The common grinding materials for ultrafine grinding mainly include kaolin, limestone, calcite, talc ...
For primary grinding, the ratio could vary between 1:1and :1. For fine regrinding in open circuit, the ratio ranges from :1 to :1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball sizes.
