Analysis of the Application Effect of Pre-desliming and Selection Process
In order to solve the problem of difficulty in ensuring the yield and quality of clean coal in actual sorting operations for high ash and high mud coal slime,based on a detailed analysis of the current flotation process status and existing problems in coal preparation plants,the type of rough flotation machine in the pre-desliming and selection process is determined,and the sorting effect of individual selection is analyzed.The flotation process consisting of pre-desliming,rough selection,selection,and dehydration was validated through industrial experiments to achieve the expected flotation effect and product quality for high ash and high mud coal slime.
