随着我国钢铁工业的迅速发展,新的矿产资源大规模地被开发利用,入选的矿石量与年俱增,促使我国选矿机械向大型化发展。选矿机械大型化将使我国选矿厂由过去的中、小型设备组成的多系列,发展为大型设备的少数系列,可以极大地提高我国选矿厂的装备水平。以齐大山铁矿扩建工程为例,要扩建一座1700～2200万吨的大型选矿厂,若以φ5.5×1.8米湿式自磨机装备选矿厂,则需要40～52个系列;若以φ7.5×2.5米湿式自磨机,则需要17～22个系列;若以φ10×3.6米湿式自
With the rapid development of China’s steel industry, new mineral resources have been developed and utilized on a large scale. The amount of selected ore has been increasing year by year, prompting the large-scale development of beneficiation machinery in our country. Large-scale beneficiation machinery will make our dressing plant from the past, composed of small and medium-sized multi-series, the development of a small series of large equipment, can greatly enhance the level of equipment in our dressing plant. Taking the Qidashan iron ore expansion project as an example, it is necessary to expand a large scale beneficiation plant 1700 ~ 2200 tons. If the ore dressing plant is equipped with a φ5.5 × 1.8 meters wet self-grinding mill, 40 to 52 series are required; if φ7 .5 × 2.5 m wet self-mill, you need 17 to 22 series; if φ10 × 3.6 m wet from the
