Prediction Model of Suspension Density in the Dense Medium Separation
In the dense medium separation system of coal preparation plant, the fluctuation of raw coal ash and lag of suspension density adjustment often causes the instability of product quality. To solve this problem, this study established a suspension density prediction model for the dense medium separation system based on Long Short Fuzzy support vector machines. In the separation of coal and gangue, the gray scale and texture characteristic parameters of coal and gangue are linearly indivisible together. Therefore, the extraction stability of coal and gangue with nonlinear classifier will be higher. At the same time, many isolated samples and noise points often appear inResearch on intelligent optimization separation technology of coal

Processes Free Full-Text New Approach Study on Dry Coal
Corona electrostatic separation can remove inorganic materials from coal, reduce coal ash content and sulfur content and improve coal quality, reduce air pollution caused by smoke dust, SOX, and COX. The performance of corona electrostatic separation technology in cleaning a middle ash medium-ash, high-sulfur coal was experimentally In addition, the separation tests of three raw coal samples showed that the research results of binary-simulated coal particles composed of quartz sand and clean coal were valid. Under the optimal conditions, the ash content of clean coal products of three raw coal samples can be reduced by 75.65%, 79.03%, and 83.03%, respectively.Fluidization and separation characteristics of gas–solid separation
