Instrumentation And Automation In The U.S. Coal Preparation Industry

This paper presents a review of the state of the art in coal preparation plant instrumentation and a discussion of automation practice that could be applied based on current mineral beneficiation experience and demonstrated foreign technology in coal washing plants. Specific e-mules of applications of remotely controlled slurry values, pneumatic and electronic field transmitters, computers for control and data logging, and on-line analytical instrumentation are given. A program, to demonstrate this technology is described.
