Grinding is a random process and is subjected to the laws of probability. Grinding steps: i. Primary (Coarse) grinding (generally a rod mill is used)(Feed size as large as 50 mm, product size as fine as 300 microns)(1000 microns = 1 mm) ii. Secondary (Fine) grinding (generally a ball mill is used)(Feed size as large as 0.5 mm,
Jan 16, 2016· In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to maximum separation.
