ball mill circuit operation simulation

Combined DEM and SPH simulation of ball milling
A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them and therefore reduce their consuming power In this work the milling operation of ball mills is investigated using two methods i.e DEM and combined DEM SPH First a pilot scale ball mill with no lifter is simulated by both methods.

Modelling and simulation of ball mill wearScienceDirect
1 Introduction Ball mills play an important role in the mineral processing industry of today Yet as such they are difficult to study given the closed nature of the operation Once operating the ball mill becomes a black box where only input and output materials can be observed as well as the power draw of the grinding system.
