我矿破碎系统中的HBG1200×4000型板式给料机传动方式为棘轮机构,由于该系统中的PEF600×900颚式破碎机破碎能力有限,因此,为破碎机提供矿石的板式给料机须能根据破碎机破碎腔中的矿石堆聚情况及时停止运行,以免因破碎机超负荷运行而造成设备事故。该系统投产以来,HBG1200×400 Since the crushing capacity of the PEF600 × 900 jaw crusher in this system is limited, the plate feeder of HBG1200 × 4000 plate feeders in mine crushing system is limited to the ratchet mechanism. Therefore, According to crusher crushing chamber in the accumulation of ore in a timely manner to stop running, so as not to overload the crusher caused by equipment accidents. Since the system was put into operation, HBG1200 × 400
