Mine introduce central groove scraper / chute: central groove scraper conveyor and the blade is an important part of the loader, provide the main delivery channel for the transport of scraper. Simple, rugged central trough structure, mainly Chinese plate and ledge welded steel structures. Central groove can connected by a connecting pin, installation and maintenance is very convenient! Central trough models: central groove scraper models mainly depend on the applicable model, generally speaking common models 17B, 30B, 40T and the like. Common specifications of the central groove length of 1200mm and 1500mm two kinds, 17B, 30B-type central groove length of each section is 1200mm, 40T type central groove length of each section is 1500mm. Central groove parameters Size: central trough simple structure parameters include length, width, higher dimensions. It depends on the width of the central groove scraper applicable model and the model with a scraper. General common central groove width including 320mm, 420mm, 620mm, 630mm and so on. That is the height of the thickness of the central groove of the central groove, a common 150mm, 180mm, 222mm, 252mm, 300mm and so on. The weight of the central groove: Zaozhuang Mining Equipment Co. Fuxing middle groove / chute due to the different types of weight vary, for example, weight 388 / 30B scraper central trough of about 80kg / section, 620 / 40T middle tank weighs about 150kg / section, 630 / 150C central tank weighs about 244kg / Day.
