Apr 09, 2015 Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.
Feb 27, 2020 Product particle size is also one of the factors influencing the choice of ball mill. For example, the upper limit of product particle size of grid ball mill is 0.20.3mm, which is mostly used for the first grinding stage. The product particle size of overflow ball mill is generally less than 0.2mm, which is suitable for fine grinding operations.
