Middling coal magnetic separation tailing recovery equipment and process thereof

Abstract

The invention discloses middling coal magnetic separation tailing recovery equipment and a process thereof. The middling coal magnetic separation tailing recovery equipment comprises a middling ganguemagnetic tailing barrel and a fine magnetic tailing barrel, wherein the middling gangue magnetic tailing barrel communicates with a middling coal magnetic separation tailing pipe through a pipeline,one end of the middling coal magnetic separation tailing pipe communicates with a gangue magnetic separation tailing pipe, one side of the fine magnetic tailing barrel communicates with the middle ofa clean coal magnetic separation tailing pipe through a pipeline, a flow guide pipeline is installed on one side of the fine magnetic tailing barrel, and the other end of the flow guide pipeline communicates with the middling coal magnetic separation tailing pipe. According to the middling coal magnetic separation tailing recovery equipment and the process thereof, the clean coal ash content can be effectively increased, the clean coal yield is increased, and accordingly better comprehensive benefits can be brought to enterprises.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a medium coal magnetic separation tailing recovery equipment and a process thereof. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in c...

Problems solved by technology

[0003] For some coal mines, the washed 16-bed coal belongs to low-ash clean coal. The ash content of comprehensive clean coal is usually below 6.5%, and the clean coal content below 8% can meet the sales requirements. The ash content index is far better than customer requirements, and as long as the clean coal If the ash content of coal is below 8%, the price will be the same no matter whether the ash content is high or low, but the lower the ash content, the lower the relative yield of clean coal, and the comprehensive benefits of coal mining enterprises will decrease.
