Milling. 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.

Since the first application using an MPS mill to process pulverized coal in Germany in the mid 1960s, there have been over 2,000 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.

The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.
