Coal mine crushing device for coal mining

Technical Field

The utility model relates to a colliery breaker technical field specifically is a colliery breaker that coal mining adopted.

Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others. Coal is the most predominant solid fuel, one of the flammable organic rocks. It is formed by that the flourishing plants grown in a certain geologic age are gradually piled up into a thick layer in a proper geologic environment, and are buried in the water bottom or silt, and then are subjected to the natural coalification action in a long geologic age. In the geologic periods of the world, most coal is produced in the stratums of the stone charm, the pilaster, the Jurassic and the third era, which is an important coal-forming era. The carbon content of the coal is generally 46-97%, and the coal is brown to black and has dull to metallic luster. According to the degree of coalification, coal can be classified into peat, lignite, bituminous coal and anthracite.

Present colliery ore crushing device generally includes the rotation axis, the rotation axis surface is provided with broken tooth, the rotation axis is broken the ore when rotatory, again with the ore breakage back, there is the discharge gate to discharge, but present breaker can be different in size the colliery breakage, still need carry out the secondary crushing to great colliery, still need filter the ore granule after discharging like this, seriously influence the normal production and the benefit in colliery, can produce the dust when the colliery drops simultaneously, the healthy problem of giving the scene personnel can cause the influence.
