New bag filters

The Ukrainian cement producer Doncement, a subsidiary of the HeidelbergCement Group, has awarded Intensiv-Filter, the leading specialist in filtering installations, a contract for a bag filter, including fans and dust transport system for dedusting of the rotary kiln. The bag filter replaces the two existing electrostatic precipitators. Intensiv-Filter is responsible for the design, manufacturing and supervision of assembling and commissioning of the installation that should start running in the spring of 2010. The bag filter is designed and equipped with a fully automatic cleaning control system for a gas volume of approximately 600 000 m³/h a. c. and filter bags of 8 m length. In addition to the process filter, Intensiv-Filter delivers two bag filters for the cement finish mill, each with 22 000 m³/h a. c.

In 2008, Intensiv-Filter received the complete contract for the supply, installation and commissioning of a bag filter of the type “ProJet mega^®” for one of the largest cement plants in Northern Europe. The client was the Cementa AB, a subsidiary of HeidelbergCement. The plant is located in the city of Slite on the Swedish island of Gotland. After only six months of construction, the new and within the HeidelbergCement Group the largest bag filter for the dust removal from the rotary kiln line 8, was successfully put into operation in early November (Fig.).
