Difference Between Raw Mill And Ball Mill Detail Detailed Information Description

The difference between ball mill and vertical mill in cement grinding over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials the grinding efficiency of the vertical roller mill combined with an ability to dry grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system
