Conversion of clinker burning kiln to coal at Rohoznik cement plant in Slovakia

In mid- 1995-s, Hirocem's Rohoznik cement plant in Slovakia converted both its dry lines with rotary kilns to coal. The conversion of the kiln lines, that had earlier been operated on natural gas and fuel oil, to coal was caused by economic reasons.
In addition to putting up two grinding-anddrying installations equipped with two MPS 180 K plate roller mills from Gebr.Pfeiffer, and the commissioning of silos, proportioning and burner equipment and safety systems, a round blending bed was also installed. The selected installation concept has done well in terms of both production and technology. The safety concept, which, as is well known, in case of conversion to coal must meet high requirements, has also done well. A description of this concept is provided. Also described is the production experience gained over the many years in operation.
