coal feeder calibration

  • Sampling and Testing in Coal Quality Management

    CALIBRATION TESTING. The coal flow, moisture variations and other conditions that can have an effect . on the coal stream or coal characteristics must be reviewed. The number of seams, coal types or blends to be used in the test must be established, and the widest range of ash and sulphur


    Run feeder in local (SSL in RUN) and verify that when coal on belt paddle is actuated, feeder trips after about 2 seconds. Run the feeder and check CMMR contact is operated now. Put feeder off. Thread in the calibration probes at the designated locations after removing the caps. These should engage on the punch mark on the feeder.

    feeder, therefore, discharged exactly 100 pounds of coal for each turn of the head pulley. Ihe head pulley speed was proportional to the rate of coal fed that could be expressed as pounds of coal per minute or pounds of coal per hour, as desired. Total turns of the feeder head pulley times 100 equaled the pounds of coat fed during any given period.
