Cement production requires significant energy, leading to high costs and CO2 emissions. This is because clinker production and grinding must be performed with a very high level of fineness. Grinding aids used in the grinding process can improve production and fineness and decrease energy consumption by reducing the agglomeration of particles and protecting the balls and liners in the mill. This study aims to compare the effects of three different grinding aids on clinker grinding using a ball mill. A commercial grinding additive, triethanolamine (TEA), and two industrial grinding aids (GAA079 and GAA088) obtained from the cement industry for grinding using a ball mill with dosages of 0.05, 0.25, 0.50 and 1.00 wt%, respectively. The industrial grinding aids were characterized using gas chromatography-mass spectrometry (GC-MS). Particle size and morphological analyses using SEM and XRD were performed on the samples. The grinding aids produced smooth edge particles, which reduce the specific surface area, affecting the quality of the cement. XRD showed no significant structural distortion with or without grinding aids, and it was also found that the grinding aids helped decrease ball coating during the grinding process. This study is significant because it explores the potential benefits of using different grinding aids in cement production. The use of grinding aids in the grinding process can significantly improve production and fineness while decreasing energy consumption, which can help reduce the costs and CO2 emissions associated with cement production.
