This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on ‘around the world sample’ You can find the SG of each mineral samples on the other table Show 10 25 50 100 entries Source 1 Source 2 Source 3 Source 3 Ball mill work index adjustment The Bond ball mill work index test requires the operator to select an appropriate screen size to "close" the test The procedure states that the closing screen size should be such that the product size of the test is the same as the expected product size of Ball mill work index adjustment The Work Index (BWi) is calculated according to Fred Bond’s Equation Bond Work Index for Testing Procedure Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing Bond Work Index Procedure and Method 911
It is commonly known that one must run the Bond ball mill work index test such you pick a closing mesh to give a P80 close to desired grind size This is because work index frequently changes as a function of the product size in comminution If target grind size during a project is changed, or ifThe ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 336 mm (6 mesh) to product size in the range of 45150 µm (325100 mesh), thus determining the ball mill work index (Wi B or BWi) The work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of interest, or by chaining individual work index calculations using multiple laboratory work index Bond Work Index an overview ScienceDirect Topicsball mill output per tonpastoriezelem E is the energy (kilowatthours per metric or short ton) W is the work index measured in a laboratory ball mill (kilowatthours per metric or short ton) P 80 is the mill circuit product size in micrometers F 80 is the mill circuit feed size in micrometers Rod millwork index measured in a laboratory ball mill for rice
The Bond Work Index (BWI or W i) is defined as the calculated specific energy (kW h/t) applied in reducing material of infinite particle size to 80% passing 100 μm The higher the value for W i, the more energy is required to grind a material in a ball mill , Use this online formula to calculate a Ball Mill, Rod Mill or SAG Mill Operating Work Index Based on Fred Bond’s work you can estimate the energy used into your grinding circuit This is the most accurate and informative method, but much of the data necessary for its application is not yet availableCalculate a Mill's Operating Work Index 911 This is because work index frequently changes as a function of the product size in comminution If target grind size during a project is changed, or if the test is run at the wrong product size, then it is necessarily to provide a correction The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basisCorrection of Bond Ball Mill Work Index Test for Closing
The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index The test is a 'lockedcycle' test where ground product is removed from test cycles and replaced by fresh feed The work index W i using a novel ring mill, a laboratory ball mill, a labora tory rod mill and the semi continuous process using the same rod mill as described below In all cases the min eral sample is crushed and screened to pass a predeter mined size 35 or 4 mm The feed sample undergoes aA New Approach to the Calculation of Work Index and 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 stagecrushed to 100% passing size of Bond Work Index Tests Grinding Solutions Ltd
