  • 12 LABORATORY SAMPLE PREPARATION

    2021-6-25 · When a sample is dry ashed, a fine residue (ash) is often formed. The small particles in the residue are resuspended readily by any air flow over the sample. Air flows are generated by changes in temperature (e.g., opening the furnace while it is hot) or by passing a stream of gas over the sample during heating to assist in combustion.CHAPTER 20: SIZE REDUCTION EQUIPMENT FOR SIZE ,2011-12-27 · • Coarse grinding has RRs below 8:1 • Fine grinding can exceed 100:1 • Grinding of coarse particles in which the increase in surface area per unit mass is relatively small, Kick's Law is a reasonable approximation • Rittinger’s law States that the energy required for
