Description

A coal mine crushing device

Technical field

The utility model relates to the field of coal mine processing technology, in particular to a coal mine crushing device.

Background technique

Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seams are far from the surface, they generally choose to excavate tunnels underground to extract coal. This is an underground coal mine. When the coal seams are far away from the surface, When the ground surface is very close, it is generally chosen to directly peel off the surface soil layer to excavate coal. This is an open-pit coal mine. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal. It usually includes roadways, shafts and mining surfaces. Etc. Coal mined in coal mines is the main solid fuel and a type of flammable organic rock. In order to facilitate use and transportation, crushing devices are generally needed to break larger coal blocks.

When the traditional coal crushing device is used, the coal is generally transported to the interior of the device through a conveying device, and then crushed by two sets of crushing rollers. Although the crushing efficiency and effect are relatively good, in actual use, Crushing coal will produce a large amount of coal dust. The dust will float into the external environment through the feed port of the device. On the one hand, it will cause environmental pollution. In the later period, a lot of financial resources and manpower will be spent to renovate the environment. On the other hand, it will also cause damage to the ongoing operations. The installation caused physical harm to workers and required improvements.
