The Crusher Work Index in kWh ton is a function of the material’s impact strength and is defined by an argillite type of rock, which has a work index of 16.5 bond crushing work index equipment.
The crushing work index (CWi), estimated on the basis of the twinpendulum test, has been proposed by Fred Bond and accumulates a long track record in predicting the performance of crushing.
Corrugated cardboard is an ecological material, mainly because, in addition to virgin cellulose fibers also the fibers recovered during recycling process are used in its production. However, the use of recycled fibers causes slight deterioration of the mechanical properties of the corrugated board. In addition, converting processes such as printing, die-cutting, lamination, etc. cause micro.
The Bond low-energy impact crushing work index ( rmally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test The test is a 'per-specimen' test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus.

Background objectives A large number of labourers work in the stone-crushing industry in India. Many of these workers are also exposed to high levels of particulate matter in their homes from the use of biomass fuels. As part of our investigations to examine the health of these workers we characterised their exposure to respirable crystalline silica and a number of other particulate matter.
Comparison between bond crushing energy and fracture rocks were studied and the energies consumed by the crusher were compared to those of the Bond comminution energy estimated from the Bond index. There is considerable difference between Bond crushing energy and work done by the jaw crusher for rocks.

As a basic rule, impact crushing is suitable for rocks with a low work index ( 12) as well as low silica ( 20 ) and moisture levels ( 5 ). Rocks with these characteristics are soft and non-abrasive, and easily broken within the crushing chamber, keeping wear rates at a minimum, and producing high reduction ratios with a better-shaped end product.
Ammtec. Values of Bond crushing work index will vary from a 8 kWh t for laterite hardcap through to 22 kWh t for banded iron formation to 46 kWh t for fresh greenstone.
Oct 07, 2021 A series of one-dimensional dynamic compaction tests were conducted on coral sands with different impact energies. Effects of impact energy on the compressibility and crushing of coral sands were assessed in terms of the evolutions of axial deformation, particle size distribution, void ratio, relative breakage index and fractal dimension. The test results indicate that the axial deformation of.
