The coal is a very important raw material in the steel industry [6]. It is extracted in the form of solids of con-siderable size and as such form may not generally be burned, sintered or gasifi ed. So it must be properly com-minuted. Grinding of coal generally uses two types of crush-ers, namely, the drum crushers and the hammer crush-ers.

Introduction. This article concerns itself with vertical grinding mills used for coal pulverization only (coal pulverizers), although vertical grinding mills can -and are- used for other purposes.. The 3D model in the saVRee database represents a vertical grinding bowl mill.Other grinding mill types include the ball tube mill, hammer mill, ball and race mill, and, roll and ring mill.
Coal ball mill is a machine that crushes and grinds the coal briquette into pulverized coal. It is important auxiliary equipment of pulverized coal furnace. During the coal grinding process, the coal is crushed and its superficial area increases continually. To add new superficial area, the bond between solid molecules must be overcome, so the ...

In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
Coal ball mill is the main equipment for grinding pulverized coal. The raw material of coal powder is coal with various hardness, and it drying in the coal mill grinding process to obtain finished coal powder which can be efficiently burned.
FOR TUNNEL KILN: it is required a burner that can guarantee a controlled fuel / air ratio for each feed nozzle, a good size with a constant particle size of less than 1 micron of the fuel; it does not need to be manageable. it is the most sophisticated solid fuel burner in the world, The production of the coal powder according to a well determined and constant granulomentry is performed ...
