Granulation

About us

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

The granulation technology is increasingly important to control of particle structure and addition of particle function. Not only hard solid but also soft matter materials such polymer, liquid crystal, colloid, biomolecule are included in the category of functional materials. These soft matter materials are expected to be new composite materials by handling super-fine particles.
Improvement of the powder handling process is needed for powders showing poor flow-ability. Such powders should be uniformly dispersed and mixed in the pre-treatment before they are provided as powders of multi-component materials.
On the other hand it is very important to clarify powder structure, dynamic properties and phenomena at high- level liquid saturate condition,because the form of the solid/liquid mixture which is regarded as wet powder will be shifted from the pendular to the funicular state.
For further study, it is advisable to develop new modeling methods of analysis about powder agglomeration and kinetic phenomena of liquid binding. Numerical simulation is indispensable to making a visual understanding of validation of granule structure and function.
