Bond Impact Crushing Work Index
The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of (PDF) Modelling the crushingsizing procedure of ,The models give the cumulative fraction passing P as a function of the product x and the openside setting (discharge opening) Oss of the gyratory crusher. The CORRELATION BETWEEN BOND WORK INDEX AND ,The Bond work index is regarded as one of the crushing resistance; it can therefore be presumed that the Bond work index is correlated to the mechanical
Bond Work Index an overview ScienceDirect Topics
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required Summary of results from Bond crushability and impact ,The traditional Bond work index proposed by F.C. Bond over 60 years ago is still today a useful tool for characterizing material crushability and grindability in the minerals industry.Bond Impact Crushing Work Index ,The Pendulum Tester / Bond Impact Crushing Work Index Tester.

Gyratory and Cone Crusher ScienceDirect
A gyratory crusher received iron ore from the mines at 1.5 m top size. The work index of the ore was determined as 12.5 kWh/t. The height of the bowl was 9.75 m and it was required to produce 300 t/h of crushed material at 175 rpm. Calculate the required crusher set to satisfy the crusher throughput. 5.12Gyratory Crusher an overview ScienceDirect Topics,Gyratory and Cone Crusher. In Mineral Processing Design and Operations (Second Edition). 5.1 Introduction. Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher [1].The smaller form is described as a cone crusher. The larger crushers are normally known as primary Superior™ MKIII Series primary gyratory crushers Fruitful ,Superior™ MKIII Series is the third generation of the Superior™ primary gyratory crushers. The latest generation is again better, more efficient, safer, and simpler than the previous one. Superior™ crushers are most often used in mining operations. The product family was developed especially to meet the needs of customers facing ever

The traditional impact work index (Wi) proposed by Fred Bond over 60 year ago is still used today in characterizing material crushability. However, more Comminution testing JKTech University of Queensland,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 3.35 mm, as required for the Bond Ball Mill Work Index test feed.C.A. Rowland,test work. Bond work indices, obtained from benchscale or pilot plant crushability and grindability tests are used in the fol lowing Bond equation (Bond, 1960) to determine the energy required to produce the required size reduction (1 ) Where W is the power requirements (kWh/st), Wi is the work index determined from comminution test ing,

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 3.35 mm, as required for the Bond Ball Mill Work Index test feed.Determining the Bond Efficiency of industrial grinding ,Work Index, Work Index Efficiency, Bond Work Index testing 4.INTRODUCTION AND BACKGROUND The Bond method allows for quantification and comparison of relative energy efficiencies of most industrial comminution circuits. It is an essential tool for managing the important business (cost) of grinding. For early analyses Comparison of UCS to Bond Work Indices,None of the individual Work Index versus UCS graphs displayed a correlation with Unconfined Compressive Strength. Figure 7 shows an attempt to relate the sum of all Bond Work Indices to the UCS. The Yaxis on this graph measures Wi C+Wi RM+Wi BM. The sum of the Bond Work Indices fails to show a relationship to UCS.

The work index indicates the resistance of the material to grinding.
