12-15TPH Rotary Drum Granulation Production Line
The comprehensive set of equipment for the 8-12TPH organic fertilizer granule production line primarily includes organic fertilizer fermentation tanks, compost turners, organic fertilizer crushers, rotary drum granulators, rotary drum dryers and coolers, drum screening machines, automatic packaging machines, etc.
Raw materials for organic fertilizer production, such as livestock and poultry manure, domestic garbage, dead branches, leaves, biogas residue, waste bacteria, etc., undergo semi-(high) wet fermentation in the fermentation tank. Following fermentation, the material is crushed by the crusher. Nitrogen, phosphorus, potassium, and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) are then added to ensure that the mineral elements meet specified standards. Subsequently, the material is mixed using a mixer, and the particles enter the granulation mechanism. After emerging, the particles undergo drying. Qualified products are screened by the screening machine and proceed to packaging, while unqualified products are returned to the granulator for further granulation.

12-15TPH organic fertilizer granule production line process:
The detailed presentation of the process flow and associated common equipment is outlined below. Feel free to get in touch with us, and we will personally guide you through the equipment composition and construction planning scheme of an organic fertilizer production line capable of producing 120,000 to 150,000 tons per hour. Additionally, we can offer an organic fertilizer production formula tailored to meet your specific requirements.
The first step in making organic fertilizer is to collect various organic fertilizer raw materials. Including agricultural waste, livestock and poultry manure, plant straw, etc. These natural resources are regarded as valuable sources of nutrients, and through proper collection and processing, they can be converted into efficient organic fertilizers.
Following preliminary treatment, the organic raw materials collected are transported to the aerobic fermentation pile. Within this aerobic fermentation setting, microorganisms are encouraged to metabolize organic matter by ensuring adequate oxygen, regulating humidity, and maintaining an optimal carbon-nitrogen ratio. Our range of fermentation equipment comprises two types: organic fertilizer fermentation tanks and turners. The specific differences are outlined as follows:
Organic fertilizer fermentation tanks typically come in sealed containers equipped with suitable ventilation systems to guarantee a sufficient oxygen supply and facilitate aerobic fermentation. Following proper proportioning, ventilation, humidity control, and other essential conditions, organic raw materials are thoroughly exposed to oxygen, undergoing fermentation through the activity of microorganisms. The compost turner is responsible for turning and stirring the fermented organic materials, enhancing the uniformity and ventilation of the fermenting substances.
The organic fertilizer crusher is a specialized machine for breaking down organic raw materials into finely crushed particles during organic fertilizer production. This stage follows aerobic fermentation, aiming for the optimal particle size for subsequent granulation. Organic materials, typically loose after fermentation, are further crushed for enhanced granulation. The crusher employs a scientific and efficient mechanism to ensure uniform and stable particle texture, contributing to high-quality organic granular fertilizer meeting standards. It plays a pivotal role in improving granulation effects and overall efficiency in the organic fertilizer production process.
After crushing, the mixer ensures a homogeneous blend through precise stirring and turning. The organic fertilizer mixer prevents clumping in the fermentation pile, crucial for high-density and uneven-humidity situations. Its efficiency maintains material uniformity, enhancing overall organic fertilizer quality. The mixer’s role in achieving a consistent, well-mixed composition is key to subsequent stages in the production process.
Granulation stands as a pivotal stage in the organic fertilizer production process. Following aerobic fermentation and material crushing, the organic raw materials proceed to the rotary drum granulator for the granulation process. In this phase, the raw materials undergo continuous high-speed rotation within the drum, gradually forming granules. Maintaining proper humidity and temperature during granulation is essential to ensure the stability and formation of granules. Typically, a specific amount of auxiliary wetting agent is introduced inside the rotary drum granulator to enhance adhesion between raw materials and facilitate granule formation.
Ultimately, the granulator operation successfully transforms organic raw materials into uniform and stable organic fertilizer particles. These granules exhibit favorable particle size and mechanical strength, facilitating convenient storage, transportation, and application. This convenience contributes to the widespread utilization of organic fertilizers.
To enter the dryer, the material must undergo a drying process. As the dryer rotates, a set of internal fins lines the inner wall, lifting the material. Once the material reaches a specific height, the fins facilitate its descent, causing it to fall back to the bottom of the dryer. During this descent, the material passes through the hot gas stream. The system incorporates independent air heating systems and centralized waste discharge, leading to efficiency gains and cost savings in terms of energy consumption.
The organic fertilizer, having undergone the previous steps of fermentation and granulation, is directed to the Rotary Drum Cooler for the cooling phase. The Rotary Drum Cooler plays a pivotal role in lowering the temperature of the freshly granulated fertilizer, preventing the risk of moisture absorption and caking during subsequent storage and transportation.
The Rotary Drum Cooler operates by utilizing a rotating drum, through which cool air is passed. As the granules move through the drum, the cool air extracts the heat generated during the granulation process, effectively reducing the temperature of the organic fertilizer. This cooling process not only enhances the stability and shelf life of the fertilizer but also helps retain the nutrients in their optimal form.
Screening serves the purpose of eliminating fine particles or clusters among particles, guaranteeing the consistency and quality of the ultimate product. Utilizing vibrating screen surfaces, the rotary screen machine classifies particles into various levels based on size, efficiently eliminating particles that do not meet the specified requirements.
Equipped with user-friendly controls, the fertilizer packing machine allows for customization of packaging specifications, accommodating varying bag sizes and weights. The automated operation not only enhances efficiency but also reduces the risk of errors, contributing to the overall quality of the packaged organic fertilizer.
