spring-loaded, type, vertical spindle mills, each gravimetric belt feeder, seal air fan, 1800 rpm primary air fan, and four mill outlets supplying pulverized coal to one of the three horizontal rows of (4) dual-fuel burners. When operating at boiler MCR, each mill had a coal throughput of approximately 53,000 #ffir.
The coal mill is one of the important auxiliary engines in the coal-fired power station. Its operation status is directly related to the safe and steady operation of the units.
Ball mill has simple structure, low cost, high capacity and convenient maintenance. Vertical coal mill is also called LM series vertical roller mill, and is also widely used in mineral grinding mill industry. Vertical coal mill is big in appearance with high capacity. Raymond Mill is the eary grinding mill, but now is still used widely.

The coal industry directly employed 1,800 people in 2001 adding to the general economy of the State. Presently there are five operating coal mines in New Mexico, four surface and one underground operation. These mines produced 30.53 million tons in 2001, making New Mexico 12th in the nation for coal production. Acknowledgment

Finally, conventional coal mill control is discussed in Lindsley (2000) and Liptak (2006). In the present work, a novel nonlinear coal mill model is derived for model-based real time applications based on a former study (Mercangoez & Poland, 2011). One of the objectives is to consider a trade-off between model complexity and model accuracy ...
Much of this water is held in ultrafine pores in the coal structure. Anthracites and the higher rank bituminous coals have been found to have internal surface areas in the region of about 50 to lOOm2Ig, but more than twice these values may be found with the lower rank coals. ...
