Ammtec. Values of Bond crushing work index will vary from a 8 kWht for laterite hardcap through to 22 kWht for banded iron formation to 46 kWht for fresh greenstone.
The most widely used parameter to measure ore hardness is the Bond work index Wi. Calculations involving Bonds work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index Wi C, CWi or IWi impact work index.
The Bond Low-Energy Impact test can be used to determine the Crusher Work index CWi, also known as the Impact Work Index. The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizing crushers. The open and closed sized settings for given product sizes can also be determined.
Work Index is the amount of energy required to do this work. It is a measurement of how hard the rock is and an expression of the resistance that a material has to crusher. Shown in the table below is typical Work Index, reflecting the different rock characteristics.

Abstract 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 comminution plants designing. Determining the Bond work index
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 crushing work index test sometimes called the impact work index test is noisy, and the difference you observed is perfectly reasonable. The paper by Angove amp Dunne 1997 reports a standard deviation in crushing work index tests across laboratories as 4.5.
Sep 01, 2014 Bond work index theory represents an average value on size reduction and energy usage per unit of mass, but represents a fair approximation of a comminution process. But precisely because it is an average value implies that an optimization procedure on this theory has limited value. A constant cannot be optimized.
