Cascade Control Loop Rotary Kiln

AC drive with PID control loop

AC drive with PID control loop This raw material is heated up to 1400 o C by the rotary kiln, transformed to clinker, which is a material with a granulometry of about 2 inches and below. And, after this is produced at the outlet of the kiln, it has to be cooled by ambient This is called cascade. If the flow should change on a relative.
