product fineness prediction in ball mills. Ball MillsCylindrical Ball Mill Manufacturer from Meerut. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles so ball mills operate most efficiently by making a coarse product the fine fractions of this then are being separated and the coarse part being returned to the mill inlet. This work presents a hypothesis of a methodology to predict the product size distribution of a vertical stirred mill using a Bond ball mill. The Population Balance Model (PBM) was used to empirically analyze the performance of a vertical mill and a Bond ball mill. The breakage parameters obtained for both grinding mills are compared to

A population balance model originally developed to predict grinding in ball mills by Austin et al. 1984 Rajamani and Herbst 1984 was used to analyze the test results. The results show the applicability of using population balance modeling in estimating the product particle size distribution from a laboratory vertical stirred mill.

### validation process of ball milllakeviewlodge

Ball mill classifier systems have been improved over time and are now capable of achieving much finer products. In the past a particle size with a D97 of 10 microns was only possible. Now particle sizes down to a D97 of less than 3.5 microns can be achieved with a D50 in the range of 1.5 microns. As a result increased energy inputs are necessary to raise the number of collisional events in a mill contributing to the comminution of fine particles. In this study a research program was designed and implemented to predict the performance of a laboratory scale vertical stirred mill using a Bond ball mill.

grinding media size distribution in ball mill. A simple model based on a population balance analysis similar to the one used for the prediction of ball size distribution in ball mills was used to compare predicted and actual load size distribution in continuous autogenous and semiautogenous pilot plant tests in the 1.75 m diameter mill. In this paper the difference between ball mill grinding and stirred ball milling is discussed. A size-energy model is proposed for simulation of stirred ball milling. The product size distributions below 10 μm from a stirred ball mill were simulated by the model satisfactorily. The model is
