background

Pulverization and physical separation technology is an important unit operation in environmental cleanup and resource recycling, but it is difficult to select design and operation conditions in a unified method due to the multiple behavior types of powders.

summary

It is possible to use a certain type of powder simulation, the Discrete Element Method (DEM) to ascertain in detail, the positions and speeds of each particle in the apparatus, and collision energies between particles and between particles and the walls.

application/development

It is possible to apply this technique to various kinds of unit operations on particles.

predominance

By introducing a new model that accelerates the calculation of collisions between particles, we have not only facilitated analysis on an actual equipment scale, but also developed simulation tools that incorporate particle fracture models specified to pulverization phenomena.
