In the field of fertilizer production, the roller extrusion granulator has become an efficient choice for many manufacturers to process fertilizers due to its unique advantages.
The working process of the roller extrusion granulator is rigorous and orderly. The first stage is the preparation of raw materials. Fertilizer raw materials that have undergone early fermentation, crushing, and other treatments need to have appropriate humidity and particle size. The humidity is generally controlled within a specific range. If it is too dry, it will cause difficulty in forming particles, while if it is too wet, it can easily cause material adhesion to the equipment. The particle size also needs to be uniform to ensure even force distribution during the granulation process.
When the raw materials are ready, the critical granulation process begins. The roller squeezing granulator is mainly composed of two rollers that rotate in opposite directions, and the surface of the rollers is engraved with grooves of specific shapes and sizes. The raw materials are transported between two rollers, and as the rollers rotate, they are subjected to strong squeezing force. Under the squeezing force, the raw material is filled into the grooves on the surface of the roller, gradually forming columnar particles that conform to the shape of the grooves.
After being extruded from the roller, these columnar particles will pass through a cutting device. The cutting blade cuts continuous cylindrical particles according to the preset length, forming uniformly sized fertilizer particles. The entire granulation process does not require the addition of additional binders, which not only reduces production costs, but also maximizes the retention of the original nutrients of the fertilizer, ensuring the quality and efficiency of the fertilizer.
The roller extrusion granulator has many advantages. Its structure is relatively simple, and it is easy to operate and maintain. During the production process, the equipment operates stably and has high production efficiency, which can meet the needs of large-scale fertilizer production. Moreover, by replacing rollers with different groove shapes and sizes, various shapes and specifications of fertilizer particles can be produced to meet the diverse needs of the market.
In addition, the roller extrusion granulator also performs well in environmental protection. Due to the absence of the need to add binders, the use of chemicals is reduced, and potential pollution to the environment is minimized. At the same time, the equipment has low noise and dust during operation, creating a good working environment for the production workshop.
The roller extrusion granulator plays an important role in the field of fertilizer processing due to its efficient processing method, stable performance, and environmentally friendly characteristics, providing high-quality fertilizer guarantee for agricultural production.
