Experimental Study on Optimization of Grinding Media in a Concentrator in Southwest China
摘要
Abstract
Aiming to address the issues of insufficient grinding capacity,poor targeting of grinding media ratio,and failure to meet production requirements in the primary grinding system of a concentrator in Southwest China,an optimization study on the grinding media ratio was conducted based on Duan's semi-theoretical ball size formula.The results showed that the optimal initial ball size scheme is φ90∶φ80∶φ60∶φ40=15∶20∶40∶25.Under this initial ball loading regime,the content of the+0.2 mm coarse fraction decreased by 4.1 percentage points,the grinding fineness of the 0.2～0.038 mm fraction increased by 2.21 percentage points,and the grinding efficiency was significantly improved.关键词
