In terms of the internal structure of vertical roller mill, we can start from the following two aspects: medium and lining plate. According to the current use of vertical roller mill in China, the grinding media are mostly spherical, cylindrical and gravel.
Years of research has shown that in the normal particle size range, the use of spherical medium is effective and cheap, and the grinding particle size of spherical medium is finer.
In addition, the contact mode between media and materials and between media also has a great influence. Although spherical medium is widely used in China, because its crushing mode is mostly point contact and the crushing force is large, it is also easy to lead to over crushing.
