The paper by Angove & Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4.5. The laboratory CWi value of 27.4 (metric) is almost within 4.5 units of the 22.4 value I calculated, so what you are observing is probably the natural variation in the crushing test.

Bark is fed into the shredder from a conveyor and processed with a combination of hammers and knives. Most foreign objects are crushed by the hammers, but the swiveling rotor knives will swing away if a large uncrushable object enters the unit. As an added precaution, the upper stator hammers are flex-mounted, with an overload pin for safety.

A single toggle Blake jaw crusher with 22.8 cm × 47.7 cm receiving hopper crushed gold ore at the rate of 85 t/h with closed setting at 2.54 cm and maximum opening of 3.8 cm. The work index of the ore was 13.5 kWh/t. Assuming the SG of the ore was 5.4, calculate 1. optimum frequency of the toggle cycle, 2. maximum frequency of the toggle cycle, 3.
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 to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Alternatively, the Bond Work Index (BWI) procedure was developed to accurately assess the grinding energy of brittle materials [4,5]. However, the milling energy is too low to be effective for biomass comminution. In this research, the BWI procedure was utilized with the ball–mill approach in the RIM test to evaluate torrefied biomass materials.
