Cement grinding Vertical roller mills versus ball mills

2020-3-23  For the cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of
