Review on vertical roller mill in cement industry its
2021.1.1 For the past three decades the vertical roller mill has emerged to be the preferred choice for grinding raw materials. With the grinding capacity of a vertical roller mill and the ability to dry, grind and sort in a single unit, the vertical roller mill offers a definite advantage over the ball mill system [10].
