After the implementation of automation transformation in domestic coal washing production lines, production capacity, production efficiency, energy consumption control, and economic benefits have all been significantly improved. The actual gains of many domestic enterprises' landing projects can be supported by publicly available case data. 1, Core performance data of each renovation project
A factory in Huaibei, Anhui: After building a digital twin intelligent control platform, the monthly per capita coal washing volume has increased from 797 tons to 1255 tons; The stability rate between clean coal ash zones has increased by 16 percentage points, the clean coal yield has increased by 0.35 percentage points, and the coal quality qualification rate has remained at 100%; Electricity consumption has decreased by 11%, saving 15 million kWh annually, reducing steam consumption by 44%, reducing standard coal consumption by more than 3000 tons annually, saving production costs by 13 million yuan annually, and achieving a comprehensive efficiency of over 50 million yuan throughout the year.
Ningtiaota Mining Coal Preparation Plant: After establishing an intelligent control system for coal quality throughout the entire process, the raw coal washing rate has reached over 90%, and the coal calorific value has remained stable at 5800 kcal/kg; The accuracy of fault warning has been improved to 98%, the operating time of equipment has increased by 4.59%, the duration of fault impact has decreased by 13.22%, and the coal screening volume has increased by 2.32% year-on-year; Producing 25000 tons of high-quality coal annually, reducing chemical consumption by 15%, and improving the efficiency of filter presses by 30%; Reducing employment by 66 people, saving 9.9 million yuan in labor costs annually, improving production scheduling response efficiency by 40%, increasing clean coal recovery rate by 0.5%, and increasing annual benefits by over 9 million yuan.
Wenjiapo Coal Preparation Plant: After the launch of the digital control platform, 233 production equipment have achieved intelligent scheduling, reducing frontline workers by 33.4% compared to before the renovation. The daily operating time of the equipment has exceeded 22 hours, and the qualified rate of clean coal has remained at 100%.
Changzhi Xiangyuan Open Source Coal Washing Plant: After renovation, the washing automation rate has reached over 95%, manual intervention has been reduced by 60%, and washing accuracy has been improved by 20%; Relying on intelligent coal blending technology, the overall transaction efficiency has been improved by over 30%.
Xinglongzhuang Coal Mine: After promoting the intelligent transformation of the entire washing and shipping process, the unplanned downtime of equipment has been reduced, and the integrity rate and start-up rate have been improved; The intelligent loading system improves the one-time loading qualification rate, shortens the vehicle retention time, and enhances the turnover efficiency of coal transportation.
