An important link connecting mine production and export sales, efficient operations in the ore preparation process has proven to be the most effective way to improve the value of mining enterprises.
Traditionally, of course, ore preparation process parameters are adjusted manually. But manual adjustment requires skilled operators and multiple iterations, leading to high optimization costs. Plus, the individual learned skills of operators are difficult to share through any kind of knowledge platform, leading to the suboptimal processing of coal.
Huawei's Intelligent Ore Preparation Solution uses the latest innovations in Information and Communications Technology (ICT) — including big data analytics and Machine Learning (ML) — to improve preparation management efficiency, reduce the labor load, and implement a lights-out factory, one where there is such little need for human work that it can operate in the dark. The solution helps customers improve the purified ore outcome, increase ore output, and improve efficiency.
Reduce the fault rate of washing equipment and save on the costs of troubleshooting.
Accumulate real-world Operations and Maintenance (O&M) experience on an integrated O&M platform.
Reduce the requirement placed on operators.
Big data and ML improve efficiency and quality, all while reducing costs.
Heavy medium separation, with qualified density, is pumped into the sorting tank body through horizontal flow and upflow, with the overflow condition maintained. The raw coal enters the tank body from the feed end and the horizontal flow of the heavy medium separation. The gangue in the raw coal has higher density and therefore sinks to the bottom of the tank, moving along with the scraper to the discharge opening, entering the gangue chute. If the density of raw coal is lower than that of the medium, it floats up to the surface and is discharged from the overflow weir along with the horizontal flow. The upwelling current plays a decisive role in stratification.
Based on the raw coal ash content and the target ash content of clean coal, Huawei's Intelligent Ore Preparation Solution generates optimal parameters for the operation of the shallow tank separator to improve coal washing efficiency.
