Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into miners and opencast mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine.

The raw ore mined from the coal mine is separated by a centrifuge, and the separated material is discharged from a discharging chute. The centrifuge is easy to block a blanking chute due to the fact that the discharged material is high in moisture; the manual cleaning risk is large, and the product quality is easy to reduce after the washing by water.
