This is a granulator that compacts fine powder raw materials with low bulk density into flake form without using a binder, in order to obtain granulated products of the desired particle size.
By supplying pre-degassed raw materials horizontally within a vertically configured upper and lower roll, compared to a horizontally arranged roll type, there is less powder drop, and stable flakes can be obtained with high yield. 1. High bulk density products can be continuously and stably obtained, and low bulk density raw materials can also be compacted due to continuous pre-treatment with the hopper, horizontal screw, and degassing device. 2. High product yield is achieved through the selection of pre-degassing and breakers, resulting in high flake yield with minimal generation of fine powder. 3. The installation area and height per processing capacity are small, making it easy to scale up to larger machines. 4. As it is a dry process, intermediate processes such as wetting, mixing, and drying are unnecessary, allowing for reductions in both initial and running costs, easy condition changes with small sample sizes, and no need for binders. 5. The compression rolls are designed to accommodate a range from low to high loads, suitable for soft to hard flakes, and there are also cantilever roll types like the FR type that enhance disassembly and cleaning, offering a wide lineup. 6. Maintenance-free Our machines are highly durable, requiring only routine inspections even after continuous operation for 24 hours a day for one year, with no special maintenance needed (excluding consumables).

basic information
The characteristic of the granulation method using a roller compactor is that dry powdered raw materials are compacted into a plate shape, which is then crushed into granules. The fact that granules can be produced while remaining in dry powder form means that the drying process in the subsequent steps becomes unnecessary, significantly improving energy efficiency. This method is ideal for raw materials that react or change properties when moisture is added, as well as those that undergo changes during the drying process. Omitting the humidification, dehydration, and drying processes leads to substantial cost reductions. Additionally, it is optimal for raw materials for which one does not want to add a binder. Granulation Principle: The raw materials, which have been naturally degassed by their own weight, are quantitatively supplied to the screw feeder. By ensuring a consistent flow from the hopper to the screw, a uniform compacted material is created. As the raw material is drawn into the roll nip area from the screw, it is compressed and densified uniformly during the rolling process.
