Automatic Control Of Ultrafine Vertical Mill

[gjsohcat]

Vertical roller mill system is a complex system with multiple input, multi output, nonlinearity, time-varying, large lag and multi variable coupling. The influence of many factors makes the mathematical model difficult to establish accurately with the change of environmental conditions.

The effective and perfect automatic control of LM series vertical roller mill can make the system adjust to the best working point, reduce the consumption of powder and reduce energy consumption. Because the automatic control of LM series vertical roller mill is more and more important in the field of mines at home and abroad.

For a specific LM series vertical roller mill, it is assumed that the structural parameters (such as mill specification, liner shape and material) and motion parameters (such as mill speed rate) are unchanged, and the operation parameters of LM series vertical roller mill and ground material will also change with time, which will affect the grinding output and energy consumption. Therefore, it is very important to detect the load of LM series vertical roller mill (including medium filling rate, ball ratio and grinding concentration) in automatic control.
