How much fertilizer can a one ton pig manure organic fertilizer production line produce

fertilizer granulator Dec 10, 2024

The specific output of converting one ton of pig manure into organic fertilizer in an organic fertilizer production line is influenced by various factors, including but not limited to the following:

Fermentation method: Dry fermentation often produces more solid products compared to wet fermentation because there is more water loss during the wet fermentation process.

Adding substances: If fillers (such as sawdust, rice husks, straw, etc.) are added during the fermentation process, it will increase the volume and weight of the final product.

Fermentation efficiency: The loss rate during the fermentation process is also an important factor, including incompletely degraded residues, evaporated water, and the portion that becomes gas emissions (mainly carbon dioxide and ammonia).

Finished product requirements: If the finished product needs to be dried, the removal of moisture will further reduce the weight of the final product.

Product form: Compared to granular fertilizers, powdered fertilizers occupy a larger volume under the same weight.

General assumption

Assuming good fermentation efficiency and no additional substances are added,

Preliminary estimates suggest that approximately one ton of fresh pig manure (with a moisture content of about 80%), after sufficient fermentation and drying treatment, can yield about 200 to 400 kilograms of dry weight organic fertilizer. This scope covers changes in most cases.

Actual case

Under certain conditions, especially when efficient fermentation techniques and refined management processes are employed, this number may reach even higher levels. For example, some advanced organic fertilizer production lines report that one ton of optimized pig manure can produce over 500 kilograms of high-quality organic fertilizer.

It is worth noting that the above data is for reference only, and the specific situation needs to be calculated based on your organic fertilizer production process, raw material status, and expected product quality. To obtain more accurate values, it is recommended to conduct small-scale testing of experimental batches or consult a professional organic fertilizer production consultant to evaluate your specific situation.

The granulation process of rotary drum granulator in NPK fertilizer production line

fertilizer granulator Dec 10, 2024

The rotary drum granulator (also known as rotary cylinder granulator or drum granulator) is widely used in NPK fertilizer (nitrogen phosphorus potassium compound fertilizer) production lines, and its unique granulation principle and high efficiency make it one of the mainstream equipment in the industry. The following is a basic introduction to the granulation process of the rotary drum granulator in the NPK fertilizer production line:

working principle

The working principle of the rotary drum granulator is mainly based on the centrifugal force and self-organization effect in physics:

When the moist mixed material enters the rotating cylinder, due to the centrifugal force, the material begins to roll along the cylinder wall.

At the same time, the internal tilt angle causes the material to move forward, and with appropriate moisture and binder, the material gradually aggregates into spherical particles.

The design of the plate inside the drum helps to achieve uniform distribution and rolling of materials, promoting the formation and growth of particles.

Key features

Continuous production: The rotary drum granulator supports large-scale and continuous production modes, suitable for large-scale industrial applications.

Strong adaptability: able to handle different types and characteristics of raw materials, including powder, sheet or fine particle materials.

Strong controllability: By adjusting the speed, inclination angle, moisture content, and adding auxiliary materials, the size, shape, and hardness of particles can be precisely controlled.

Granulation process flow

Material pretreatment: The mixed raw materials are transported by conveyor to the granulator for necessary crushing and premixing.

Granulation: The material enters the rotary drum granulator and forms balls through centrifugal force and self-organization effect.

Particle maturity: Under appropriate time and conditions, the particles continue to roll in the drum until they reach the desired size.

Discharge: Mature particles are discharged from the other end and enter the subsequent drying, cooling, and screening processes.

Technical optimization

To improve efficiency and product quality, modern rotary drum granulators are often equipped with advanced control systems, such as PLC programming, sensor monitoring, and data analysis software, to achieve precise control of parameters such as temperature, humidity, and speed.

conclusion

The rotary drum granulator plays an important role in NPK fertilizer and other fertilizer production lines due to its excellent granulation ability and wide adaptability. Its high efficiency and versatility make it an important tool for advancing modern agriculture and fertilizer industry. However, with the continuous innovation of technology, the design of rotary drum granulators will be further optimized in the future, moving towards higher productivity, lower energy consumption, and more environmentally friendly direction.
