Factors Affecting the Production of Compound Fertilizers Using a Disc Granulator

by organic fertilizer production line

When producing compound fertilizers using a disc granulator, many factors influence granulation, such as disc diameter, disc speed, disc inclination, nozzle aperture, and moisture content. Generally speaking, disc inclination has a greater impact on the granulation rate, while disc speed has a greater influence on the compressive strength of the granules.

The moisture content of disc granulation significantly influences both the granulation rate and the compressive strength of the granules. When the moisture content of the material is controlled within the range of 16%-20%, the granulation rate and compressive strength of the granules are optimal. Too little moisture results in a low granulation rate; too much moisture causes the material to clump and stick together, resulting in a reduced granulation rate. When the moisture content is too low, the compressive strength of the granules increases with increasing moisture content, which is beneficial for improving the compressive strength of the granules. However, when the moisture content is too high, the excess moisture disrupts the interactions between fertilizer molecules, causing the dried granules to crack and resulting in a decrease in compressive strength. Before using a disc granulator, the optimal moisture content, disc speed, and disc inclination angle should be tested to ensure high fertilizer production line efficiency and high pellet quality. Furthermore, the finer the raw material powder, the better the granulation effect.

Disc granulators are widely used in organic fertilizer production lines and compound fertilizer production lines. Fertilizer production using disc granulators offers low investment, high output, simple process, and intuitive operation, resulting in excellent economic and social benefits.

The role of uniform feeder in fertilizer production line

by organic fertilizer production line

In the continuous process of fertilizer production, the uniform feeder is the “nerve center” to ensure the coordinated operation of all links. Whether in compound fertilizer production line or organic fertilizer production line, it can improve the stability of raw material supply by more than 50%, and reduce product quality fluctuations from the source.

The uniform feeder adopts a design combining spiral conveying and frequency conversion speed regulation. The conveying screw is made of wear-resistant alloy material, which can adapt to raw materials with different physical properties such as urea granules, phosphate rock powder, fermented organic fertilizer, etc. The feeding amount can be set with an accuracy of ±2%. It can automatically adjust the conveying speed according to the needs of subsequent crushing, mixing, granulation and other processes to avoid raw material accumulation or feed interruption.

In the compound fertilizer production line, it can accurately convey basic raw materials such as nitrogen, phosphorus, and potassium according to the ratio, so that the nutrient deviation in the mixing link is controlled within 2%, which is much better than 8% of manual feeding. When handling wet organic fertilizer raw materials, its anti-blocking spiral structure combined with the vibration device can effectively avoid material adhesion and blockage, ensuring that the feeding amount per minute is stable at more than 98% of the preset value.

Compared with traditional feeding equipment, the uniform feeder does not require frequent manual adjustment, can reduce 80% of operational intervention, and reduce energy consumption by 30%. The material level sensor equipped with the equipment can monitor the inventory of the silo in real time, automatically start and stop the feeding, and realize unmanned continuous operation.

Whether it is connected to the crushing equipment or the mixer, the uniform feeder can lay a good foundation for the subsequent processes through the stable supply of raw materials. Choosing an appropriate uniform feeder can make the fertilizer production process smoother, the product quality more stable, and demonstrate the core value in large-scale production.

Maintenance Secrets: Keep Your Rotary Drum Granulator “Forever Young”

by organic fertilizer production line

On the fertilizer production line, the rotary drum granulator works like an indefatigable iron warrior. But even the sturdiest equipment needs careful maintenance to stay in top condition. Master these maintenance tips to keep your equipment as good as new and boost production efficiency.

Daily Checks: Prevention is Better Than Cure

Before starting each day, spend 10 minutes on a “full physical exam”: gently shake connection points to check tightness, listen for abnormal “groans” from the transmission, and observe whether the drum rotates as smoothly as a ballet dancer. Don’t forget to check the spray system’s “blood vessels”, ensuring each nozzle can “spit water” freely.

Pro Tip: Create a visual checklist for daily inspections to avoid omissions.

Periodic Maintenance: Deep Care Program

Give your equipment a weekly “SPA”: carefully check whether the drum’s wear-resistant lining shows “wrinkles” (wear), and whether support rollers are “malnourished” (insufficient lubrication). Monthly, take the motor and reducer’s “temperature” (preferably below 70°C) and listen to their “heartbeat” (vibration frequency). Quarterly, conduct a comprehensive “physical exam” covering everything from transmission systems to electrical controls.

The Art of Cleaning: Equipment Loves “Baths” Too

After production, don’t let material residues “stay overnight” in the drum. A pressure washer is your best helper, easily removing most “stubborn elements”. For particularly “clingy” residues, special scrapers serve as your “scalpel”. Regular cleaning of surface grease and dust maintains “skin” cleanliness for early problem detection.

Lubrication: The Equipment’s “Lifeline”

Lubrication is like the equipment’s “circulatory system” – reducers need a “blood change” (gear oil replacement) every 1000 operating hours, while bearings require “blood transfusions” (grease replenishment) every 500 hours. Remember: different parts need different “blood types”, and too much or too little affects “health”.

Common Mistake: Mixing lubricants or using expired oils accelerates component wear.

Core Component: Special Care for the Drum

The drum is the equipment’s “heart” – pay special attention to its “figure” (deformation) and “immune system” (sealing performance). Slight “arrhythmia” (unsteady rotation) may signal serious issues requiring professional “doctor” diagnosis.

