Abstract. Today the modeling of the process dynamics and the complex twophase flows in mills still remain a challenging task. In this study the dynamic comminution process in a fluidized bed opposed jet mill is investigated. For this purpose, welldefined model glass beads were ground in a labscale mill. The particle size distributions (PSDs ...

The grinding time of the LBM was set by reducing the total RT taken by the blend to get ground in the BBM, since the BBM produces very fine particles for 250% circulating load. The TRT taken in the BBM for the blend sample was considered as reference grinding time for the LBM (ball mill refers to as LBM of size 500 mm × 1000 mm with liners).

For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.

Introduction. The production of fine particles in the lower micron range by dry grinding processes demands large amounts of energy. For instance, the cement industry alone consumes approximately 1215% of the world's total industrial energy, whereby the fine finish grinding of the cementitious products accounts for about 30% of the overall energy consumption (Madlool, 2011).
