May 01 1984 · 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

Grinding machines use friction attrition or compression to smooth out a metal product s surface.There are several types of grinding machines designed to deliver different levels of finite smoothness. For example a ball-grinding mill is an excellent fine grinder for cement products but may not work for more extensive smoothing projects.
