Vertical roller mill and ball mill performance competition
The vertical roller mill is soft at work, usually around 80 decibels. The grinding roller is not in direct contact with the grinding disc, and the noise is about 20-25 decibels lower than that of the ball mill. The vertical roller mill adopts integral sealing, and the system operates under negative pressure, with less dust and clean environment.
