AI Technical Summary
Traditional vibrating fluidized bed separators rely on human experience for control, lacking precise reference standards. This results in time-consuming and inaccurate control, failing to provide timely and accurate guidance for production parameter adjustments.
By calculating the measured bed density, rated throughput, and measured difference in ash content between raw and clean coal in the fine coal separation system, and combining parameters such as magnetite powder medium content, coal powder medium content, total binary weighting mass, airflow velocity, and bed density uniformity and stability, automated control is achieved to ensure data accuracy and rapid response.
It enables rapid and accurate control of the coal fines separation process, and can flexibly adjust production parameters according to changes in raw coal quality and product demand, thereby improving production efficiency and resource utilization efficiency.
