Product Introduction
Coal scraper conveyor apply to slow gently inclined thin coal seam working face conveyor of coal. Mining height are broken floor to 0.6 m, dip Angle of coal seam is not more than 25 degrees is more suitable for hard coal, large blocks or more inner dirt band conveyor coal.
Main Characteristics
The scraper conveyer 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,it can be significantly improved to prevent environmental pollution.
