Gravity screening winze device and construction method thereof

Abstract

The invention discloses a gravity screening winze device and a construction method of the gravity screening winze device. The gravity screening winze device comprises three winzes arranged in parallel, wherein the left and right winzes positioned at two sides are parallel to each other, the included angle between the left and right winzes and the level is 57 to 63 degrees; the included angle between the middle winze positioned at the middle position and the level is 37 to 43 degrees, and the middle winze extends to the right winze and is communicated with the right winze; the side wall of the middle winze close to the left winze is provided with a grid-shaped slide screen; a connecting winze is interconnected between the middle winze and the left winze; the connecting winze is communicated with the middle winze at the side wall facing the slide screen, of the middle winze; an ore drawing gap is arranged between the side wall, facing the slide screen, of the middle winze and the slide screen; the included angle between the middle winze and the level is 47 degrees to 53 degrees; and gridding screens formed by round steels are respectively arranged on the inlet of the middle winze and the right winze.

Description

technical field [0001] The invention relates to ore screening equipment in mining production, in particular to a gravity screening slide device, and simultaneously the invention also relates to a construction method of the gravity screen slide device. Background technique [0002] At present, the vast majority of domestic phosphate rock enterprises mine the rich and abandon the poor, and abandon the ore that does not meet the economic taste, which will inevitably lead to serious ore dilution. In order to effectively utilize the country's rare resources, it is necessary to mine the thin ore body in full layers, and in order to improve the grade of the ore, it is inevitable to sort the mined ore. The sorting work in the prior art is generally on the ground. It is carried out on the ground, which requires that the mined ore, whether it is rich ore, poor ore or simple stone, must be transported to the ground together, and then sorted, which will cause a lot of waste of manpower ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a gravity screening chute device with simple structure and good dust removal effect, so as to solve the problem of transporting rich ore, lean ore and stones to the ground for sorting when mining thin ore bodies in full layers in the prior art. The problem of high mining cost caused by selection, meanwhile, the purpose of the present invention is also to provide the construction method of the gravity screening chute device