Nervous System: Electrical Maintenance

Regularly “take the pulse” of electrical systems: check for “tense nerves” (aged/loose connections) and control cabinet component responsiveness. Dust is circuit boards’ “nemesis” – regular cleaning prevents mysterious “neuroses” (electrical faults).

Application of Disc Granulators in NPK Fertilizer Production Lines

by organic fertilizer production line

In the NPK fertilizer production line, disc granulators are a widely used and highly favored granulation equipment.

The disc granulator‘s structure is relatively simple yet unique. It primarily consists of an inclined disc, a drive mechanism, and a spray system. The disc, the core of the granulation process, is typically constructed of high-strength steel to ensure it can withstand the various forces involved in the granulation process. The drive mechanism provides stable rotational power to the disc, ensuring it rotates at an appropriate speed.

The disc’s operating principle is based on the movement and interaction of the materials within the rotating disc. When the mixed NPK fertilizer raw materials are fed into the rotating disc, the disc’s tilt and rotational motion cause the materials to roll upward along the disc’s inner wall due to a combination of centrifugal force, friction, and gravity. During this rolling process, a spray system applies a binder to the material. The binder acts like “glue,” gradually binding the loose raw material particles together and causing them to aggregate and grow. Over time, these agglomerated particles continuously roll and collide within the disc, further compacting and shaping them, ultimately forming relatively uniformly sized round granules that roll off the disc’s edge, completing the granulation process.

Disc granulators offer numerous advantages. First, they produce fertilizer granules with high roundness, excellent appearance, and strong market competitiveness. Second, they are relatively simple to operate and easy to master, requiring minimal operator skill. Furthermore, disc granulators are highly adaptable and can produce fertilizer granules of varying sizes to meet diverse market demands by adjusting parameters such as disc speed, tilt angle, and binder spraying rate to meet specific production needs.

However, disc granulators also have limitations. For example, compared to some large-scale granulation equipment, their production efficiency may be relatively low, making them less suitable for large-scale industrial production. Furthermore, when processing high-viscosity raw materials, material may stick to the disc, affecting granulation efficiency and equipment operation. Nevertheless, due to their unique advantages, disc granulators still play an important role in the production of NPK compound fertilizers by small and medium-sized enterprises, as well as in production scenarios where the appearance of fertilizer granules is a high priority.

It expertly transforms various organic wastes into valuable “black gold,” revolutionizing the composting process. Let’s uncover its working secrets.

Did you know? A medium-sized crawler compost turning machine  can process organic materials equivalent to the weight of 3 adult elephants per hour! Its unique track design allows it to operate effortlessly on muddy terrain where conventional equipment would struggle.

The Transformation Journey from Waste to Fertilizer

The composting process begins with careful ingredient preparation. Operators need to precisely control the “recipe” like bakers—mixing livestock manure (nitrogen source) with straw (carbon source) at a golden ratio of 25-30:1, adjusting moisture to the ideal 55%-60%. At this point, the material should achieve the perfect texture of “forming a ball when squeezed but crumbling when dropped.”

Four Superpowers of Crawler-Type Turners

1. Terrain Conqueror: With its track design, it easily handles 15-degree slopes and post-rain muddy fields, like an off-road vehicle among tractors, increasing site utilization by 30% compared to traditional groove-type systems.

2. Efficiency Master: With processing capacity of 50-150 tons per hour and adjustable hydraulic turning arms, it can handle piles up to 2.5 meters high, working 1.5-2 times more efficiently than spiral turners.

3. Uniformity Expert: Unique turning teeth design ensures over 95% material turnover rate with temperature variation controlled within 3℃, guaranteeing even fermentation for every inch of material.

4. Versatile Performer: From sticky pig manure to dry straw, it can process various materials without part replacement, truly the Swiss Army knife of organic fertilizer production.

Intelligent Fermentation Management

The fermentation process resembles a carefully orchestrated symphony: initial stage (1-3 days) rapidly heats to 50-60℃; high-temperature phase (4-10 days) maintains 60-70℃ to kill pathogens; cooling period (11-20 days) promotes humus formation. Experienced operators adjust turning frequency based on temperature changes. Typically after 15-25 days, the materials transform into high-quality organic fertilizer—dark brown in color with an earthy fragrance.

Modern crawler compost turning machine s have evolved into intelligent versions equipped with temperature sensors and GPS tracking systems, bringing traditional composting into the era of digital agriculture.

This precisely proportioned fertilizer acts like a nutrient package tailored to the crop, improving fertilizer utilization and avoiding waste caused by nutrient imbalances. In addition, precise mixing helps improve the quality of agricultural products. A reasonable nitrogen, phosphorus, and potassium ratio can enhance crop resistance to pests and diseases, reduce pesticide use, and improve fruit color, flavor, and sugar content, thereby enhancing the market competitiveness of agricultural products.

Furthermore, precisely mixed NPK fertilizer production lines offer significant flexibility, allowing for rapid adjustment of formulations based on regional soil fertility and crop characteristics. Suitable fertilizers can be produced for acidic and alkaline soils, grain crops, cash crops, and horticultural crops.

Precise mixing also plays a positive role in environmental protection, reducing soil compaction and eutrophication caused by excessive fertilizer nutrients. The precise mixing of fertilizers produced by NPK compound fertilizer production lines, with its scientific and efficient formulations, has injected strong momentum into the sustainable development of modern agriculture.
