And Maintenance for Ball Mills I. Installation A. Check the selected mill site to insure clearance for the proposed mill. It is of the utmost importance that the mill should have a good rigid foundation. When calculating the total load on the foundation, or beams in the case of ceiling mounting, fifty percent should be added to the actual.
Shell-supported ball mills are becoming the mills of choice over those with trunnion bearings. Depending on the size of the mill, there are two, four or six sliding shoes per bearing assembly. The expected bearing load determines whether hydrostatically or hydrodynamically lubricated bearing shoes are used. Sturdy and reliable mill bearing.

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.
