Wiley mill refers to a specific group of grinding mills manufactured under the name Thomas Scientific. The term Wiley as it relates to cuttingand/orgrinding mills is a registered trademark of Arthur H. Thomas Company. These mills prepare materials for analysis with minimal moisture loss. Well-dried samples are preferred.
The most important aspect of soil, plant and water analysis is knowing how to take representative sample. Sample integrity must be .. 1.6 Plant Grinding. a) To obtain homogeneous powders, samples are finely ground, using an Cyclone Udy Mill with stainless steel screen to pass through a 20-mesh sieve. b) Large samples.
3.3.2 Exercise care when grinding very small samples or plant material that is pubescent, deliquescent, or that has a fibrous texture. These samples are difficult to grind in Wiley mills and the operator should allow sufficient time for the sample to pass through the screen to ensure homogeneity. In these instances, experience.

Nine plant species, three each representing grass, forb, and shrub forage classes were hand composited into three mixtures so that one forage class dominated each mixture. Samples of each mixture were then allot- ted to eight treatments involving combinations of grinding through a micro-Wiley mill, soaking in sodium.

There are many effective ways to grind samples including the use of a Wiley mill, freezer mill, roller grinder, and the standard mortar and pestle. Both the . Some typical weights are 3 mg for plant leaf samples, 1 mg for animal samples, 10 mg for root samples, and anywhere from 10-70 mg for soil and sediment samples.
In the mining industry where large volumes of grinding media per mill are re- quired, media wear versus cost is a key optimization consideration. Quantifica- tion of in-plant media wear is, however, often problematic. It can be done indir- . analyses has been reported , representative sample selection could be a problem.

In this work, methods involving cryogenic grinding and planetary ball milling were evaluated for leaves comminution before pellets preparation. The particle sizes were associated to chemical sample properties.
