The handpicked fiber bundles were ground for 5, 15, or 30 min in a high-energy vibratory ball mill (Model 8000, SPEX Industries, Inc.) with or without deionized water. The wet samples were oven-dried for 24 h at 70 °C. Asbestos fibers were prepared and handled inside the fume hood to minimize asbestos exposure.

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...
