Coal Mill Level Monitoring Sytem for a Roller Mill

03/03/2014 9:31 AM

Does anyone know which technology i can use on a 'Raymond Bowl' roller mill to measure the level of coal in it remotely in a thermal power plant. I know the Milltronics acoustic system can only be used on 'Ball Mills', which similar technology can i use on the roller mill?

Please list the suppliers contacted so far so that these may be eliminated from further suggestions. Start the list with the mill's original manufacturer, please.

Consider mounting the whole shebang on load cells, and go by weight.

I worked on a Milltronics ball mill control system years ago and for what I recall sound pressure was only one process variable used to measure mill load. The other variable was motor power. Perhaps a measurement of motor power in your roller mill would yield acceptable results?

Thanx, the power option sounds the easiest and most convenient to implement
