The Functional Performance Equation for ball milling circuits provides plant staff with a new means to improve circuit performance. However, successful execution of a plant project, with verifiable circuit processing performance improvements, requires a significant number of accompanying steps beyond the equation alone. In order to identify and articulate all these steps, a study with plant staff from two milling operations and a grinding media supplier was undertaken. ?Task analysis? of improving plant grinding performance was carried out. This analysis called for the development of a number of system components, and ultimately yielded a ?Plant Grinding Circuit Processing Performance Management/Improvement System.?

The Functional Performance Equation for ball milling circuits provides plant staff with a new means to improve circuit performance. However, successful execution of a plant processing performance improvement project, with verifiable improvements, requires a significant number of accompanying steps beyond using this equation. In order to identify and articulate all these steps, a study was undertaken with the metallurgical staff from two milling operations and process application specialists from a grinding media manufacturing company. “Task analysis” of improving plant grinding performance was carried out. This analysis identified the required steps, and ultimately yielded a “Plant Grinding Circuit Processing Performance Management/ Improvement System.

ENGINEERING educators have recently been discussing the advisability of extending the undergraduate curricula to five or six years, and a plan has also been proposed requiring a preliminary period of study in the liberal arts college before admission to the engineering college. Extension of the undergraduate curricula has been suggested as a means of more fully covering the subject matter in the major field of study. Interest in this proposed plan of requiring a preliminary period of study in the liberal arts college has been heightened through a bill recently introduced in the legislature of the State of New York. This plan intends to give a more professional status to engineering, and credit for these additional years of study would be allowed to those engineers applying for professional licensure. As a result of the interest in engineering curricula and due to the impetus given by these proposed plans a general reexamination of curricula has been conducted by a large number of schools with the stated purpose of determining if the present curricula are meeting the aims and scopes of engineering education.
