Homogenization (BLENDING) In preparing raw meal, raw materials like limestone, clay and iron ore are proportioned and fed to raw mill, where these raw materials are ground and well mixed. However, this mixing is not enough to produce clinker of uniform quality.
Even though not practical mixtures such as C 100 G 0 were evaluated in this work, this was purely from a mathematical point of view in order to obtain a better sampling of the independent variables ( the mixture composition) using a simplexcentroid design.. Resistance to Grinding. A total of 700 ml of each blend were introduced in a m cast iron drum (BICO Bond ball mill), with 285 ...
A review of recent raw mill designs indicates that increasing the maximum design raw material moisture from 4% to 17% would result in a doubling of the installed fan capacity. The separator size ...
Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.
