A mathematical model has been developed to estimate the carry-over rate of particles in a closed-circuit grinding system and to predict its effect on the overall circulating load. This model along with the ball mill simulation model (BMSIMUL) has been used to analyse the performance of a raw mill circuit and a cement mill circuit of a 1 million tpy cement plant.

Ball (mathematics) - Wikipedia

In mathematics, a ball is the volume space bounded by a sphere; it is also called a solid sphere. It may be a closed ball (including the boundary points that constitute the sphere) or an open ball (excluding them).. These concepts are defined not only in three-dimensional Euclidean space but also for lower and higher dimensions, and for metric spaces in general.
