Read OnFine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine …
Read OnThe 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.
Read OnA ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell ...
