Cement grinding unit is a key link in cement plant. To achieve energy saving and consumption reduction in the cement industry, we must proceed from the cement grinding unit. Through a series of research and analysis, the following seven methods can effectively reduce the energy consumption of cement grinding plant. 1.
The increasing use of vertical roller mills (VRMs) in the production of cement to reduce power consumption and CO 2 emissions has resulted in an increasing need for VRM optimisation. As cement producers look to protect profits as well as their environmental reputation, a process audit can identify the root causes of issues to help plan for improvements in power consumption and performance.
The cement calcining system mainly reduces energy consumption by saving coal and power. It is generally believed that in order to reduce energy consumption of the clinker production line, improvements should be made in the preheater outlet temperature, cooler outlet temperature, and clinker temperature out of the cooler.
