SHORT DESCRIPTION Cast iron ball set in a wooden plaque. NOTES This item was used in the coal pulverizer.Efficient coal combustion requires that all the carbon particles in coal should get sufficient air to burn and release the heat. When coal is burned on grates without any change in size or pulverizing its large size means that some of the carbon particles do not come in contact with the.
Oct 23, 2021 The pulverized coal is obtained by grinding the raw coal in pulverisers called pulverising mills. The various types of mills used are ball mill, hammer mill, ball and race mill, bowl mill etc. Every type of mill has the means of reducing the size of coal e.g. in case of ball mill the coal is crushed in a drum having steel balls.
