Bond’s Work

Other Tests. The so-called tumbler tests are usually used for testing material like coke, coal, iron ore pellets or tablets. They can be divided into drum tests and ball mill type tests. The latter type is used to derive both the Hardgrove Index and the Bond s Work Index, which are often used to classify the material friability as described in Sec. 3. They are generally more suited to coarse material. The Hardgrove Grindability test requires an initial size range form 595 to 1190 microns.

The prediction result is not very sensitive to the values of some of the constants. This means that for different situations, the values of the constants may be very different, as was indeed seen in the iteratively determined values in Bond s work. 

The major plays from this decade thus deal with perennial issues in Bond s work whilst also demonstrating the continuing evolution of ideology and form in the process. 

If strictly realistic and naturalistic modes of address seem outmoded, their conventions too visible, so too do the current modernist experiments that have fuelled the aesthetics of late consumer capitalism. That Bond s work attempts to negotiate this difficult historical moment is hard to deny the issues are imprinted in the content of the plays, the formal strategies and techniques through which they are mediated. Bond s own critical writing and direction of development, and the kind of success he... 

In the Conclusion, Was Anything Done , I offer a concluding reflection surveying the central issues of this study, articulating my own current re-evaluation of the significance of Bond s work. 

It is a core intention of this study to engage in a critical discoirrse appropriate to Bond s drama based principally upon closer, more subtle readings of actual plays. In so doing it is also my intention to evidence an argument for a recognition and imderstanding of politics and aesthetics in Bond s work. It represents, I believe, an important and ultimately separate development from Brecht. 

Reviewing Lear for The Times on 30 September 1971, Irving Wardle was full of praise for the play and production, reflecting the turnaround in critical reception of Bond s work at this period, following the initial and widely shared denimciation of Saved ... 

In many ways, Restoration is closest in Bond s work to The Fool [...] It shares the same affectionate but unsentimentalised fascination with the East Anglian rural working class of the eighteenth century, the same horror at the identification of justice with the rights of the landowners, the same distress at the consequences of... 

Alice is an example of the many women in Bond s work, stretching back across his entire output, who are troubled, complex and facing problematic choices. She and they are caught in a tangled, complex web of social, cultural conditions and often forced to exist within harshly oppressive political environments. They are often mothers or. 

When Xi and X2 are measured in micrometers and E in kWh/ton, K = 5Ei, where E is the Bond Work Index, defined as the energy required to reduce a unit mass of material from an infinite particle size to a size such that 80% passes a 100 pm sieve. The Bond s work index is obtained from laboratory crushing tests on the feed material. Bond s law holds reasonably well for a variety of materials undergoing coarse, medium, and fine size reduction.

Bond s Work Index A semi-empirical equation that relates the power consumption required for crushing and grinding solid particles such as rocks and ores into smaller particles. It is named after American mining engineer Fred Chester Bond (1899 1977).
