ball mill use of steel balls as grinding media. 2. Rod mill is suitable for coarse grinding, when product granularity is between 1 to 3mm, processing capacity of rod mill is bigger than ball mill with same specification. 3. Rod mill has certain selective grinding effect because grinding media of rod mill and ores is in line contact.
The following cost advantages should be considered when evaluating rod mill grinding: Rod Mills use low cost grinding media.
