The compound fertilizer granulation production line is a kind of equipment widely used in the production of compound fertilizers.
Characteristics
The compound fertilizer rotary drum granulation production line is a widely used process equipment in the fertilizer production field. Its core features are reflected in multiple aspects such as process adaptability, production stability, product quality control, and overall economy. The specific points are as follows:
1. Strong process adaptability, wide raw material compatibility range
The rotary drum granulation process has a high compatibility with the physical properties and chemical composition of raw materials. It can handle basic fertilizers such as urea, ammonium chloride, monoammonium phosphate, and potassium chloride, as well as functional raw materials such as organic fertilizers, humic acid, and trace elements. Whether it is solid powder, granular materials, or semi-solid materials with certain humidity, they can be included in the production process through reasonable proportioning and pre-treatment, especially suitable for the production of flexible multi-functional compound fertilizers to meet the individual needs of different crops and soils.
2. Continuous and stable production, flexible scale adjustment
The production line uses the rotary drum as the core granulation equipment. Through the continuous rolling and adhesion of materials in the drum, granulation is achieved. Combined with the front-end raw material metering and mixing system and the rear-end drying, cooling, and screening processes, a closed-loop continuous production process can be formed. The production capacity of a single production line can be flexibly designed according to demand, ranging from small-scale production of tens of thousands of tons per year to large-scale production of several hundred thousand tons per year. During the production process, parameter control is convenient, and stable output can be maintained for a long time.
3. Controllable product quality, excellent particle performance
The compound fertilizer particles produced by the rotary drum granulation have the following advantages: First, the particle uniformity is high. By adjusting the rotational speed, inclination angle, and moisture content of the materials, the particle size can be precisely controlled (usually in the range of 2 – 4.75mm), with a qualified rate of over 90%. Second, the particle strength is good. The particles formed by rolling and compaction have a dense structure and strong resistance to crushing, and are less likely to clog or powderize during storage, transportation, and application. Third, the nutrient distribution is uniform. The raw materials are fully mixed during the mixing stage, and the nutrients are further encapsulated during the granulation process, ensuring the consistency of nutrient content in each fertilizer particle.
4. Lower energy consumption and cost, superior overall economy
Compared with spray granulation, high-tower granulation, etc., the rotary drum granulation production line has lower equipment investment costs, especially suitable for small and medium-sized enterprises with initial investment. In terms of energy consumption, the main energy consumption is concentrated in the drying process. By optimizing the hot air circulation system and heat recovery devices, the unit product energy consumption can be effectively reduced. In addition, the production line has relatively loose requirements for raw material pre-treatment and does not require complex melting or atomization equipment, further reducing production and maintenance costs.
5. Simple operation and maintenance, high equipment reliability
The rotary drum granulation equipment has a relatively simple structure, and the core component of the drum uses wear-resistant linings (such as rubber linings, cast stone linings). The service life is long, and the failure rate is low. The operation of the production line can be achieved through a PLC control system, and operators can master parameter setting and daily monitoring through simple training. The maintenance focuses on key components such as the drum transmission system and screening equipment, with a standardized maintenance process and convenient spare parts replacement, which can effectively reduce downtime.
6. Optimized environmental performance, meeting green production requirements
Modern rotary drum granulation production lines integrate dust collection devices (such as pulse dust collectors) and tail gas purification systems to effectively treat dust and exhaust gas generated during production, reducing pollutant emissions. At the same time, the water recycling system of the production line can achieve water reuse, reducing water consumption, and meeting the green and low-carbon development trend of the fertilizer industry.
7. Upgrade of automation level, improvement of production accuracy With the application of intelligent manufacturing technology, the drum granulation production line can be equipped with online detection equipment (such as near-infrared analyzers and particle size detectors), which can monitor key indicators such as raw material ratios and particle quality in real time. Through an automatic feedback system, it can adjust the measurement and granulation parameters to achieve precise control throughout the process, further improving product stability and qualification rate.
