The process of grinding and milling is essential in many laboratory situations. Certain solvent-free reactions are conducted, for example, by the fine grinding of reagents together in a vessel to ensure close contact of individual particles. Grinding or milling is also essential to ensure that a sample is fully homogeneous before it is analyzed.
