随着钢铁和有色金属事业发展的需要,矿石的开采和加工规模日益扩大,相反,矿石品位不断的贫化,而对精矿品位的要求越来越高,绝大部分的矿石都需要经过细磨和选矿,才能进入球团(或烧结)、冶炼。因此,就要求降低矿山选矿厂企业的经营费和减少基建投资。为了解决这一问题,首先是碎磨作业。因为磨矿作业在选矿厂中所占的经营费和投资费比例最高,
With the development of iron and steel and non-ferrous metal needs, the size of ore mining and processing is expanding. On the contrary, the grade of ore is constantly depleted, and the requirements of concentrate quality are getting higher and higher, and most of the ore needs to go through the fine Grinding and dressing, in order to enter the pellet (or sintering), smelting. Therefore, it is required to reduce operating costs of mining concentrator companies and reduce capital investment. In order to solve this problem, the first is crushing operation. Because grinding operations in the beneficiation plant accounted for the highest proportion of operating expenses and investment costs,
