SGD630/220型刮板机主要适用于缓倾斜中厚煤层长壁式经济综采或高档普采的回采工作面。近几年来由于采煤工艺的发展,在放顶煤回采工作面的应用也越来越多,其主要特点是运输量大、结构强度高、适应性强。SGD630/220型刮板机中部槽上的端头所用材料一般为ZGMn13,ZGMn13高锰钢是耐
SGD630 / 220 scraper is mainly applied to slow-inclined medium-thick seam longwall economic mining or high-grade general mining face. In recent years, due to the development of coal mining technology, the application of caving coal mining face is also more and more, its main features are large amount of transportation, high structural strength and strong adaptability. SGD630 / 220-scraper machine slot on the central groove of the material used is generally ZGMn13, ZGMn13 high manganese steel is resistant
