Apr 21, 2016· The fine ore is taken from the bin via conveyor and discharged into a 7 foot by 7 foot ball mill. Water, lime and cyanide are added at this point. The ball mill discharge is pumped to a hydrocyclone with the underflow going back to the ball mill and the overflow feeding a 5 foot by 5 foot ball mill. Aprende más

In order to investigate the breakage behavior of the feed in industrial secondary ball mills, the breakage characteristics of fine magnetite were analyzed. Magnetite particle breakage produces a bimodal particle size distribution that is consistent with the typical breakage characteristics of abrasion. The secondary ball mill can increase the surface area by reducing the diameter of steel ...

Abstract. The application of vertical mills in regrind circuits is consolidated. This type of mill is now attracting interest in primary grinding applications, due to its higher efficiency when compared to ball mills, which are usually used at this stage. In this study, a coarse sample of iron ore was tested in a pilot scale grinding circuit ...
