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 properties of materials . Literature review on impact crusher performance in relation to machine configuration and operational conditions, by experimental work and mathematical ...
FIGURE 1: BOND CRUSHING WORK INDEX v. UNCONFINED COMPRESSIVE STRENGTH 0 100 200 300 400 UCS, MPa 10 20 30 40 50 WiC (metric) The scatter of the points in Figure 1 indicates no correlation between crushing work index and UCS.
The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial ... Laboratory Jaw Crusher - 911Metallurgist
crusher were compared with those of the Bond crushing energies (estimated from the Bond crushability index) of the rocks. Also, the effect of the Bond crushability index on the estimated crushing energy of the rocks was studied. Materials and methods In this work, nine different rock specimens were obtained from some mines in Iran.
Jan 01, 2016 The models for determining the power required for operating jaw crushers have mostly been derived using Bond’s work index. While these gave satisfactory estimations of power, it must be remembered that Bond’s expression was derived using a tumbling mill where the forces of comminution are not quite the same as that in jaw crushers ...
Bond work index reduction In applications where the HPGR is followed by ball milling, the induced micro fractures generally result in a reduction of the Bond Work Index. For most ores this reduction ranges between 10-25%. Obviously this allows for grinding at either an …
Bond Crusher Work Index. Bauxite crushing bond work index – rock crusher and the crusher work index in kwhton is a function of the material’s impact strength and is defined by an argillite type of rock which has a work index of 165 bond crushing work index. Bond Crushing Work Index Of Copper Slag
Crushing in Mineral Processing Mar 19, 2017 Bond’s impact method comes from a double mirrored pendulum impact crusher test on 51mm (3″ and 2″) square rock pieces. The resulting consumed power is calculated using Bond’s standard equation .

Abrasive Rock Hard amp NonAbrasive Rock Medium amp Abrasive Rock Medium amp NonAbrasive Rock Soft amp Abrasive Rock BOND WORK INDEX KWHT LOS ANGELES VALUE UCS MPa The hardness of a material is a major consideration in the selection of the type of crusher to use Hardness is a factor in the amount of wear and tear crushers and screens
Jan 01, 2016 The Bond work index of the unknown ore can then be estimated from the equality given in Equation . (3.49) W iU 1 P U − 1 F U ≈ W iREF 1 P REF − 1 F REF where. W iU = Bond work index of the unknown ore. W i REF = Bond work index of the reference ore. F U, P U = F 80 and P 80 of the unknown ore. F REF, P REF = F 80 and P 80 of the reference ore
