This article presents an analysis of various techniques that contribute to enhancing the efficiency of cement clinker grinding, and their implications for the quality and technical properties of cement.
The study considers not only conventional, but also novel substances used as grinding additives, including coal, carbon black, triethanolamine, rosins, lignins, as well as novel components such as "Lithoplast IP1", InCEM, and MC-GRINDINGPRO 01.
Special attention is given to the most promising grinding intensifiers, particularly "Lithoplast IP1", which has significantly increased mill productivity by 11.1–19.2% while reducing power consumption by 8.9–15.6%. The ar-ticle presents the results of tests that demonstrate the positive impact of this additive on the flowability, grinding and physico-mechanical properties of cement. The benefits of using the "InCEM" intensifier, including the potential to enhance the strength characteristics and optimize the grinding process of cement, are also discussed.
A separate section of the article focuses on the work of researchers M.A. Goncharova, L.V. Zamyshlyaeva, and H.G.H. Al-Surrawi on the use of energy-efficient domestic intensifiers like IP-1 and IM-2. These authors analyze the impact of these additives on the initial strength of cement and grinding efficiency.
According to the results of the study, the introduction of compounds IP-1 and IM-2 into cement has been shown to increase its initial strength by 3.7 MPa and decrease the coefficient of water absorption, thereby improving the quality characteristics of the final product.
Based on these findings, the article emphasizes the significance of grinding intensifiers in enhancing the effi-ciency and quality of cement production, as well as in reducing operational costs and enhancing the reliability of building materials.
