The roller extrusion granulator, with its unique equipment principle, has been widely used in multiple industries, achieving a perfect combination of principle and application.
From a theoretical perspective, the core of a roller extrusion granulator is to utilize the extrusion force generated by two opposing rotating rollers to achieve material shaping. The motor provides power to the rollers, causing them to rotate at a stable speed. The material enters from the feeding port and is evenly distributed in the gap between the two rollers under the action of gravity and the feeding device.
As the rolling mill rotates, the material is gradually brought into the extrusion zone. In this area, the squeezing force exerted by the two rollers on the material can reach several tons or even tens of tons. Under such strong pressure, the binding force between material particles is broken, rearranged and combined, and tightly bonded to each other. The concave mold on the surface of the rolling mill plays a crucial role at this time, as the material is pressed into the concave mold to obtain a specific shape.
This unique principle enables the roller extrusion granulator to demonstrate strong application advantages in multiple fields. In the fertilizer production industry, it can directly squeeze various powdered fertilizer raw materials into granules. Due to the absence of additional binders, it can maximize the retention of nutrients in fertilizers and improve their effectiveness. Moreover, by adjusting the shape and size of the concave mold of the rolling mill, different specifications of fertilizer particles can be produced to meet the needs of different crops and fertilization methods.
In the chemical industry, roller extrusion granulators can be used to manufacture various chemical product granules. For some chemical raw materials that require high purity and do not allow impurities to be mixed in, the characteristic of this granulator that does not require a binder is particularly important. It can ensure that the quality and performance of the product are not affected by additives, while efficiently converting powdered raw materials into granular products that are easy to store, transport, and use.
In the feed industry, roller extrusion granulators also play an important role. It can squeeze various feed materials into pellet feed suitable for different farmed animals. By adjusting the size and hardness of particles, different animals' feeding habits and digestive needs can be met. Moreover, the extrusion granulation process can to some extent kill harmful microorganisms in the raw materials, improving the safety and stability of the feed.
By virtue of its scientific equipment principle, the roller extrusion granulator has found broad application space in multiple industries such as fertilizers, chemicals, and feed, achieving a perfect transformation from principle to practical application and providing strong technical support for the development of various industries.
