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.
SOLUTION. The AirFlow P is a sensor specially developed for measuring air volumes in dusty applications. The AirFlow P determines the air velocity with the help of the dust particles in the process. The evaluation unit calculates the measured velocity with an entered line area (v x A = m 3 /h).This makes it possible to obtain an air volume in m 3 /h or a velocity measurement in m/s with the ...
