Abstract

JSC Sebryakovcement in Mikhaylovka, Volgograd region, is one of the largest city-forming companies and cement producers in Russia. Currently, the company produces up to 3.3 mln t of ordinary and special types and brands of cement per year. JSC Sebryakovcement provided an opportunity to compare the performance of three technologies of clinker production that are used in the global cement industry, namely, the wet, dry, and semi-dry processes. As a result, it became possible to compare the technical and techno-economic parameters that are obtained when these technologies are used for cement production from the same raw materials. Of particular interest is the fact that JSC Sebryakovcement uses raw materials with a high moisture content, which results in some special features at low temperatures that are sometimes as low as –25 °C or even –35 °C.
The process of design and pilot implementation has proven high efficiency of cooperation between the major Russian cement plant and ELSmidth, a universally recognized Danish cement company.

Key words:

wet, dry, semi-dry processes of cement production; comparison of their technical and environmental performance at the same plant; impact of properties of raw materials
