Russia: Katavsky Cement has modernised rotary kiln No. 4, raising clinker production capacity by 15% from 888,000t/yr to 927,000t/yr. According to Cemros, the project formed part of a corporate programme of improvements to increase production efficiency, valued at around US$760,000. Specialists reportedly encountered the problem of clinker defects when increasing the feed of raw meal due to insufficient heat exchange in the kiln system. To eliminate the problem, the plant updated the cyclone heat exchanger, stabilised the air supply and combustion of additional fuel, and improved the clinker cooling system.
General director Vyacheslav Lyubimtsev said “Modernisation of kiln No. 4 is a consistent step in the development of the plant. In 2024, similar work was carried out to increase the productivity of furnace No. 3 by 30%. The new result confirms the effectiveness of the chosen strategy.”
