The ball and tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size, BBD-4772,

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

A boiler or steam generator is a device used to create steam by applying heat energy to water Although the definitions are somewhat flexible it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure 7–2 000 kPa or 1–290 psi but at pressures above this it is more usual to speak of a steam generator

flow turbines varies based on size of the power plant. The 400-, 600-, and 900-MW plants were simulated with two, four, and six opposed-flow LP turbines, respectively. The steam turbine drives a single 3600-rpm electric generator. Thermal cycles are based on a modified Rankine cycle, which uses feedwater heaters supplied with extraction
