We propose a new model for the prediction of the specific grinding energy, which proved to approach very well the values calculated with the help of the Denver slide rule. The proposed model, combined with a model giving the ball-mill power draw, is used for the ball-mill scale up. Comparisons with the Bond procedure.

We propose a new model for the prediction of the specific grinding energy, which proved to approach very well the values calculated with the help of the Denver slide rule. The proposed model, combined with a model giving the ball-mill power draw, is used for the ball-mill scale up. Comparisons with the Bond procedure.

This facilitates an understanding of the radial motion of the charge, estimation of power draw and of liner wear, but it cannot provide information about axial transport within the mill. In this paper, we examine . Early work on ball mills by Mishra and Rajamani [1,2] has been followed by Cleary [3,4]. Similarly SAG mills were.

The parameters include the balls' real-time kinetic energy, the friction energy consumption, and the mill's total work. Meanwhile, a method of balanced adjacent degree and a.

CHAPTER 2 indicates the objectives of this work in a clear form. CHAPTER 3 reviews some aspects of comminution regarding mineral liberation and particle breakage mechanisms, ball milling operations, power draw calculation methods and the advances in comminution modeling. A description of the UFRJ mechanistic.

The ball combination mill runs showed the best results in terms of particle size distribution, selection function as well as the breakage function. In terms of the power draw, there seemed to be no link between it and the ball diameter size and it was already established earlier that the power draw depends on the mill loading.
