  • Coal Mill Monitoring

    Coal mills are used at power stations to pulverize coal to a fine powder so that it can be fed into boilers in a controlled manner. However, it is very difficult to monitor and control the conditions inside the mill, which can make their operation inefficient and can also lead to the mill becoming inoperable. Sometimes, it can cost a power station over a million pounds a year to maintain their mills in an operational condition.
