advantages such as ease of application and uniform nutrient release. The differences in equipment selection between wet and dry granulation directly impact fertilizer quality and production efficiency, requiring precise matching based on fertilizer characteristics.

In the fertilizer industry, wet granulation focuses on “liquid-solid granulation,” and equipment selection is designed around nutrient dissolution and granule solidification. Key equipment is a rotary drum granulator or disc granulator. A rotary drum granulator uses a rotating, tilted drum to mix fertilizer powder with liquid raw materials such as phosphoric acid and ammonia, forming granules through the bonding force between the materials. This makes it suitable for producing nitrogen, phosphorus, and potassium compound fertilizers, ensuring uniform coating of multiple nutrients. A disc granulator uses high-speed rotation to generate centrifugal force, which forces the material and binder to form spherical granules. This makes it suitable for fertilizers such as organic fertilizers that require a fluffy structure. A drum fertilizer dryer is required to remove excess moisture from the granules using hot air, preventing fertilizer clumping and nutrient loss. This is a hallmark of wet granulation in the fertilizer industry.

Dry granulation requires no liquid addition, and the equipment used focuses on “physical extrusion shaping,” making it more suitable for heat-sensitive or water-soluble fertilizers. The core equipment is a double roller press granulator, which uses a pair of rollers to press fertilizer powder into dense flakes. This is then crushed and sieved to form granules, preventing moisture from deliquescing in fertilizers like urea and ammonium nitrate, while also minimizing nutrient volatilization. Some high-hardness raw materials require a crusher to pre-process the lumpy fertilizer into a fine powder to ensure uniform feeding. Dry granulation eliminates the need for drying equipment, streamlines the process, and preserves water-soluble nutrients, making it suitable for producing water-soluble or slow-release fertilizers.

When selecting fertilizers, wet granulation equipment is preferred for producing compound fertilizers requiring high nutrient content. Dry granulation equipment is more suitable for processing heat-sensitive, soluble fertilizers. Wet granulation equipment also consumes more energy and is suitable for large-scale production, while dry granulation equipment occupies less space and is more suitable for small- to medium-volume production of specialty fertilizers.

A deep dive into fertilizer crusher: Structure, Principle, and Core Advantages

by organic fertilizer production line

As a crucial piece of equipment in the fertilizer production process, fertilizer crushers play an indispensable role in the production of organic fertilizers, NPK fertilizers, and other fertilizers. To fully maximize their performance, a thorough understanding of their structure, operating principles, and core advantages is essential.

Structurally, a fertilizer crusher primarily consists of a crushing chamber, crushing components, a feed inlet, a discharge outlet, and a drive system. The crushing chamber provides space for material crushing. The crushing components within, such as the blades, hammers, and toothed plates, are the core components that directly act on the material. The drive system provides power to the crushing components, ensuring stable operation. Some fertilizer crushers are also equipped with a screening system to select the particle size of the crushed material to meet different production requirements.

The operating principle is based on a combination of impact, cutting, and grinding. After material enters the crushing chamber through the feed inlet, the high-speed rotating crushing components cut and grind the material. This, combined with intense collision and friction between the material and the crushing components, ultimately breaks the material into particles of the desired quality before discharging through the discharge outlet.

The core advantages of a fertilizer crusher lie in its high processing efficiency, adaptability, and ease of maintenance. It can quickly crush a variety of fertilizer raw materials, and its structural design facilitates routine maintenance and cleaning, significantly reducing production downtime and providing strong support for fertilizer manufacturers to increase production capacity.
