The technical group of granulation aims at enlightening wide range industrial fields related to granulation technology. For that purpose the group surveys excellent technologies of granulation used in various fields and introduces the information obtained from the survey to people concerned. The group intends to bring new development /innovation to traditional industrial areas across fields. We hope that a standard know-how in one field will inspire innovation in another field. We know that many established methods have come from human sensitive feelings and experience. We should learn and refer such knowledge to step-up our technology.
Current level of technology, trend and activities in future
Granulation is a unit operation for handling powders and creating functional powders. Powder handling includes segregation, compaction, flow, resolution, disintegration, transport, maintenance etc. Granulation methods and operation conditions are of wide variety, and the process of granulation should be optimized depending on the methods. It is demanded to develop hybrid powders and particles which express intelligent and multifunctional performance. For that purpose, soft matters such as nanoparticles, high molecular, liquid crystal, colloid, biomolecule etc. are used. To meet such various requests, it is important to define and control the speed of agglomerate formation. On the other hand, continuous operation is also demanded to improve productivity. This group held a discussion meeting of the continuous operation system of granulation in 2016. Continuous operation is realizable in various granulation methods, and the following techniques are being improved; monitoring technique of the agglomerate formation process, technique to prepare for granulation (mixing), inspecting technique of properties of agglomerated particles and recirculation technique to achieve uniformity. The most important assignment is to construct the mechanism to predict the process of agglomerate formation. Nowadays it is becoming possible to predict particle motion by DEM simulation. There is a demand to develop granulation simulation which is used for monitoring the process of agglomerate growth. This group will provide information on current movement and technology level of this area through discussion meetings.
