Get PriceJKTech Laboratory Services Bond Ball Mill Index Test (BRMWI) A Bond Ball Mill Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore. The BBMWI is a measure of the resistance of the material to crushing and grinding. It can be used to determine

Get PriceIsa Mill Test The IsaMill a transformation in grinding technology, provides high intensity fine grinding for maximising mineral liberation. The IsaMill is a grinding technology based on high intensity stirred milling, using inert media that was developed for the processing of fine grained ore bodies.

Get PriceEnergy requirements for crushing and HPGR options can now be determined in addition to AG/SAG mills, and with Mic, ball mills. The results from conducting the SMC Test are used to determine the so-called drop-weight index (DWi) which is a measure of the strength of the rock.

Get PriceJKTech offers a unique testing methodology for the quantitative characterisation of steel media wear in SAG and Ball mills. The methodology used to characterise steel media wear combines the results of two separate testing procedures that characterise both the abrasive and corrosive wear of steel media respectively, to produce one total wear prediction.

Get PriceThis Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.
