The technical group of mixing, kneading and forming plans and conducts a factory tour and a lecture under the slogan of “taking a lesson from the past” and “state-of-the-art” concerning the subjects that the group is involved with. In addition, the group aims at establishing the evaluation method of each state of mixture, kneading, and molding/casting in a pharmaceuticals and ceramics manufacturing where mixing and molding/casting are key processes. The group proceeds with the investigation to the goal of standardization in “evaluation method of kneading state” by organizing a subcommittee
Current level of technology, trend and activities in future
- Homogeneous mixing/kneading technology: Several kinds of mixers and kneaders having multiple functions have been developed correspondingly to a diversity of powder mixtures and kneaded mixtures. Mixers and kneaders have been efficiently designed based on a numerical simulation to obtain homogeneous mixing/kneading conditions. Techniques of mixing/kneading for cohesive powders, small amount of additives, and so on are required.
- Fine mixing/kneading technology in nano scale: For industrial applications of nanomaterials such as nanoperticles or CNTs etc., a homogeneous dispersion of nanoparticles into a matrix and a binding between nanoparticles and bulk materials are essential. In order to disperse nanoparticles and combine with other materials, powders should be treated by not only mechanical techniques such as kneading, but also chemical/interfacial chemical processes. And control technologies of contamination due to mixing/kneading are also important for fine mixing/kneading in nano scale.
- Well controlled molding/casting: In powder molding/casting, a surface modification of raw particles and a composing of the particles play important roles for preventing tableting disorder. And molding/casting restraining morphological changes has been desired.
- Standardization for characterization of mixing, kneading and casting: In future, qualities of casting products should be estimated based on the properties of raw powders or status of kneaded mixture. The appropriate techniques to characterize the mixing/kneading properties should be developed. Those characterization methods should be standardized because the methods are very useful in the designs of mixer/kneader and mixing/kneading process.
