Different fertilizer types require special adaptation requirements for ring die granulators

fertilizer granulator Sep 29, 2025

In fertilizer production, ring die granulators must adjust core parameters based on the characteristics of different raw materials, such as organic fertilizer, compound fertilizer, and slow-release fertilizer, to ensure optimal granulation.

For organic fertilizers, whose raw materials often contain fiber components such as straw and fermented manure, ring die granulators require large-aperture ring dies (typically 8-12mm) and anti-entanglement rollers to prevent fiber entanglement and pelletizing stalls. Furthermore, the steam injection time should be appropriately extended during the conditioning stage to enhance the viscosity of the fiber raw material.

If producing bio-organic fertilizers containing live bacteria, a rapid cooling device should be added after granulation to reduce the pellet temperature to below 35°C to prevent high temperatures from killing the live bacteria.

Compound fertilizer raw materials are primarily nitrogen, phosphorus, and potassium powders, which are prone to moisture absorption and agglomeration. Therefore, granulators require ring dies made of wear-resistant materials (such as alloy steel) to minimize wear on the die holes, and the roller pressure must be precisely controlled. Excessive pressure can cause components like nitrate nitrogen in the raw materials to decompose and be lost due to the high extrusion temperature, while too little pressure can cause the granules to become loose.

Slow-release fertilizers, however, contain special ingredients like coating agents, so the ring die granulator requires a lower extrusion temperature (below 30°C). This is usually achieved by reducing the roller speed (from 30 rpm to 20 rpm) and adding a cooling device to prevent high temperatures from damaging the slow-release coating structure and ensure the fertilizer’s slow-release effect.

Practical optimization directions for energy saving and consumption reduction in fertilizer coating machines

Currently, fertilizer companies are focusing on controlling production costs. Through proper optimization, coating machines can achieve energy savings and consumption reduction, helping companies lower operating costs.

First, energy saving in the heating system. Some coating machines utilize a waste heat recovery design. A heat exchanger is installed at the heat sealing channel outlet to collect the exhaust hot air and preheat the incoming cold air, reducing heat consumption in the heating tubes. This design reduces heating energy consumption and is particularly suitable for companies with continuous production, with significant energy savings over the long term. Furthermore, variable frequency heating tubes are used, which automatically adjust power based on particle flow rate. For example, when production capacity drops to 50%, heating power is also reduced, avoiding high-temperature operation and wasting energy during idle periods.

Second, motor frequency conversion modification. The equipment’s conveyor belts, film reels, and other motors utilize variable frequency control. During production, the PLC system is linked to a particle flow sensor to automatically adjust motor speed based on particle flow rate. Compared to traditional fixed-speed motors, variable-frequency motors can save 10%-12% of electricity, operate more smoothly, and reduce noise by 5-10 decibels, improving the workshop working environment.

Third, film utilization is improved. Some coating machines support adaptive film width adjustment. When changing films of different widths, manual adjustment of the film guide mechanism is eliminated, and the optimal wrapping width is automatically matched. This reduces material loss during the commissioning process. Long-term use can significantly reduce raw material procurement costs, supporting enterprises in reducing costs and increasing efficiency.

Working principle of the fertilizer granule coating machine: Core design adapted to fertilizer characteristics

fertilizer granulator Sep 28, 2025

In fertilizer production, the core function of the coating machine is to address the issues of loose granules and their tendency to absorb moisture and agglomerate. Its workflow is precisely designed based on fertilizer characteristics.

First, during the granule conveying process, the coating machine utilizes an “anti-scattering conveyor belt + vibrating discharge mechanism” to prevent granule accumulation. A flow sensor controls the conveying rate, ensuring that each batch of granules enters the coating area evenly. Even with materials with complex ingredients and uneven particle sizes, such as compound fertilizers, this ensures a uniform distribution of granules of varying sizes, paving the way for subsequent coating.

Next, the film wrapping process occurs. To prevent fertilizers from absorbing moisture, PE or PP film is often used. A film guide mechanism, combined with a particle deflector, tightly wraps the granules from all sides. An adaptive tension system adjusts the film tension based on granule flow to prevent leakage or agglomeration. The heat-sealing and shaping process is particularly critical. The coating machine utilizes hot air circulation to achieve film shrinkage while preventing the loss of fertilizer components due to high temperatures. For example, urea fertilizers are prone to decomposition above 160°C, and precise temperature control maximizes nutrient retention. Zoned temperature control also prevents localized overheating that can lead to pellet clumping, ensuring that pellets remain loose after coating.

Finally, the packaging is cut to pre-set specifications and the bag opening is simultaneously compacted to ensure packaging integrity. This process addresses both fertilizer storage and transportation requirements, ensuring that the packaging is protected from damage and leakage, even during bumpy long-distance transport.

Energy-saving optimization of drum fertilizer coolers: Practical methods to reduce operating costs

fertilizer granulator Sep 26, 2025

With the general trend of reducing costs and increasing efficiency in industrial production, energy-saving optimization of drum fertilizer coolers has become a key focus for many companies. In fact, without major equipment modifications, adjusting operating parameters and optimizing system configuration can effectively reduce energy consumption and operating costs.

First, optimize cooling medium recycling. A circulation device can be added to the cooling system. For example, warm water discharged from the jacket can be directed to a cooling tower for cooling and then recirculated back to the jacket for reuse, reducing fresh water usage. For forced air cooling, the warm exhaust air can be cooled through a heat exchanger before being re-circulated into the drum as cooling air, reducing fan energy consumption.

Second, adjust drum fertilizer cooler operating parameters to suit production needs. Parameters can be dynamically adjusted based on the material’s real-time temperature and processing volume. For example, if the material feed temperature is lower than expected, the drum fertilizer cooler speed can be appropriately reduced to extend the material’s residence time and reduce the cooling medium flow rate to avoid overcooling. When processing volume decreases, the drive motor speed can be reduced to reduce motor energy consumption.

Third, add insulation to reduce heat loss. If the drum shell is exposed to air for extended periods, it will dissipate heat into the surrounding environment, increasing the load on the cooling system and causing energy loss. Installing an insulation layer (such as rock wool or aluminum silicate fiber) between the drum shell and the jacket can reduce heat radiation from the shell. Also, insulate the pipes at the feed and discharge ports to prevent the material from absorbing ambient heat during transportation, which would increase the cooling load.
