The control system consists of the following compensators: AGR—controls the opening of the hydraulic valve to create rolling compression force to control strip thickness. ASR—commands voltage to the DC motor that creates the rolling torque and therefore controls the strip speed. LHC—sets the rotational speed reference of the rollers to indirectly achieve the desired material tension ...

The following steps are suggested as ways to help mills prevent this from occurring. Finding The Vibration Source. Excessive vibration is one of the most common problems in hammermills. To locate the vibration source, you should first remove all hammers, hammer roos ano spacers. Then, start the hammermill and run it at operating speed.
Jun 01, 2015· 1. Introduction. In Process industry generally, the processes are complex, having time delays, and may have different type of nonlinearities. Therefore, it is not always possible to control them with a classical control scheme such as a feedback control scheme.
REPRESENTATIVE PROCESS CONTROL PROBLEMS •Process: The conversion of feed materials to products using chemical and physical operations. •In practice, the term process tends to be used for both the processing operation and the processing equipment. •Note: this definition applies to three types of common processes:
