通过预选方法在矿石进入选厂的磨矿作业前预先抛弃部分不合格的矿石和废石,不仅能提高选厂的入选矿石品位而且有利于提高整个选厂的技术经济指标,还能节省能源,同时还能扩大对某些低品位矿石的开发范围,因此矿石的预选已成为今日选矿中人们注目的问题。本文着重介绍了近年来在预选设备方面的进展。重介质分选设备近年来在分选小于20毫米矿石仍然是一种有效的预选设备。TRI-FLO重介质涡流旋流分选器近几年在意
Through the preselection method, some unqualified ore and waste rock are discarded in advance before the ore enters the ore dressing plant, which not only improves the selected ore grade of the beneficiation plant but also improves the technical and economic indexes of the entire beneficiation plant as well as saves energy, While also expanding the scope of the development of some low-grade ore, ore pre-selection has become the focus of attention today in mineral processing. This article highlights recent advances in pre-selected equipment. Heavy media sorting equipment in the recent sorting of less than 20 mm ore is still an effective pre-selected equipment.
