In today's constantly developing granulation technology, the roller extrusion granulator, with its advanced equipment principle, leads granulation technology towards a new direction.
The operation of the roller extrusion granulator is based on a simple and efficient principle. After the equipment is started, the power source drives two parallel rollers to rotate synchronously in opposite directions. The material is uniformly fed into the gap between the two rollers through the feeding system. As the rolling mill rotates, the material gradually enters the high-pressure extrusion zone formed by the two rollers.
In the extrusion zone, the extrusion force exerted by the rolling mill on the material is the core driving force for granulation. This squeezing force can overcome the interaction force between material particles, making them tightly bonded. The specially designed concave mold on the surface of the rolling mill is the key "mold" for particle forming. When the material is pressed into the concave mold under the squeezing force, it is given the shape of the concave mold, thus forming continuous strip-shaped particles. Subsequently, the cutting device divides the strip-shaped particles into individual finished particles according to the set length.
This principle has brought various innovative developments to granulation technology. On the one hand, in the increasingly strict environmental requirements, the feature of roller extrusion granulators that do not require the addition of binders is particularly prominent. This not only reduces the potential environmental pollution caused by the use of adhesives, but also lowers production costs, in line with the concept of green production. The production of many environmentally friendly products, such as organic fertilizers and biopharmaceutical raw materials, can leverage this advantage to achieve sustainable development.
On the other hand, there has been a new breakthrough in particle accuracy control for roller extrusion granulators. Through high-precision machining and advanced control systems, it is possible to precisely design and manufacture concave molds on rolling rolls, thereby achieving precise control over particle shape, size, and density. This makes the quality of the produced granular products more stable and uniform, meeting the strict requirements of the high-end market for product quality.
In addition, the principle of the roller extrusion granulator also provides convenience for the automation upgrade of the equipment. Modern roll extrusion granulators are equipped with advanced sensors and intelligent control systems, which can monitor and adjust the operating parameters of the equipment in real time, such as feed speed, roll pressure, cutting length, etc. This not only improves production efficiency, but also reduces manual intervention and lowers labor intensity.
The roller extrusion granulator, with its unique equipment principle, has opened up new paths for granulation technology in environmental protection, precision control, and automation, leading granulation technology towards more efficient, accurate, and green directions, and providing strong support for the upgrading and innovation of many related industries.
