Mixer/Mill Applications

  • Learn how the Mixer/Mill can assist your sample preparation:

    1. Production of Nano-Crystalline Oxidized Ceramics with High-Energy Ball Milling: Analysing particle size effects in nanocrystalline materials requires a technique in which one can adjust the particle size. In this study various nano-crystalline materials were produced using a ball mill (8000M Mixer/Mill®, SPEX SamplePrep; equipped with alumina and zirconia vials). Ball milling is particularly suitable for this task as it is easy to use and allows the grinding of a relatively large amount of material as well as a large variety of different materials.
    2. Feedstuffs Analysis – Crude Fat (Hexane Extractables): Principle Lipids are recovered by simultaneous milling and extraction with hexane in a sealed ball mill vial. Scope The method is applicable to feedstuffs, corn germ and other components derived from the milling of corn.
    3. Mechanical Alloying with the Mixer/Mill: SPEX SamplePrep 8000-series Mixer/Mills are routinely used for pulverizing rocks, minerals, sand, cement, slag, ceramics, catalyst supports, and hundreds of other brittles, often hard samples. Typically, samples are ground then blended with binder before being pressed into sample discs for XRF analysis or dissolved into solution for ICP analysis. The vigorous motion of the clamp is also excellent for making emulsions, such as paints, inks and pharmaceuticals.
    4. Principles of Sample Preparation by Grinding or Comminution: Sample preparation is the process where a representative piece of material, chemical or substance is extracted from a larger amount, bulk, or batch for subsequent analysis. Representative samples are selected to accurately reflect the larger group and represent the characteristics of the whole material. Ideally representative samples are homogeneous or similar in nature, but when that is not possible, the best attempts must be made to achieve samples which represent the majority of the characteristics of the larger grouping.
