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.

1 EIA, an independent arm of the Department of Energy, is the primary public source of energy statistics and forecasts for the United States. The estimated amount of new generating capacity is taken from the Excel output spreadsheet for the Annual Energy Outlook 2008 report. Note that EIA forecasts assume no change to the laws and regulations
Mixer Mill MM 500 control. The MM 500 control is a high energy laboratory ball mill that can be used for dry, wet and cryogenic grinding with a frequency of up to 30 Hz. It is the first mixer mill in the market that allows to monitor and control the temperature of a grinding process. The temperature area covers a range from – 100 to 100 °C.

Ball and Tube Mill Ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods. Tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber ...
Pulverisers are one of the major auxiliaries in a coal fired thermal power station. They are used for grinding the pre-crushed raw coal, so that the pulverised product at desired PF fineness can be fed directly to the furnace of the steam generator.
