Pulverizer
Pulverizer. A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of coal power plants .For instance, in the steel industry coal is used as a raw material to produce coal coke. 2.

Coal utilization in the cement and concrete industries
Some correlation exists between free silica (quartz) content in coal and wear in mills (Juniper, 1999). 18.5. Coal’s contribution to cement clinker18.5.1. 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.Coal’s grip on the global electricity sector is loosening as more utilities and companies invest in renewable energy. But one major coal consumer—the steel industry—is finding it harder to kick its habit. Steel companies make nearly 2 billion tons of high-strength material every year for bridges, buildings, railways, and roads.How steelmaking may go carbon-free—by dropping its addiction to coal

What type of crushing machinery to choose for coal grinding?
Hammer Mills: Hammer mills are a popular choice for coal grinding because they can handle both dry and wet materials. They work by crushing the material with a series of rotating hammers, whichFor high production of crushed coal it is better to use the hammer mills having higher contact surface of hammer. Hence, it is easy to produce the high rate of crushing coal with in less time.The purpose of the crushing Design and Fabrication Of Hammer Mill Mechanical

Coal to Make Coke and Steel University of Kentucky
Metallurgical coal (also called "met" coal) is an important raw material used in the steel-making process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile
