Abstract

PT Semen Padang, as the largest Cement producer in Indonesia, employs a multi-stage Cement production process, comprising a Raw Mill, a Kiln, and a Cement Mill. The Cement Mill process, serving as the final grinding stage, plays a crucial role in Cement production. Here, clinker, gypsum, pozzolan, and limestone are mixed and ground into Cement, facilitated by grinding media and impact or tumbling forces. This study aimed to investigate the hot gas requirements and efficiency of the a Cement Mill unit, with a focus on the mass balance and energy balance of the Indarung V Cement Mill at PT Semen Padang. The results indicated that the mass of air utilized in the a Cement Mill unit was 132.96 tons/hour, while the water requirement was 3.68 tons/hour. The total mass balance value was 336.95 tons/hour, and the total energy balance value was 4,213,679 Kcal/hour.

Abstract

This research aims to analyze the impact of False Air on the increase in Oxygen (O2) percentage in the Coal Mill at PT Semen Padang Indarung V. False air or unwanted air leakage is a serious problem that can affect the efficiency of Coal Grinding processes and combustion quality in the Kiln. The research was conducted using operational data collection methods over 6 months, including measurements of O2 levels, Mill Temperature, differential pressure, and Grinding Efficiency. The analysis results show a significant correlation between increased False Air and Increased O2 percentage, where every 1% increase in False Air causes a 0.5% increase in O2 levels and a 2% decrease in Grinding Efficiency. Other identified impacts include an Average Mill temperature decrease of 5°C, a 15% increase in ID Fan power consumption, and a reduction in Grinding capacity of up to 10%. The implementation of improvement programs such as seal replacement, Mill housing repair, and ventilation system optimization has been proven to reduce O2 levels to reach the ideal value of 3-4% and increase grinding efficiency. This research contributes to understanding the influence of False Air on Coal Mill performance and can serve as a reference in preventive maintenance programs to prevent air leakage in Coal Mill systems.
