Background

Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be exploited. Can be divided into metal mineral and nonmetal mineral. The ore resource is an important support for economic development and has great influence on the fields of construction, metallurgy, chemical industry and the like. The ore is mined from underground or above ground and then transported to the ground by a mine car or conveyor belt. When exploiting the ore, generally use mining equipment or explosive to separate the ore breakage, not only conveniently transport the ore after the exploitation, can filter according to the size of ore moreover and sell after categorised.

When screening and classifying ores obtained by mining, ore mining enterprises generally pour ore blocks conveyed to the ground or on a conveyor belt into inclined multistage screens, and classify the ores with different sizes through the screens with different specifications. The ore on the screen moves downward by its own weight and the ore having a diameter smaller than the mesh size falls into the next stage of screen. However, in the process of screening and classifying ores, when the speed or the amount of the ores poured into the screen is too large, the ores with smaller diameters move to the bottom of the screen along with the ores with larger diameters and cannot leak out of the holes of the screen, so that the ore screening and splitting effect is poor.

At present, in order to avoid that the ore with the diameter smaller than the aperture of the screen mesh cannot be smoothly leaked, the ore mining enterprises generally adopt the length of the screen mesh to be increased, the ore with the diameter smaller than the aperture of the screen mesh is smoothly leaked through the length of the screen mesh, but the length of the screen mesh is prolonged to increase the time for the ore to move on the screen mesh, and the screening efficiency of the ore is greatly reduced.
