en.Wedoany.com Reported - The "Pressure Filter Optimization Innovation and Efficient Operation Management" project, independently developed by Jinjie Coal Preparation Plant of China Shenhua Shendong Coal Preparation Center, has been recognized as an Outstanding Case of Employee Technological Innovation Achievements in the Coal Industry of Inner Mongolia Autonomous Region for 2025. The project was officially launched in January 2024, primarily targeting technical challenges related to long-standing operation and maintenance difficulties in the coal slurry dewatering process at the preparation plant.

By optimizing the operating parameters and management processes of the pressure filter, this project effectively enhanced the stability and safety of the coal slurry water treatment system. According to project data, it can save 359,500 yuan in material costs and 829,000 yuan in electricity costs annually, while also ensuring the normal production of lump coal, resulting in significant production increase benefits. As a key dewatering equipment in coal preparation, the operational efficiency of the pressure filter directly impacts the overall production capacity of the preparation plant.

To date, the two pressure filters, 362 and 363, at Jinjie Coal Preparation Plant have achieved continuous, stable, and efficient operation for over two years. The coal slurry water system has consistently maintained high clarity, with no production failures caused by coal slurry water issues affecting the washing process. The equipment failure rate has dropped significantly, earning recognition from frontline staff. The implementation of this project not only solved the plant's own operation and maintenance challenges but also accumulated replicable practical experience for the operation and management of similar equipment.

The project successfully addressed a common industry challenge in the coal slurry dewatering process, forming a standardized operation and maintenance plan, and providing a practical reference for the efficient management of similar equipment in the coal preparation industry. Shendong Coal stated that it will continue to promote the application of this innovative achievement in more coal preparation plants.
