Whether in cement works, steel mills or power plants, whether direct or indirect firing: Our ATEX-certified coal grinding plants have proven themselves internationally in all areas of application We also develop custom-tailored concepts for closed-down ball mills in the cement industry
depending on the coal application, have been experienced since the mill grinding capability is directly proportional to available grinding force This implies, for example, that only six (6) or seven (7) mills of the same physical size are required today for a boiler that previously needed eight (8) mills to supply the same coal ,
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 particl
A curve linking moisture content of the coal with mill capacity shows what reduction in capacity will arise if the moisture is excessive This is particularly important with ball mills The particle size distribution and top size may be of importance For ball mills there is a curve linking mill capacity with the top size of coal fed to the mill
