· The basic parts of this vibratory type sample pulverising machine are: steel grinding bowl, ring and puck. The ring and puck rotates inside the approximately 8" diameter cage at a speed around 400 RPM or fast enough to crush and pulverize rocks of up to ½" down to 400 mesh. Laboratory pulverizers sell with pneumatic or manual clamping system.
You must now grind away much of the rock that remains on your slide, but not all of it. This is the step in which most thin sections go bad. The key is: go slow, especially near the end. (Note 10/2012: I've recently developed a method that uses the lap wheels instead of the grinder for this step. It's faster, but riskier, and can give you sores on your fingers if you're not careful. I'll try ...

Grinding Samples Hand Grinding: Usually powdered XRD samples are prepared by hand grinding using a mortar and pestle. The mortar and pestle can be made out of a variety of materials such as agate, corundum, or mullite. The type you use will depend on the hardness of your sample compared to the material of the mortar and pestle and whether contamination introduced by the grinding medium will ...
This grinder is suitable for soft rock samples such as limestone. The alumina ceramic hand mill can reduce contamination, except for Cs, W and Pb. The agate hand mill and the agate ball mill introduce contamination whose level is depending on the individual device due to heterogeneity of the natural agate. The Fe hand mill introduces contamination of some siderophile elements such as Mo and W ...
Try to leave just a thin layer of rock on the slide. Save the rock chip in case you ruin the slide and need to try again! Next, back to the lap. Holding the rock side down with a few fingers in the center of the back of the slide, grind the sample thin, using 400 grit. Your goal is exactly 30 microns ( mm) of thickness across the entire sample.
