Bond Ball Mill Work Index GTEK Bond Ball Mill Work Index is used for determine the grindability of materials and help to choose the most suitable type and model of grinding equipment Ask For Quote Donwload Find details in the options below Photo.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 circuits The test requires a minimum of 10kg of sample that has been stage crushed to 100 passing size of 3 35 mm.

Comparative bond ball mill work index comparative bond ball mill work index a bond ball mill work index test is a standard test for determining the ball mill work index of a sample of ore it was developed by fred bond in 1952 and modified in 1961 jkmrc co 2006 this index is widely used in the mineral industry for comparing the resistance of.
The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave shaped design 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 2 1 mm whereas Ball Mill Work.
The grinding jar for the Bond Index Rod Mill is 12 x 24 in sie and has a wave shaped design 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 sie determination in a sie range from 25 mm down to 2 1 mm whereas Ball Mill Work.
The Bond rod mill work index is not as common as the Bond ball mill work index and there are two different variations on the mill apparatus The SAGMILLING COM models expect a mill with a wave liner and is not compatible with mills using smooth liners.
A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO 2006)This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy required.
Ball Mill Design Power Calculation 2018 6 21 The basic parameters used in ball mill design (power calculations) rod mill or any tumbling mill sizing are material to be ground characteristics Bond Work Index bulk density specific density desired mill tonnage capacity DTPH operating solids or pulp density feed size as F80 and.
A bond ball mill work index is then performed on the mill product for the design of sagball mill circuits this is important because it was found that there was a kwht higher ball mill work index if the mm ball mill test feed size is obtained by sag mill grinding.
Jan 01 1989 INTRODUCTION The energy consumption for grinding according to Bond (1961) is deter mined by the formula 10 10 (I) The work index is determined by grinding experiments carried out in a labo ratory Bond ball mill Based on the results of grinding experiments numerical values of the work index Wi are calculated according to the formula.
21 CONCLUSIONS Continued In the present work equations were also derived giving zthe ball mill power drawP as a function of its dimensions internal mill diameter D and length L zthe ball mill power drawP as a function of the feed D f (mm) and the product size d (mm) the Bond work index w i (kWh short ton) and the mill throughput T (short ton h) zthe ball mill dimensions (D and L) when.
In this regard calculation of work index of limestone made by standard Bond grindability test Ball mill was employed to conduct the grinding test of seven different samples Among all seven samples collected from the different faces of quarry Bond work index of limestone Face4A results less than 20kwh t remaining 6 samples are marked as hard.
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 10 kg of material crushed to nominally minus 10 mm is preferred JKTech would stage crush the sample to minus 3 35 mm as required for the Bond Ball Mill Work Index test feed.
Aug 10 2017 An alternative mill ball charge is proposed that closely approximates Bond's original total ball mass number of balls and ball surface area Results of 30 Bond Work index tests of six pure materials (calcite magnesite labradorite (feldspar) quartz andalusite and glass) using closing screen apertures (P 1 ) values of 500 250 125 90 and.
