Description

Coal mine production processing screening plant convenient to adjust mesh aperture

Technical Field

The utility model relates to a coal mine production screening technical field specifically is a coal mine production processing screening plant convenient to adjust mesh aperture.

Background

The method is an area for mining coal resources in a coal-rich mining area by human beings, and is generally divided into a mineworker coal mine and an opencast coal mine. 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.

In coal mine production, some articles are often required to be used according to different particle sizes, the classification of the sieves is very fine, the workload is large, the demand of the sieve plate of the sieve screen is also large, but the principle of sieving the sieve plate of the same sieve screen is as follows: the materials larger than the aperture of the sieve plate are on the upper layer of the sieve plate, and the materials smaller than the sieve holes fall from the sieve holes to be sieved, so that the sieving machine with each aperture can only sieve the materials with certain particles, if the particle size is changed, another sieve plate needs to be replaced, which wastes labor and materials and is really troublesome. And the screen cloth of whole grain machine contains fixed sieve mesh usually, can only sieve the medicine that corresponds the particle diameter, if need sieve out the material of different specifications, then need change the screen cloth that has corresponding aperture, complex operation.
