For observers in some quarters, it might sometimes seem as if the rapid rise of remote and hybrid working patterns over recent years has merely been an incidental consequence of the COVID-19 pandemic.
Certain data might seem to back up this view. As of 2019, for example – just prior to the pandemic – only 4.7% of UK employees worked from home.
Fast-forward to April 2020 – when the first lockdown was in place – and some 46.6% of UK employees did at least part of their job from…

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.
