Abstract

The invention relates to mine beneficiation equipment, in particular to mine winnowing equipment. The design adopts a pneumatic structure; the high fall leads the mineral powder to disperse sufficiently; the mineral powder disperses and falls uniformly by a vibration screen; an axial-flow fan blows the mineral powder to a certain distance; as the mineral powder contains various matter elements with different densities, the distances of the blown matters are different, and the linear speed of the movement of the blown matters are also different due to different density. Along the blown distances, due to different densities of the mineral powders, various matter elements with different blown distances and different linear speeds are dropped in different recovery troughs at different distances, thus achieving the separation effect of various matter elements of the mineral powder.

Description

technical field [0001] The patent of the present invention relates to a kind of mine beneficiation equipment, especially a kind of mine winnowing equipment. For the screening of mineral powder, it brings a new type of environmentally friendly mineral powder screening equipment that is simple and feasible, saves electricity and water, improves output rate. Background technique [0002] At present, most of the mineral powder screening equipment used by known mining enterprises are traditional water separation screening equipment, also known as water separation method, water separation method screening equipment such as rolling launder, rotating launder, vertical large helix angle launder, vibration Chutes and more. No matter how the screening structure of the equipment is changed, its basic design mechanism still requires a large amount of water and electric energy to screen out various metal elements in the ore powder through chemical reactions. If the ore powder contains m...