In summary, the drum granulation production line for compound fertilizers, with its characteristics of strong adaptability, stable and efficient operation, and controllable costs, has become the mainstream process choice for compound fertilizer production. Especially in scenarios with multiple formulations and medium-low production capacity requirements, it demonstrates significant advantages and provides strong support for the large-scale and refined development of the fertilizer industry.
Application fields
The compound fertilizer drum granulation production line, with its strong continuous production capacity, stable particle formation quality, and wide adaptability to raw materials, is widely used in agricultural and related fields. It mainly covers the following scenarios:
1. In the field of large-scale crop cultivation, such as wheat, corn, rice, and soybeans, the drum granulation production line plays a core role. These crops have a high demand for fertilizers and require balanced nutrients. The production line can adjust the ratios of nitrogen, phosphorus, potassium, and trace elements to produce general or specialized compound fertilizers that meet the needs of different growth stages of the crops. For example, for the high potassium requirement during the jointing stage of corn, a high-kaliometer formula granular fertilizer can be customized; in rice cultivation, a fertilizer containing silicon and zinc can be produced to enhance the crop’s resistance to lodging and yield. Its stable production capacity (up to tens to hundreds of tons per production line per day) can meet the fertilization needs of large-scale farmland.
2. In the field of economic crop cultivation, such as vegetables, fruit trees, and flowers, the drum granulation production line can be targeted to develop specialized fertilizer products. In vegetable cultivation, the compound fertilizer for tomato and cucumber (capable of茄果类 crops) needs to pay attention to the balance of nitrogen， phosphorus， potassium， and calcium and magnesium supplementation. The production line can control the hardness and slow-release performance of the particles to reduce the frequency of topdressing； in fruit tree cultivation， for the long-fertilizer-demanding characteristics of apples and citrus， a slow-release compound fertilizer can be produced， achieving slow nutrient release through the coating process in the drum， avoiding root burn and nutrient loss； in flower cultivation， a low-salt formula granular fertilizer can be produced to meet the mild nutrient requirements of potted flowers.
3. In the fields of forestry and ecological greening， the drum granulation production line produced compound fertilizers can provide long-term nutrient support. In fast-growing forests (such as poplar and eucalyptus) planting， high-nitrogen and high-phosphorus formula granular fertilizers can promote rapid tree growth； for economic forests (such as walnut and chestnut)， attention should be paid to the supply of nutrients during the flowering and fruiting periods， and the production line can produce compound granular fertilizers containing humic acid to improve fruit quality； in urban greening， for the growth characteristics of lawns and street trees， low-salt formula granular fertilizers can be produced to meet the mild nutrient requirements of green plants， ensuring uniform growth after fertilization and reducing maintenance costs.
4. In the fields of soil improvement and specialty cultivation， the drum granulation production line can produce functional compound fertilizers. By adding conditioning agents such as desulfurized gypsum and humic acid， the conditioning components and nutrient particles can be combined to supplement nutrient supply while improving soil structure； in facility agriculture (such as greenhouse)， for the soil compaction problem caused by consecutive cultivation， compound granular fertilizers containing biological agents can be produced， using the gentle process of drum granulation to protect the activity of the agents； in addition， in specialty cultivation fields such as Chinese medicinal herbs and tea， compound fertilizers in line with organic farming standards can be produced， through natural raw material ratio and granulation technology， meeting the fertilizer requirements of green agriculture.
5. In large-scale agriculture and modern agricultural parks， modern agricultural parks and planting cooperatives， which rely on the drum granulation production line to achieve self-sufficiency or customized supply of fertilizers. The production line can be combined with soil testing and formula fertilization technology， adjusting the formula in real time based on the soil test data， and producing “one field， one strategy” specialized fertilizers； at the same time， its automatic control system (such as the intelligent regulation of batching， granulation， and drying processes) can ensure stable fertilizer quality， adapt to the spreading requirements of large-scale fertilizing machinery， and enhance the intensification level of agricultural production.
In summary， the drum granulation production line of compound fertilizers through its flexible formula adjustment ability， stable particle quality， and large-scale production efficiency becomes a key link connecting fertilizer production and various cultivation scenarios， supporting the precise fertilization and efficient development of modern agriculture.
