Configuring equipment for a compound fertilizer production line is a systematic project that requires comprehensive consideration of multiple aspects. Here are some suggestions for configuring equipment for compound fertilizer production lines:
 
1. Raw material processing equipment
Crusher: used to crush large pieces of raw materials for subsequent processing. Select the appropriate model based on the hardness and particle size requirements of the raw materials.
Screening machine: Screen the crushed raw materials to separate the required particle size and remove impurities. The screening machine has the advantages of simple structure, high screening efficiency, and easy operation.
 
2. Ingredient equipment
Automatic batching system: composed of storage hopper, feeding mechanism, measuring device, control system, etc., it can automatically complete the batching work of raw materials according to the preset formula, with high accuracy and efficiency, reducing manual errors and improving the stability of product quality.
Belt conveyor: responsible for conveying various raw materials to the corresponding equipment, with the characteristics of large conveying capacity, long conveying distance, simple structure, and easy maintenance. Suitable length and width can be selected according to the layout and process requirements of the production line.
 
3. Hybrid equipment
Horizontal mixer: a common mixing equipment that thoroughly mixes various raw materials through the rotation of the stirring blade, suitable for mixing powdered and granular materials. Its advantages are good mixing effect, high production efficiency, and convenient unloading.
Double helix mixer: Using the rotation of two helical shafts, the material is pushed from both ends to the middle and mixed at the same time, resulting in a more uniform mixing effect, especially suitable for the production of compound fertilizers that require high mixing uniformity.
 
4. Granulation equipment
Disc granulator: By rotating the disc and spraying water, the material gradually forms particles on the disc. It has the advantages of simple structure, stable operation, and high balling rate, but its production capacity is relatively small, suitable for small and medium-sized compound fertilizer production.
Drum granulator: The material is continuously rolled and squeezed inside the drum to form particles, with high production efficiency and particle strength, but strict requirements for the particle size and humidity of the raw materials.
Squeezing granulator: using dry extrusion technology, it does not require water and can directly extrude powdered materials into particles. It has the advantages of energy saving, environmental protection, and no discharge of three wastes, and the produced particles have regular shapes and uniform sizes.
 
5. Drying equipment
Rotary dryer: By fully contacting hot air with wet particles, the moisture in the particles is evaporated to achieve the purpose of drying. The drying effect of this device is good and the output is large.
 

6. Cooling equipment
Rotary cooler: Ventilating and cooling the dried particles can quickly reduce their temperature and improve production efficiency.
 
7. Screening equipment
Drum screening machine: By rotating the drum, particles are screened on the screen surface, and those that meet the requirements are screened out, while those that do not meet the requirements are returned for reprocessing. The drum screen has high screening efficiency, stable operation, and easy maintenance.
 
8. Packaging equipment
Automatic quantitative packaging machine: It can automatically pack compound fertilizer into packaging bags according to the preset weight and seal them. It has high precision, fast speed, and easy operation, which can greatly improve production efficiency and packaging quality.
 
9. Control system
Automated control system: using advanced control technologies such as PLC programmable controllers and touch screens, the equipment of the entire production line is centrally controlled and managed to achieve automated production, improve production efficiency and product quality stability, and reduce manual intervention and labor intensity.
Monitoring system: equipped with various sensors and monitoring instruments, real-time monitoring of temperature, pressure, flow rate, speed and other parameters during the production process, ensuring the safe and stable operation of the production process.
 
In summary, the configuration of compound fertilizer production line equipment requires comprehensive consideration of multiple factors to ensure the efficient, stable, and environmentally friendly operation of the production line. Meanwhile, with the continuous advancement of technology and improvement of production processes, the selection and configuration of equipment for compound fertilizer production lines will also be continuously optimized and perfected.
