Abstract: The Face scraper conveyor of the machine and its head, tail, the central trough, ring linked, soft-start devices, components of the technical status quo and development trend, and made China's development scraper conveyor Trend.
Key words: scraper conveyor with two, components, development trends.
In recent years, with high yield and high efficiency of the rapid development of intensive mine, the coal mine in a mine to achieve a high degree of concentration of wells a production model. Face the long arm as the main transportation equipment, the scraper conveyor transport capability mainly by high yield and high efficiency of the production capacity of the mine to decide, but also determines the scraper conveyor trend of development.
1 Technology status
Since the 1980s, both at home and abroad scraper conveyor to the large volume, long distance, high-power, high-intensity, high reliability and long life direction. At present, the largest foreign Fully-face scraper conveyor to transport volume has reached 6000 t / h, installed power 4 × 800kW, distance 450 m. Domestic independent research and development of the scraper conveyor transport volume has reached 3500 t / h, installed power 3 × 700kW, distance 300 m. With God East, and other large coal base 400 m face the emergence of
