With analysis of the phenomenon that coal fines adsorb to the belt surface on coal conveyor
a new idea focused on improvement in the surface topography of conveyor belt to decrease adhesion of coal fines is presented on the basis of inspiration from the biological self-cleaning phenomenon and perspective of bionics.The surface topography with papillary structure of conveyor belt surface is designed on the basis of Lotus-leaf-likes surface with analysis of its microstructure in accordance with similarity principle.The new structure could effectively prevent coal fines from adhering to conveyor belt surface.A model of the new structure is also built.
