PARAMETER OPTIMIZATION OF LARGE SAG MILL LINER BASED

Abstract The authors analyze the influence of the semi-autogenous (SAG) mill parameters on the mill grinding efficiency, energy consumption and the tangential cumulative contact energy. This paper provides a new liner parameter design and optimization method, which offers theoretical guidance for the optimization design of liner In the past century, many research studies have investigated the stressing conditions in stirred media mills. Researchers developed a broader and better understanding of breakage mechanisms and breakage energy used in stirred media mills [3,4,5,6].Since the process optimization is a time-consuming process due to several Dynamic Process Models for Fine Grinding and Dispersing

Experimental Analysis of Semi-autogenous Grinding Mill

In recent years, many studies have been devoted to the development of mill diagnostic tools to find parameters that affect grinding efficiency. Zeng and Forssberg ( 1993,1994 ) have correlated signal characteristics to grind parameters such as power draw, feed rate, pulp density and product size by generating power spectra of the of circulation grinding with small media (see Figure 2, p. 14).* The mill is designed to accommodate media from 0.3 to 1.0 mm, and a screening mechanism was developed that allows for high prod-uct flow without media plugging. This is accomplished by having a screen of rings separated by appropriately sized spacers between them.Media Milling Advances Union Process
