What Is a High Efficiency Disc Granulation Production Line

A high efficiency disc granulation production line is a specialized granulating system centered on the disc granulator, integrating raw material pretreatment, batching, mixing, granulation, drying, cooling, screening, and packaging. It is widely used in the granulation production of various fertilizers, relying on the inclined rotating disc structure and the combined action of centrifugal force, friction, and gravity to realize efficient granulation of powdery materials. Compared with other granulation production lines (such as drum granulation, extrusion granulation), the high efficiency disc granulation production line has the characteristics of high granulation rate, uniform particle size, low energy consumption, and flexible operation, which is suitable for small, medium, and large-scale fertilizer production enterprises, and has become the preferred fertilizer granulating solution in the industry.

Core Working Principle of High Efficiency Disc Granulation

The core of the high efficiency disc granulation production line lies in the scientific working principle of the disc granulator, which combines natural physical laws with engineering technology to achieve efficient and stable granulation. When powdery raw materials (such as organic fertilizer powder, compound fertilizer raw materials) enter the inclined rotating disc, they are affected by three forces: centrifugal force generated by the disc rotation, friction between the raw materials and the disc inner wall, and gravity. Under the combined action of these three forces, the powdery raw materials continuously slide, tumble, and agglomerate in the disc, gradually forming spherical particles like snowballs.

The high efficiency disc granulation production line realizes precise control of particle size and quality by adjusting three key parameters: disc inclination angle (stepless adjustment between 35°-65°), disc rotation speed (30-50 rpm), and water/binder spraying amount. The inclined angle of the disc determines the residence time of materials in the disc—too large an angle will lead to too short residence time and insufficient granulation; too small an angle will cause materials to accumulate and affect production efficiency. The rotation speed affects the centrifugal force, which directly determines the particle strength and sphericity. The water or binder spraying system ensures that the raw materials have appropriate humidity, promoting the agglomeration of particles and improving the granulation rate and particle quality.

Key Differences from Traditional Disc Granulation Lines

The high efficiency disc granulation production line is not a simple upgrade of the traditional disc granulation line, but a comprehensive optimization in technology, equipment, and control. The most obvious difference is the improvement of production efficiency—compared with the traditional disc granulation line, the high efficiency type adopts a frequency conversion speed regulation system and an optimized disc structure, which increases the granulation rate from 70%-80% to more than 93%, and the production capacity per unit time is increased by 30%-50%. Secondly, in terms of particle quality, the high efficiency production line is equipped with an intelligent monitoring system, which can real-time adjust the key parameters of granulation, ensuring that the particle sphericity reaches more than 85%, the particle size error is within ±0.5mm, and the particle strength is up to 25N, which is far higher than the traditional production line standard. In addition, the high efficiency disc granulation production line integrates energy-saving technology and environmental protection design, which reduces energy consumption by 30%-40% compared with the traditional type, and realizes closed production to avoid dust pollution, conforming to the global green production trend.

Core Equipment Configuration of High Efficiency Disc Granulation Production Line

A complete high efficiency disc granulation production line is composed of multiple functional equipment modules, and the reasonable matching of each module directly affects the overall efficiency, product quality, and operation stability of the production line. The core configuration is designed around the disc granulator, covering seven key systems, each of which undertakes a crucial link in the production process, ensuring the continuity and high efficiency of the whole production line. All equipment adopts wear-resistant, corrosion-resistant materials and advanced structural design to adapt to long-term high-load operation.

1. Raw Material Pretreatment System

The raw material pretreatment system is the foundation of high-efficiency granulation, which is used to process raw materials into a state suitable for granulation, ensuring the smooth progress of the subsequent granulation link. The core equipment includes a crusher, screening machine, and magnetic separator. The crusher is used to crush large-particle raw materials (such as crop straw, phosphate rock, livestock and poultry manure) into 2-5mm powdery particles, increasing the contact area of raw materials and promoting agglomeration. The screening machine is used to remove impurities such as stones, metals, and plastics in the raw materials, avoiding damage to subsequent equipment and ensuring the purity of the finished product. The magnetic separator further removes metal impurities in the raw materials, protecting the disc granulator and other core equipment. The pretreatment system adopts frequency conversion control, which can adjust the processing speed according to the raw material characteristics and production needs, ensuring the stability of the pretreatment effect.

2. Batching and Mixing System

The batching and mixing system is the key to ensuring the uniform nutrient content of granular fertilizer, especially for compound fertilizer production. The high efficiency disc granulation production line adopts an intelligent batching system, including a quantitative feeder, multi-bin electronic scale, and high-efficiency mixer. The quantitative feeder can accurately control the feeding amount of each raw material (such as nitrogen, phosphorus, potassium raw materials, organic matter, additives) according to the preset formula, with a batching accuracy of ±0.3%, ensuring the stability of product nutrient ratio. The multi-bin electronic scale realizes real-time weighing and data traceability of raw materials, which is convenient for production management and quality control. The high-efficiency mixer adopts a double-helix structure, which can fully mix various raw materials and binders in 5-8 minutes, with a mixing uniformity of more than 95%, avoiding local nutrient imbalance and laying a foundation for high-quality granulation.

