In ASTM standards, sieve diameter sizes are measured in inches, whereas in ISO/BS standards millimetres are used. There is a slight difference between 8in and 200mm, or 12in and 300mm diameter. In reality, 8in is 203mm and 12in is 305mm.
Roll this ball out until it reaches 3.2 mm (1/8 in.) in diameter and repeat the procedure until the thread is crumbling and cannot be rolled back into a ball. Repeat steps 4 through 6 until approximately 6 g of material is available (see Fig. 8 of the attached ASTM guideline).
This paper presents the breakage properties of five different porous materials based on a kinetic model, which was commonly used in the cement industry. For this purpose, firstly, standard Bond's grindability tests were made for five porous samples. Secondly, eight different mono-size fractions were ground between 1.7 mm and 0.106 mm formed by a V2 sieve series.

ASTM A302 Grade C Mn-Mo-Ni Steel. ASTM A302 grade C is a type of ASTM A302 alloy steel. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. It has the highest ductility compared to the other variants of ASTM A302 alloy steel. The graph bars on the material properties cards below compare ASTM A302 grade C ...
In particular, the Bond work index (wi) is considered a critical parameter at an industrial scale, provided that power consumption in comminution operations accounts for up to 40% of operational costs. Despite this, the variability of wi when performing the ball mill Bond's standard test is not always understood enough.
were conducted; standard Bond tests to determine ore grindability and work indices, batch grinding tests to determine parameters for breakage and selection functions, and standard ball mill tests for mineral liberation characterization by an automated mineral liberation analyzer (MLA).The tests were conducted in a size range from 0.063 to 2 mm.

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5 ). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
