Diverse options for bio-organic fertilizer production line configuration: Meeting different production needs

by organic fertilizer production line

A bio-organic fertilizer production line usually includes several core sections. This basic setup ensures organic waste gets systematically processed into high-quality organic fertilizer.

What Mainly Affects the Configuration Differences

1.Raw Material Type: Different materials like livestock manure, crop straw, or food waste need different pre-processing equipment.

2.Production Scale: Smaller lines might simplify some steps, while large-scale ones need high automation.

3.Final Product Requirements: Powdered or granulated fertilizer need different finishing equipment.

Common Differences in Setup Options

1.Fermentation System Choice: Trough-type turners suit small to medium production, while tower fermenters are better for large-scale, continuous operation. Choosing between aerobic and anaerobic fermentation systems also changes the overall setup.

2.Granulation Process Differences: The choice between disc granulators or rotary drum granulators depends on the raw material and the required granule type. Each granulation method needs matching drying and cooling equipment.

3.Automation Level: From semi-automatic to fully automatic lines, the setup of control systems and monitoring equipment varies a lot. This directly impacts investment costs and labor needs.

4.Environmental Equipment Setup: The level of bio-deodorization systems and wastewater treatment equipment depends on how sensitive the factory location is. Plants near cities usually need more complete environmental protection facilities due to regulations.

In short, bio-organic fertilizer production lines need custom setups based on the specific situation. This ensures the line is both cost-effective and meets environmental standards, turning organic waste into a resource for sustainable goals.

How to improve the granulation rate of the disc granulator

by organic fertilizer production line

The granulation rate of the disc granulator directly affects the production efficiency and quality of organic fertilizer. When processing organic fertilizer raw materials containing high fiber and impurities, the disc granulator can take the following measures to ensure the uniformity and granulation rate of the particles:

Pretreatment of raw materials: For raw materials with high fiber and many impurities, it is necessary to first remove large impurities and long fibers through crushing and screening to make the material texture more uniform, provide high-quality basic materials for granulation, and reduce granulation failure caused by uneven raw materials.

Adjust the disc parameters: According to the characteristics of the material, reasonably adjust the disc inclination angle and speed. If the angle is too small, the material is easy to accumulate; if the angle is too large, the material residence time is short. Too fast speed will cause the material to be thrown out due to excessive centrifugal force, and too slow speed will make it difficult to fully roll and agglomerate. By repeatedly debugging and finding the appropriate parameters, the material can form a stable rolling track in the disc and promote uniform growth of particles.

Adding binder: By increasing the spraying amount and uniformity of the binder, the bonding of the material can be improved, thereby improving the strength and uniformity of the particles.

Install screening device: Install drum screener machine in the fertilizer production line to separate unqualified particles and impurities in time, return them to the granulator for reprocessing, form a closed loop, reduce the waste of raw materials, and ensure the uniformity of the output particles.

Clean the equipment regularly: Clean the disc and the inside of the disc granulator regularly to prevent the accumulation of impurities from affecting the granulation effect.

Through these methods, the disc granulator can stably maintain a high granulation rate, improve the quality and efficiency of organic fertilizer production, and help produce high-quality granular fertilizer.

How to choose between a rotary drum granulator and a disc granulator?

by organic fertilizer production line

In the fertilizer, feed and other industries, disc granulators and rotary drum granulators are both common granulation equipment, playing a key role in fertilizer production lines. Understanding their differences can help companies choose the right equipment and achieve efficient production.  From the working principle, when the disc granulator tilts the disc and rotates, the material continues to roll and agglomerate under the action of gravity, centrifugal force and friction. First, small particles are formed at the bottom of the disc, and then they continue to roll, absorbing the surrounding powder and gradually become larger. After reaching a certain size, they overflow from the edge of the disc to complete the granulation. The material of the rotary drum granulator rolls continuously in the rotating drum, and through water or steam, the basic fertilizer and other materials are fully reacted chemically in a wet environment, and the particles are agglomerated into balls under the extrusion force generated by the rotation of the cylinder. ​

In terms of equipment structure, the disc granulator is relatively simple. The core component is the tilted granulation disc, which is driven to rotate by the drive device. There are also disc inclination adjustment mechanisms, racks, feeding pipes, liquid sprayers, hanging plates, etc. The rotary drum granulator has a complex structure. The main body is a huge rotating cylinder, which is driven by a drive device. In addition, there are feeding systems, steam or gas supply systems, discharging systems, and complex control systems and auxiliary equipment such as temperature and humidity sensors. ​

The two have different focuses in their application areas. The disc granulator has a small investment and is easy to operate. It is a powerful assistant for small production plants and is widely used in small compound fertilizer plants, feed processing plants and small biomass fuel enterprises. The rotary drum granulator is like an industrial giant with high output and is suitable for large-scale production. It performs well in large-scale compound fertilizer and feed production enterprises and industrial raw material granulation processing. ​​

Disc granulators and rotary drum granulators have their own advantages and disadvantages. Enterprises must make comprehensive considerations and careful choices based on their own production scale, material characteristics, product quality requirements and budgets to win development opportunities in the fierce market competition.
