Simulation of a Laboratory Scale Ball Mill via Discrete

Modelling, Discrete Element Method, Milling Media, Planetary Ball Mill, Simulation 1 Introduction Simulation of various types of mills through DEM method provides the occasion to understand the dynamics inside the mill and also to develop the mill design and operation [1] In 1979, Cundall and Strack [2] were the first who proposedThe ball mills are often applied in mineral processing, they are eg an important part of the cement industry A key factor, which influences the milling process, is the granular flow of grinding media The flow determines: energy consumption, time of milling and capacity; thus there is a need to describe the phenomenon The discrete element method DEM is a computational method, which allows Simulation of the granular flow of grinding media

Simulation of the breakage of bonded agglomerates in a

The number of media initially loaded into the mill is represented by J, which is the fractional media filling, and is given by : (8) J = mass of media / media density mill volume × 10 06 Four levels of J are studied in this work, J = 03%, 15%, 40% and 107%, all at a constant grinding media size of d m = 254 mm, corresponding to 1, 5, 14A 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, ie DEM and combined DEMSPH First, a pilot scale ball mill with no lifter is simulated by both methods Combined DEM and SPH simulation of ball milling
