In a cement plant, the air flow to a raw mill is monitored. The objective of this monitoring is to achieve the highest possible efficiency of the raw mill. Controlling the supply air to such a vertical mill can also lead to considerable energy savings, as the maximum air volume does not always have to be used, but can be adapted to the process.

Additionally, Vác cement plant wanted a system in which raw mill output was collected by the filter without prior separation. This means a very large dust load of about 800 g/Nm 3 reaching the filter. In these conditions, a perfect distribution of gas and dust is …

A – temperature after classifier => hot gas supply. B – mill differential pressure => mill feed rate. C – pressure before mill => position of recirculation gas damper. D – gas volume flow in grinding plant => position of mill fan damper resp. speed of fan with VFD. TP/ Ne- 08 / 04. Main Control Loops –
