Abstract: To improve the practical application effect of the on-line monitoring system of pulverized coal fineness, the on-line
monitoring system of pulverized coal fineness was tested. This paper introduced the coal mill separator, and studied the
application of the on-line monitoring system of pulverized coal fineness from the aspects of the working process of the pulverized
coal fineness online adjusting equipment and the sensitivity of the pulverized coal fineness online measuring equipment. The test
results show that the system can flexibly respond to the adjustment of the revolution speed of the coal mill separator, which further
proves that the on-line monitoring system of pulverized coal fineness can better monitor the coal fineness.

Key words: pulverized coal particles; coal mill separator; image method; on-line monitoring system of pulverized coal fineness
