Quantitative Mineralogical Comparison between HPGR and

Grinding developed by a combination of high pressure grinding rolls (HPGR) followed by a ball mill (BM) was compared with a single ball mill process. The mineral characteristics of the grinding products were analyzed using a Tescan Integrated Mineralogical Analyzer (TIMA X) and X ray powder diffraction (XRD).

Comparison between Rod Mill and Ball Mill ore

2019 1 30  Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. Rod mill are usually applied to grinding the w sn ore and rare metal in the reselection or magneticore dressing plant in order to avoid the damage caused by the over crushing. 2. In the two stage grinding process, if it requires grinding the ore from 20 6mm to 1 3mm in the first stage, rod

grinding process [15, 18, 22, 28]. A comparison between ball mils and cylpebs is made in [ 42]. The speed of rotation of the mill determines three basic types of operation modes slow rotation (cascading), fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the

energy required which in this case was to grind the ore represented by the samples, from a feed size F80 of 152 mm to 80% passing 1.7 mm, and a simple adjustment procedure in case the SAG product size needed to be adjusted. Bond rod and ball mill work indices are readily converted to pinion energy for rod and ball mills but not for SAG mills.

Comparison of energy efficiency between ball mills and

Four different laboratory ball mills and stirred mills have been tested to grind seven ore samples with feed sizes ranging from 3.35 mm to 150 m. A case study on full scale operations of a 2.6 MW IsaMill replacing the existing 4 MW regrind ball mill at Kumtor Gold Mine in Kyrgyzstan is also included. This paper summarizes the major findings from these investigations.
