In recent years, a new type of wear-resistant material——wear-resistant ceramic liner has replaced the traditional manganese steel lining, being widely used in ore terminals. The Kingcera NMC series of wear-resistant ceramic is widely used in wear-out machines as forwarding station hoppers, bucket wheel machines, belt rollers. According to practical experiences in large ore terminals like Qingdao Cargo, Rizhao Cargo, Yingkou Cargo, Jingtang Cargo, Caofeidian, Kingcera wear-resistant ceramic has resolved the wear out problems and reduced replacement, the service life is five times longer the same thickness manganese steel, which has reduced the labor cost and raised the working efficiency.