3. Core Disc Granulator

The disc granulator is the core equipment of the entire production line, and its performance directly determines the granulation efficiency and product quality. The high-efficiency disc granulator adopts an optimized inclined turntable design, with a disc diameter of 1.2-6 meters (customizable according to production capacity), and the disc body is made of high-chromium alloy or stainless steel, with strong wear resistance and corrosion resistance, and the service life of key components exceeds 10,000 hours. The disc is equipped with a wear-resistant scraper and a non-stick lining, which can avoid material adhesion and reduce residue, reducing the workload of cleaning and maintenance. The disc inclination angle and rotation speed can be adjusted steplessly through the electric control system, which can flexibly adapt to different raw material characteristics (such as moisture content, viscosity) and particle size requirements (1-10mm adjustable). In addition, the disc granulator is equipped with a uniform feeding device and a precise water spraying system, which ensures that the raw materials are evenly distributed in the disc and the humidity is controlled accurately, further improving the granulation rate and particle uniformity.

4. Drying and Cooling System

After granulation, the granular fertilizer has high water content (20%-30%) and temperature, which need to be dried and cooled to meet the storage and transportation requirements. The high efficiency disc granulation production line adopts an energy-saving drying and cooling system, including a three-layer rotary dryer and a counter-flow cooler. The dryer uses waste heat recovery technology or low-cost heat sources (such as industrial waste heat) to dry the particles, which can quickly reduce the water content of the particles to below 15% (the standard storage water content) while ensuring that the nutrients of the fertilizer are not lost. The counter-flow cooler adopts natural wind or forced cooling technology, which can cool the dried particles to room temperature in a short time, avoiding moisture regain and caking during storage. The drying and cooling system is connected with a bag-type dust remover, which can collect the dust generated during the process, ensuring clean production and meeting environmental protection standards.

5. Screening and Return System

The screening and return system is used to ensure the uniformity of the finished product and improve the utilization rate of raw materials. The core equipment includes a grading screen and a return conveyor. The grading screen adopts a double-layer screen structure, which can separate unqualified particles (too large or too small) from the cooled particles. The unqualified particles are transported back to the crusher or disc granulator through the return conveyor for reprocessing, realizing the recycling of raw materials and reducing waste. The qualified particles enter the next packaging link. The grading screen adopts frequency conversion vibration technology, which has high screening efficiency and low noise, and can adjust the screen mesh according to the particle size requirements of the finished product, with strong flexibility.

6. Packaging System

The packaging system is the last link of the production line, which is used to package the qualified granular fertilizer into standard specifications for storage and transportation. The high efficiency disc granulation production line adopts a fully automatic packaging system, including an automatic weighing machine, a packaging machine, and a conveyor. The automatic weighing machine has high weighing accuracy (error ≤±0.1%), which can accurately control the weight of each bag of fertilizer. The packaging machine can realize automatic bagging, sealing, and labeling, with a packaging speed of 800-2000 bags per hour, which greatly improves packaging efficiency and reduces labor costs. The conveyor transports the packaged finished products to the warehouse for storage, realizing the automation of the whole packaging process. The packaging system can be adjusted according to different packaging specifications (25kg, 50kg, 1000kg), meeting the different needs of the market.

7. Intelligent Control System

The intelligent control system is the "brain" of the high efficiency disc granulation production line, which realizes the real-time monitoring, automatic adjustment, and centralized management of the whole production process. The system adopts a PLC control system and a touch screen operation interface, which is simple and easy to learn, and can realize one-key start and stop of the whole line. The intelligent monitoring system can collect key parameters such as disc rotation speed, inclination angle, raw material flow, drying temperature, and particle water content in real time, and display them on the touch screen. If there is an abnormal parameter, the system will automatically alarm and adjust, or remind the operator to handle it in time. Some advanced production lines also support remote control and data management through the cloud platform, which is convenient for operators to monitor the production status anytime and anywhere, reducing manual intervention and improving production management efficiency.

Complete Production Process of High Efficiency Disc Granulation Production Line

The high efficiency disc granulation production line adopts a streamlined and continuous production process, which integrates all links from raw material input to finished product delivery, with high production efficiency, stable product quality, and simple operation. The whole production process is divided into 8 key steps, forming a complete closed loop of production, which can be flexibly adjusted according to the type of fertilizer (organic, compound, inorganic) and production needs, ensuring the adaptability and flexibility of the production line.

Step 1: Raw Material Collection and Sorting

Collect raw materials according to the type of fertilizer to be produced: for organic fertilizer, the raw materials include livestock and poultry manure, crop straw, mushroom residue, kitchen waste, etc.; for compound fertilizer, the raw materials include urea, potassium chloride, phosphate rock, ammonium phosphate, etc.; for inorganic fertilizer, the raw materials include industrial by-products such as phosphogypsum and ammonium sulfate. Sort the collected raw materials to remove large impurities such as stones, metals, and plastics, so as to avoid affecting the operation of subsequent equipment and the quality of finished products. Classify the raw materials according to their types and properties, which is convenient for subsequent batching and pretreatment. For enterprises with their own industrial by-products, this step can also realize the recycling of waste, reducing raw material costs.

