Some correlation exists between free silica quartz content in coal and wear in mills. 19. 15.5. Coal’s contribution to cement clinker 15.5.1. Coal ash. When coal is used as a fuel in a rotary cement kiln a large amount of the ash formed from combustion is absorbed into the clinker as it is being produced in the kiln.

Prior to the coal grinding plant a coal pre- drying plant will be installed. In a first step the pre-crushed coal < 25 mm will be pre-dried using higher temperatures than allowed for pulverized coal at a reasonable airflow and a low pressure drop. In a second step the coal will be ground to the requested fineness and further dried if ...
Since the first appli ion using an MPS mill to process pulverized coal in Germany in the mid 1960s there have been over 2000 different MPS mill installations operating in coal-fired power plants worldwide. As one of the most popular coal pulverizers in the utility industry the MPS mill was first introduced into the US in the early 1970s.
