Ball mills 5.5 m 18 ft in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills particularly when the large mills carry 40 by volume ball charges. This paper will explore factors used in scaling up ball mills showing where the advantages of one factor can possibly be negated by another factor. The paper will propose possible operating

Ball Mill Circuit Functional Performance Equation. The above described parameters for system breakage and classification system efficiency factor the overall task of the ball mill circuit into its two distinct basic functions namely fines generation and fines removal. The effect of design and operating variables on each can be studied

Optimiation of mill performance by using online ball and pulp measurements Soon after a stop a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but often they are stopped around about the same time.
