Understanding fine ore breakage in a laboratory scale

2011-2-1  The feed (ore) size distribution used was also chosen to match the feed that would typically be used in such a ball mill test. It is relatively fine with a top size of 2.8 mm.This distribution has been truncated at 1.18 mm to keep the simulation size under 1 million particles in order to make the computational duration manageable.The effect of this cut off size will be assessed in future work.

Friction and wear of liner and grinding ball in iron ore ...

2017-11-1  In this study, the ball cratering method is used to analyze the friction behavior and the wear mechanism of the liner in the iron ore ball mill under different working conditions. And as stated in the literature [30] , it is very important to choose the appropriate contact parameters in simulations using the discrete element method (DEM).

Optimization of Solids Concentration in Iron Ore Ball ...

Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore ...

Understanding fine ore breakage in a laboratory scale

For SAG mills, a large fraction of the feed material can now be accurately represented in DEM models. However, for other mill types with much finer feed materials, such as the second chamber of a cement ball mill, the vast numbers of feed particles makes their explicit inclusion in the models prohibitive.
