在过去几年中,在中欧选矿领域中应用技术的不断发展集中体现在物料的回收利用方面,如充填物料、废渣、废石、废料和碎屑以及污染土壤等的回收利用。在水泥加工领域,溶渣以及冶金砂料主要用高压料层辊磨机粉碎。这种设备还用于铁矿石以及铬矿石的再磨,以生产球团作业的给料。 In the past few years, the continuous development of applied technologies in the field of beneficiation in Central Europe has focused on the recycling of materials such as filling materials, waste residue, waste rock, waste and debris, and recycling of contaminated soils. In the field of cement processing, slag and metallurgical sand are mainly crushed by a high-pressure bed roller mill. This equipment is also used for the regrinding of iron ore and chrome ore to produce pellet-fed feedstock.
