A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s) Sample Requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred JKTech would stage crush the sample to minus 335 mm, as required for the Bond Ball Mill Work Index test feed

This 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 sampl These equation application methods are used to process

bond index of grinding JKTech Bond Ball Mill Index Test Typical values of Bond ball mill work index for soft oxidised ore bodies lie in the range 5-10 kWh Get Price And Support Online; Modified Bond Ball Mill Work Index Test - What is this How does a "modified bond ball mill work index" test vary from a standard

Bond Rod Mill Index Test | JKTech It is a 'locked cycle' test conducted in closed circuit with a laboratory screen Sample Requirements: A minimum of 15 kg of material crushed to nominally minus 19 mm is preferred JKTech would stage crush the sample to minus 125 mm, as required for the Bond Rod Mill Work Index test feed Get price

The JK Drop Weight Test is an industry standard for use in characterising ore under AG/SAG milling conditions The JK Drop Weight Test provides ore specific comminution parameters which are used in the JKSimMet software to analyse and/or predict crusher and AG/SAG mill performance

Energy 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

An improved method using less mass compared to the Bond Ball Mill Work Index test The JK Bond Ball Mill (JKBBM) test, is a locked cycle grindability test conducted using a standard laboratory Bond Ball Mill with the same steel ball charge and material feed size (100% passing 335 mm) as the Bond Ball Mill Work Index test

The Thirty-nine samples were submitted for the Crusher Index (Ci), SAG Power Index (SPIĀ®), Standard Bond Ball Mill Work Index (BWI) and Modified Bond Ball Mill work Index (MBI) tests The Ci, SPIĀ® and Bond Wi values of these samples show a good indication of ore hardness variability within the ore body

JKTech 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

JKTech would stage crush the sample to minus 125 mm, as required for the Bond Rod Mill Work Index test feed JKTech can prepare a representative sample, stage crushed to minus 127 mm, from a larger sample of ore if required

circuit design the work index parameter is widely used in tracking mill performance Due to the age and lack of controls for the test many laboratories have some variation in BBMWi test equipment and even processes, such as media charge or mill liner variations The JK Bond Ball Mill (JKBBM) test procedure is
