issues like cost and ease of operation, cost of installation, cost and ease of maintenance, product quality, versatility, etc. The following presents a comparison of the two mill systems with reference to these issues. Grinding process The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball
The lower rocker arm is an important part of the vertical roller mill and its lightweight design is of great significance for reducing the mass and production cost of the roller mill. Firstly, the strength and deformation distribution of the lower rocker arm under working load were analyzed by ANSYS Workbench to determine the maximum stress and maximum deformation.
Vertical roller mill. Vertical roller mill, also called cement vertical mill, it grinds raw materials by the movement between grinding roller, millstone and grinding device. In general the grinding efficiency of vertical roller mill is 80% as much power as cement ball mill, reduce about 30% power consumption. vertical cement mill.
