Numerical simulation of particle breakage and grinding

Research output: Contribution to journalReview articlepeer-review


Grinding is one of the most basic and important operations of powder processing. Grinding has been carried out all over the world for a long time. However, the grinding mechanism has not been elucidated scientifically. Computer simulation have a possibility to be a useful tool to clarify the grinding mechanism. In this review, new simulation methods for particle breakage were introduced, and the advantage of each method was discussed. Prediction of grinding results based on the impact energy has an advantage of calculation load, however, it is difficult to analyze the grinding process. On the other hand, direct simulation of particle breakage can analyze the grinding process. It is necessary to choose an appropriate method according to the purpose.
