overflow ball mill using hydrocyclone

  • Hydrocyclone Operation Mineral Processing & Metallurgy

    Aug 06, 2015· The cyclone underflow is directed to the ball mill for further grinding Once the ore has passed through this mill it will be added back into the material that is being pumped to the cyclone for reclassification The hydrocyclone product is the overflow, which of course is finely ground rock It is this overflow which must be controlledThe traditional instrumentation in each ball mill/hydrocyclone cluster system is installed on the common system components Typically these measurements include hydrocyclone feed flow, feed density, manifold pressure, sump level, etc Determining the exact source of the oversize can be a complicated and time consuming process for a busyOptimization of hydrocyclone classification by onlineSep 01, 2016· An overfilling indicator for wet overflow discharge ball mills The grinding circuit operated a 515 m × 643 m (D × L) overflow ball mill with fourteen 038 m hydrocyclones in a closed circuit Ball charge took about 25% mill volume with aAn overfilling indicator for wet overflow ball mills

    The entrainment of fine particles in underflow of a grindingclassification hydrocyclone can cause ore overgrinding, which will lead to reductions in both metal recovery and ball mill throughput To address this problem, this paper proposed a Wshaped hydrocyclone that can effectively reduce underflow fine particle entrainment Experimental tests and numerical simulations wereHYDROCYCLONES By Richard A Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits The practical range of classification for cyclones is 40 microns to 400 microns, with some remote applications as fine as 5 microns or as coarse as 1000The Sizing & Selection of HydrocyclonesNov 01, 2004· The particle size distributions of mill feed, mill discharge and the hydrocyclone products are presented in Fig 6, Fig 7 As can be seen, the size distribution of the overflow is slightly coarser for harder material Nevertheless, the maximum size is approximately the same The control system has fulfilled the intended purposeHydrocyclone control in grinding circuits ScienceDirect

    Dec 03, 2020· The overflow of each cluster is transferred to 5–8 cleaner cells and its underflow enters a regrinding ball mill, which is in a closed circuit with these hydrocyclonesNov 13, 2020· Because such largesize mills generally form a closed circuit with hydrocyclones (no spiral classifiers with corresponding specifications are matched), the use of overflow ball mills can reduce the content of coarse particles in the mill discharge, thereby reducing the wear of the hydrocyclone 4 Autogenous MillCommon Grinding Machines Characteristics and ApplicationRatio Of Overflow To Underflow Hydrocyclone Particles Figure 2The hydrocyclone test rig used for the experiments Figure 3The hydrocyclone used under correct operation (ie the underflow was in the form of a hollow cone of angle 2030°) Figure 4Typical feed underflow and overflow particle size distributions for the fine feed at a cone force ratio = 053 and a 34 mm VFunderflow and overflow in hydrocyclone
