5-8TPH Rotary Drum Granulation Production Line

The complete set of equipment for the 5-8TPH organic fertilizer granule production line mainly consists of organic fertilizer fermentation tanks, compost turners, organic fertilizer crushers, rotary drum granulators, rotary drum dryers and coolers, drum screening machines, automatic packaging machines, etc.

Organic fertilizer raw materials (livestock and poultry manure, domestic garbage, dead branches, and leaves, biogas residue, waste bacteria, etc.) enter the semi-(high) wet fermentation tank after fermentation. The material crusher crushes, and then adds nitrogen, phosphorus, potassium, and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to make the mineral elements contained reach the specified standards. Then use a mixer to stir, and then the particles enter the granulation mechanism and are dried after coming out. After screening by the screening machine, qualified products are packaged, and unqualified products are returned to the granulator for granulation.

5-8TPH organic fertilizer granule production line process:

The process flow and corresponding common equipment are introduced in detail below. Contact us and we will introduce you face-to-face to the equipment composition and construction planning scheme of an organic fertilizer production line with an output of 50,000 tons to 80,000 tons per hour, and provide an organic fertilizer production formula suitable for your needs:

Collect organic fertilizers

In the production process of organic fertilizer, organic raw materials including agricultural waste, livestock and poultry manure, plant straw, etc. need to be collected first. After these raw materials are collected, they will be initially sorted and processed to facilitate the subsequent production process.

Aerobic fermentation

The collected organic raw materials are sent to the aerobic fermentation pile after preliminary treatment. In an aerobic fermentation environment, microorganisms are encouraged to metabolize organic matter by providing sufficient oxygen, regulating humidity, and maintaining an appropriate carbon-nitrogen ratio.We provide two types of fermentation equipment: organic fertilizer fermentation tanks and turners. The turning machine is a traditional fermentation process. The specific differences are as follows:

Organic fertilizer fermentation tanks are usually sealed containers with appropriate ventilation facilities to ensure an adequate supply of oxygen and facilitate aerobic fermentation. After proper proportioning, ventilation, humidity control, and other conditions, organic raw materials are fully exposed to oxygen and fermented through the action of microorganisms. The compost turner turns and stirs the fermented organic materials to promote the uniformity and ventilation of the fermented materials.

Material crushing

The main purpose of this stage is to crush and crush the organic raw materials that have undergone aerobic fermentation for the subsequent granulation process. Generally, the organic materials that have undergone aerobic fermentation have become relatively loose in the fermentation pile, but to further improve the granulation effect, the materials need to be crushed into appropriate particle sizes. The organic fertilizer crusher we offer can effectively crush organic materials into the required particle size.

The process of material crushing not only helps to improve the granulation effect but also helps to improve the working efficiency of the subsequent granulator. Through scientific and efficient material crushing, it can ensure that the organic fertilizer particles obtain a more uniform and stable texture in the subsequent granulation process, thereby producing high-quality organic granular fertilizer that meets the requirements.

Material granulation

Material granulation is a key step in the production process of organic fertilizer. The organic raw materials after aerobic fermentation and material crushing are sent to the rotary drum granulator for granulation operation. At this stage, through the rotating drum, the raw materials are continuously subjected to the force of high-speed rotation and gradually form granules. During the granulation process, proper humidity and temperature control are crucial to ensure granule formation and stability. A certain amount of auxiliary wetting agent is usually added inside the granulator to improve the adhesion between raw materials and promote the formation of granules.

Finally, through the operation of the granulator, the organic raw materials are successfully transformed into uniform and stable organic fertilizer particles. These granules have good particle size and mechanical strength, and are convenient for storage, transportation, and application, providing convenience for the wide application of organic fertilizers. 

Fertilizer drying

Material shall be dried to enter the dryer. When the dryer is rotating, a series of internal fins will lift the material by lining the inner wall of the dryer. When the material reaches a certain height to roll the fins back, it will fall back to the bottom of the dryer, and then pass through the hot gas stream as it falls. Independent air heating systems, and centralized waste discharge result in energy and cost savings.

Fertilizer cooling

Rotary drum cooler removes fertilizer water and lowers temperature, used with rotary dryer in organic fertilizer and inorganic fertilizer production, which greatly increases cooling speed, and relieves work intensification. The rotary cooler also can be used to cool other powdered & granular materials.

7. Material screening

The purpose of screening is to remove fine particles or agglomerates between particles to ensure the uniformity and quality of the final product. The rotary screen machine divides the particles into different levels according to size by vibrating the screen surface, and can effectively remove particles that do not meet the requirements.

8. Material packaging

Unqualified fertilizer particles will be transported to the fertilizer crusher for further processing, and the finished products will be transported directly to the automatic fertilizer packaging machine.

Application of 5-8TPH Rotary Drum Granulation Production Line

The raw materials of this production line mainly include the following five types:

animal manure

The process flow of the organic fertilizer production line is more complicated than that of the powdered organic fertilizer production line. The main requirements include organic fertilizer fermentation tanks, compost turners, crushers, rotary drum granulators, screening machines, dryers, coolers, automatic packing machines, and belt conveyors. Therefore, the budget for setting up a granular organic fertilizer plant is $110,000 to $550,000.

Rotating drum granulation has the advantages of high granulation efficiency, uniform particles, and easy operation. It is suitable for a variety of fertilizer raw materials and can achieve continuous production.
