In April, the iron ore concentrates grade of Pangang Group's Xinbaima Company reached 57.53%, an increase of 0.41% compared to the previous month. This laid a solid foundation for Xinbaima Company to create high-quality products and enhance its market competitiveness.
Since the beginning of this year, Xinbaima Company has been deeply engaged in improving the quality of iron ore concentrates, focusing on production organization, equipment management, and technological empowerment. It formulates monthly production and operation plans, clarifying the production and grade targets for iron ore concentrates, as well as requirements for equipment maintenance, ore mining and stripping. It promptly carries out mine ore blending and moisture control in the filtration of iron ore concentrates, strengthens the maintenance of semi-autogenous grinding (SAG) mills No. 1, No. 2, and No. 3, fully utilizes the spare capacity of tower mills, and organizes production efficiently. It strictly controls the crushing particle size, ensuring that the proportion of -12mm particle size exceeds 96.5%. It conducts weekly inspections of the screens of high-frequency fine screens, promptly replacing damaged ones to avoid equipment "running with defects" affecting subsequent processes. Through measures such as dynamically adjusting process parameters, accurately tracking the steel ball filling rate of ball mills and sharing data in real time, and cleaning the water pipes at the bottom of magnetic separators every shift, it forms a closed-loop management system, creating conditions for improving the grade and recovery rate of iron ore concentrates.
Xinbaima Company coordinates the production and operation of work areas such as iron separation, titanium separation, and concentrate pipelines, synchronously implements planned maintenance of ball mills and SAG mills, and reduces unplanned downtime through preventive maintenance, providing equipment support for quality improvement and efficiency enhancement. It actively promotes the upgrade and transformation of the double-layer screen equipment of SAG mill No. 3, experiments with new material flocculants, and continuously explores new paths for improving the quality and efficiency of iron ore concentrates.
