Bond Work Index Procedure and Method

Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Empty the mill charge and sand into the ball try once grinding is complete Clean out the mill using a brush Put the lid on the mill Brush the sand from each Ball and place the clean Balls onto a panProcedure for determination of ball Bond work index in the ,In the determination of ball mill work index 15 kg of representative ore at 100% + 335 mm is crushed to 100% − 335 mm (Amtech, 2006) The first grinding test is started with an arbitrarily chosen number of mill revolutions At the end of each grinding cycle, the entire product is discharged from the mill and is screened on a test sieveBond Ball Mill Index Test | JKTech,The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions

A Procedure for Rapid Determination of the Bond Work Index

The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (Wi) This index is determined on a laboratory-scale using a Bond ball-mill and by Bond Work Index Tests - Grinding Solutions Ltd,Bond Ball Mill Grindability Test The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge The Work Index calculated from the testing can be used in the design and analysis of ball mill circuitsAlternative Approaches for Determination of Bond Work ,and its correlation As a fast method, the determination of the Bond index from the Hardgrove index (by calculation) is almost matching with measured Bond’s work index The Bond’s work index of the above rock samples calculated from the Hardgrove index value has shown a variation from 77 to 103 kWh/sht

Correction of Bond Ball Mill Work Index Test for Closing

The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis to another The proposed model consists of two components, the variable coefficient that is determined from a specific work index determination and a fixed exponent determined by a calibration procedureJK Bond Ball Mill Test - jktechau,Use of Work Index Since its introduction in the 1960s the Bond Ball Mill Work Index (BBMWi) parameter has been extensively used in predicting ball mill power draw Along with comminution circuit design the work index parameter is widely used in tracking mill performance Due to the age and lack of controls for the test manyBond Index Ball Mill / Rod Mill BT 100 XL - RETSCH,Bond Index Tester BT 100 XL At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 21 mm whereas Ball Mill Work Index (BWI) is used for the range from 21 mm down to 100 µm
