Introduction of SGD-280/11 Underground Incline Scraper Chain Conveyor
SGD-280/11 Underground Incline Scraper Chain Conveyor applies to slow gently inclined thin coal seam working face conveyor of coal. Mining height is broken floor to 0.6 m, dip Angle of coal seam is not more than 25 degrees. SGD-280/11 Underground Incline Scraper Chain Conveyor is more suitable for hard coal, large blocks or more inner dirt band conveyor coal.
Main Characteristics of SGD-280/11 Underground Incline Scraper Chain Conveyor
SGD-280/11 Underground Incline Scraper Chain Conveyor has simple structure. It not only can convey in the level and vertical transmission, but also can be combined in layout, cascades transmission, does more feeding and multi-point discharge. It is more flexible in art processing. Because the shell is closed in the transportation of materials, so it can be significantly improved to prevent environmental pollution.
