Difference Between Vertical Roller Mill and Ball Mill. Vertical roller mill and ball mill both of them can be used in many different kinds of stone powder making. However as two common use stone powder there are many difference between these two mills in this article we will mainly talk about the difference between vertical.

The difference between the two is that the discharge method of the vertical mill is more forced, and the discharge method of the ball mill is more free. When the material is processed inside the vertical mill, it is rotated by the high-speed rotation after being rolled by the grinding roller.

The cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1. In addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2. Discharging way of ball mill and rod mill

Vertical Roller Mill VS Ball Mill. First of all, from the appearance point of view, there is a big difference between the vertical mill and the ball mill. The vertical mill is presented vertically and three-dimensionally from the ground, while the ball mill is lying horizontally on the ground and covers a relatively large area.

3. Different grinding media The grinding medium of the ball mill is steel balls with a diameter of less than 100mm; while the rod mill usually uses a steel rod with a length of more than 500mm as the grinding medium. 4. Different filling rates of grinding media
