Grinding uses up around one third of the electrical energy requirements of each integrated cement plant, so that improvements in grinding processes can have a huge impact in overall electrical energy demand. The conference will look at new technologies in grinding, as well as grinding efficiency improvements.
The heat produced by the clinker is circulated back to the kiln to save energy. The last stage of making cement is the final grinding process. In the cement plant, there are rotating drums fitted with steel balls. Clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it ...
The basic function of a dust collector in the cement industry Cement production plants heavily rely on dust collectors that are represented in significant numbers. In most cases, the core of the cement plant is the Kiln and a dust collector connected to the Kiln. It is common practice that Kilns are running 24/7 all year round together with its primary filter collector.
