Many cement plants use coal and pet coke as the main fuel for the kiln to reduce their energy cost. Normally coke and coal contain sulfur and moisture in varying quantities. These fuels usually to go through a mill to obtain the right particle size and then need to get dried, usually with the hot gases from the kiln.

Madrid was founded in 1869 near the site of sporadic gold prospects. It wasn't until the 1890's, when the rich coal beds in the area began to be mined on a large scale, that Madrid became a company coal town and a regional mining center with several thousand inhabitants. Today Madrid is a popular artists colony and tourist destination.
The U.S. Geological Survey (USGS) reports that Mexico produced 11.9 Mt of coal in 2007, which was an increase of 9% compared with production in 2006. In 2008, Mexico produced 9589 kt of sub-bituminous coal. The same year Mexico imported 2696 kt of sub-bituminous coal. Coal Consumption. Mexico consumed nearly 21 million short tons of coal in 2019.
Coal fired power plants are heavily used due to large and long lasting coal resources compared with oil or natural gas. An important bottleneck in the operation of this particular kind of plants, however, is the coal pulverization process, which gives rise to slow take-up rates and frequent plant shut-downs (Rees & Fan, 2003).In typical coal fired …

The coal mill is a key ancillary to any pulverized fuel boiler. It grinds the coal to a fine powder so that it can be burned with maximum efficiency. Biomass also moves through hammer mills, dryers and pulverizers during the production process. Avoiding mill explosions is essential for personnel safety and asset protection.
