The design of such grinding mills is extremely critical, requiring sophisticated software tools, proprietary calculation worksheets, and experienced technical engineers and drafters. This blog will review how the mill design process has changed over the last 30 years. While most of the changes have been positive, new issues and problems have risen in the process.

parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling was deemed unsuitable for this purpose.

involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
