milling the grinding of solid samples is essential to ensure precise analysis. It is important that the grinding leads to the homogeneity and desired fineness of the sample. the type of mill to be used depends on the properties of the substance and the quantity of the sample. for example, brittle materials are ground with a beater, fibrous jan 31, 2021 the wet milling process involves using water to break down grains prior to milling. this allows the individual parts of the grain to separate from one another for easier harvesting. the wet mill process is a common method of harvesting grain for food components, but dry milling is more common for flour or ethanol production.
