In a coal-fired power plant, one of the main equipment is the coal mill, whose effectiveness influences mainly the whole power plant performance (Shah, Vuthaluru, and Vuthaluru 2009 ).

A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.

Bowl mills are one type of grinding mill used in a coal-fired thermal power plant. Raw coal fed into the mills gets converted into pulverised coal and carried to the burners by primary air.

Great River's original plan was not only to close Coal Creek, but to build a $1.5 billion wind-power project that would have connected into the power line at the coal plant.

Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

Tube mills: The tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. If the length of the cylinder is greater than the diameter of the cylinder, it is called a tube mill. fTUBE MILL These are slow speed Mills. The Mills are designated as BBD-4772 Where, B Broyer (Name of inventor).
