The extrusion organic fertilizer granulator in the NPK fertilizer production line is an efficient and widely applicable equipment, mainly used to extrude organic materials and other nutrients into granules, especially suitable for the production of NPK (nitrogen phosphorus potassium) compound fertilizers. The following are some characteristics and working principles of the squeeze organic fertilizer granulator:
characteristic
High pressure: Using high-strength screws and templates, it can work under high pressure and is suitable for handling various difficult to compress materials, including organic materials with high moisture and fiber content.
Widely applicable: It can not only be used for pure organic fertilizers, but also mixed with other inorganic fertilizers for granulation, with strong adaptability.
Particle uniformity: The particles produced by the extrusion granulation mechanism have consistent size and beautiful appearance, which is conducive to the uniform application of fertilizers and mechanical sowing.
Wear resistant and corrosion-resistant: Stainless steel or special alloy materials are usually used for the parts in contact with materials, which can withstand long-term wear and corrosion and extend the service life of equipment.
Energy saving and environmental protection: Compared with other granulation methods, extrusion granulation consumes less energy, produces less dust, and has lower noise, which is more in line with the environmental protection requirements of modern industrial production.
Automated control: Modern extrusion granulators are equipped with automatic control systems that can accurately adjust parameters such as temperature and pressure, achieving intelligent operations.
working principle
The extrusion granulator mainly consists of feeding hopper, screw propulsion mechanism, template, cutter, and transmission system. The material enters through the feeding port and is pushed to the front of the template by the screw. It passes through the template hole under high pressure and is instantly cut into particles of a specified length by the cutting blade on the outside of the mold hole. Then, it enters the cooling or drying equipment for subsequent processing.
During the extrusion process, the pressure and shear forces on the material can cause its temperature to rise, which helps to rearrange and bond the molecules between the materials, thereby forming a stable particle structure. After the extrusion process is completed, the particles need to be cooled and solidified to prevent softening or damage during transportation and storage.
Squeezing granulator is an indispensable part of NPK fertilizer production line. Through optimized design and reasonable operation, the quality and production efficiency of fertilizers can be greatly improved, meeting the demand for high-quality fertilizers in agricultural production.
