Abstract

Abstract. The water spray system in a finish mill plays a vital role in maintaining material temperature and grinding process stability. Manual control often causes fluctuations in the outlet temperature, leading to suboptimal operations and excessive water consumption. This study aims to implement a Proportional-Integral (PI) control on the water spray system to improve thermal stability and water use efficiency. The methodology includes designing the control system, determining parameters through a tuning process, and testing system performance by comparing conditions before and after implementation. The results show that PI control significantly reduces temperature deviation and accelerates system response time compared to conventional control. By maintaining the product output temperature at a stable setpoint, the application of PI control is proven to reduce water consumption by up to 20%. These findings indicate that the system can operate more optimally without compromising product quality. The implications of this research confirm that PI control is effective in increasing resource efficiency and has high potential for standardization across other grinding units in the cement industry.
