The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%.

Types Of Coal Pulveriser. Slow speed mills like ball mill; Medium speed mills like bowl mill; High speed impact mill; The slow speed and medium speed mills are selected for coals ranging from sub-bituminous to anthracite. The high-speed mills are used mainly for lignite. Operation Of Bowl … See more

1. The hot air dries the coal. 2. The hot air is used for transportation of the recirculating coal within the mill and also for. transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided ...

A crusher is a machine designed to reduce large Coal into smaller Coals, gravel, or rock dust. crushers are machines which use a metal surface to break or compress materials. Mining operations use crushers, commonly. Figure 1: Coal Handling Plant. 451. Int. J. Mech. Eng. & Rob. Res. 2013 Girja Lodhi, 2013.