Step 2: Raw Material Pretreatment

Transport the sorted raw materials to the pretreatment system. First, crush the large-particle raw materials into 2-5mm powdery particles through a crusher, then screen them through a screening machine to remove small impurities and uncrushed large particles. For organic fertilizer raw materials, it is also necessary to carry out fermentation pretreatment (if not fermented in advance) to decompose the organic matter and kill pathogenic bacteria, insect eggs, and weed seeds, ensuring the safety and quality of the finished product. The pretreated raw materials are transported to the batching system for subsequent operation. The pretreatment step is crucial to improving the granulation efficiency and product quality, and can effectively avoid the problems of uneven granulation and low particle strength caused by unqualified raw materials.

Step 3: Intelligent Batching and Mixing

According to the preset fertilizer formula, the quantitative feeder in the batching system accurately feeds each raw material into the mixer. The multi-bin electronic scale real-time weighs the raw materials to ensure the accuracy of the batching ratio. The mixer fully mixes the various raw materials and appropriate binders (such as bentonite) for 5-8 minutes, making the nutrients and binders evenly distributed in the raw materials. The binder can improve the viscosity of the raw materials, promote the agglomeration of particles, and improve the granulation rate and particle strength. The mixed raw materials are transported to the disc granulator through the conveyor, ready for granulation. This step ensures the uniformity of the nutrient content of the finished product and lays a foundation for high-quality granulation.

Step 4: High-Efficiency Disc Granulation

The mixed raw materials are evenly fed into the inclined rotating disc of the disc granulator. Under the combined action of centrifugal force, friction, and gravity, the raw materials continuously slide and tumble in the disc. At the same time, the water spraying system sprays an appropriate amount of water or binder into the disc to adjust the humidity of the raw materials. With the rotation of the disc, the powdery raw materials gradually agglomerate into spherical particles. The operator or the intelligent control system adjusts the disc inclination angle, rotation speed, and water spraying amount in real time according to the granulation effect, ensuring that the particle size is uniform (1-10mm adjustable), the sphericity is more than 85%, and the granulation rate is more than 93%. The qualified particles formed in the disc overflow from the edge of the disc and are transported to the drying system through the conveyor.

Step 5: Drying Treatment

The granulated particles are transported to the three-layer rotary dryer. The dryer uses waste heat recovery technology or low-cost heat sources to heat the particles, and the hot air flows through the particles to take away the excess moisture. The drying temperature is strictly controlled between 80-120℃ to avoid nutrient loss caused by high temperature. The drying time is adjusted according to the initial water content of the particles, generally 15-30 minutes, until the water content of the particles is reduced to below 15%. The dried particles are transported to the cooling system through the conveyor. The drying system is equipped with a dust remover to collect the dust generated during the drying process, ensuring clean production and environmental protection compliance.

Step 6: Cooling Treatment

The dried particles have a high temperature (60-80℃), which need to be cooled to room temperature to avoid moisture regain and caking during storage. The particles are transported to the counter-flow cooler, and the cold air and the particles flow in the opposite direction, which can quickly cool the particles to room temperature. The cooling time is generally 10-20 minutes, and the cooled particles have good storage stability and are not easy to caking. The cooling system is also equipped with a dust remover to collect the dust generated during the cooling process, further ensuring clean production. After cooling, the particles are transported to the screening system.

Step 7: Screening and Return Processing

The cooled particles are transported to the grading screen for screening. The double-layer screen separates the particles into three grades: unqualified large particles, qualified particles, and unqualified small particles. The unqualified large particles are transported to the crusher for crushing, then returned to the mixer for reprocessing; the unqualified small particles are directly returned to the disc granulator for re-granulation. The qualified particles are transported to the packaging system. This step realizes the recycling of raw materials, reduces waste, and ensures that the particle size of the finished product is uniform, meeting the market requirements. The screening efficiency of the grading screen is high, which can keep up with the production rhythm of the whole line, ensuring the continuity of production.

Step 8: Automatic Packaging and Storage

The qualified particles are transported to the automatic packaging system. The automatic weighing machine accurately weighs the particles according to the preset packaging specifications (25kg, 50kg, etc.), then the packaging machine automatically bags and seals the particles, and the labeling machine pastes the product label (indicating product name, nutrient content, production date, shelf life, etc.). The packaged finished products are transported to the warehouse through the conveyor for storage. The warehouse should be kept dry, ventilated, and moisture-proof to avoid the finished products being affected by moisture and caking. For large-scale production enterprises, the storage link can be equipped with an intelligent warehouse management system to realize real-time monitoring of inventory and improve storage efficiency. This step completes the whole production process of the high efficiency disc granulation production line, which is efficient, standardized, and environmentally friendly.
