To dedust the exhaust gas streams from kilns, clinker coolers, bypass systems, raw mills, cement mills and dryers, Polysius installs both electrostatic precipitators and bag filters. They can be combined with an exhaust gas cooling system using water injection or gas-air heat exchanger.

The dedusting systems are designed to suit the particular requirements of the process and the emission limit values.

Among the plant components equipped with high-performance bag filters are silo installations, crushers, loading facilities and pneumatic and mechanical conveyors.
