Anti-clogging Mechanism and Parameter Optimization of Wet Fine-grained Coal Screening
Deep screening is an important way to realize efficient classification of wet fine-grained coal,but the problem of screen surface clogging will occur,the rigid-flexible coupling elastic screening method has been applied to overcome the clogging.This paper explored the influence of feed rate and material moisture content on the screening performance and the related mechanism,and carried out the comparison experiments between the rigid-flexible coupling elastic screening and the rigid screening for 3 mm wet fine-grained coal,to further clarify the spatial distribution law of particles in the screening process.When the external water content is 11.31%,the screening efficiency reaches 83.15%,and the total mismatch rate is 6.40%,which effectively improves the screening performance of wet fine-grained coal.
