Holcim Romania dust control improvements

Mar, 19 2012


(Romania) -- Holcim Romania has invested in eight trough chain conveyors for its Alesd cement plant supplied by Aumund Fördertechnik of Germany. The equipment is for dust management and will contribute towards efficient production as well as maintaining clean air. The units were commissioned at the end of February 2012.

Dust management on the heat-exchanger, for example, is optimised by employing trough chain conveyors where they draw off the dust generated and transport it back to the raw meal silos. The same task is also fulfilled on the heat-exchanger and cyclone which were additionally mounted on the cooler. Here the trough chain conveyor feeds the collected dust back into the material stream. The units now installed have centre distances of 14.5 to 27m. Their conveying capacity ranges from 10-40tph.

In 2011, Aumund installed two bucket elevators with central chains at the Alesd plant (centre distance: 28.2m and 27mm respectively) for the cement mill with a capacity of 450tph.

At Holcim’s Campulung works in Romania, which has recently been equipped with a new 2Mta line, Aumund will also install a 450tph bucket chain elevator which will be used for clinker transport. A delivery date has not yet been confirmed but is expected to be this year.
