Modeling ball impact on the wet mill liners and its ...

2014-6-1 · 1. Introduction. In a horizontal ball mill, particle size reduction is achieved by rubbing or impacting heavy masses in the rotating cylinder. Those masses, consisting of ore particles and grinding balls, either cascade down the surface or fall (cataract) through the free space onto the material or, under certain circumstances, onto the mill liners.

Prediction of cutting forces in ball-end milling of 2.5D C ...

2016-6-1 · Conclusions. An alternative cutting force model for ball-end milling of 2.5D C/C composite materials is proposed. First, the chip formation area is divided into three deformation zones. The cutting forces for 0° and 90° fiber orientations in three deformation zones are calculated individually.
