近年来,随着包钢白云鄂博铁矿开采规模的不断扩大,矿石与岩石的剥采量随之增加.岩石的倒装量很大。铁矿根据生产需求,2002～2003年先后引进了2台大型振动放矿机进行岩石的二次转载,转载能力可达到450万 t/a,进一步提高了排岩效率,满足了生产需求。然而大型振动放矿机在使用中机车挡料板出现了问题,机车挡料板是为了减轻装车过程中矿岩对基架的冲击,并有效将矿岩弹回电机 In recent years, with the continuous expansion of the mining scale of the Bayan Obo Iron Ore Mine in Baotou Steel, the amount of ore and rock stripping increased with the large amount of rock-in-rock. According to the demand of production, from 2002 to 2003, two large-scale vibrating ore mills were successively introduced into the iron ore for secondary reloading. The reloading capacity can reach 4.5 million t / a, which further improves the rock-rowing efficiency and meets the production needs. However, the use of large vibrating leveler locomotive material blocking board problems, locomotive material board is to reduce the loading process of rock ore on the pedestal impact, and the effective recovery of ore rock spring motor
