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.
