Crushing or grinding of samples is necessary because it is a rule typically required and highly important to decrease the molecule or particle size of solid samples. Since these operations tend to alter the composition of the sample, the particle size should be reduced no more than is required for consistency.
A sample-drying room (20 m 2) is used both for short-term storage and for drying of samples. Archives of samples are stored in a separate area of the facility. Crushing and Grinding. The coal sample, as received from the field, consists of 3 to 15 kg of material that first is reduced to a particle size of 2 to 4 mm (5 to 10 mesh) in a jaw crusher.

Moisture loss is also observed when samples containing occluded water are ground and crushed. The process ruptures some of the cavities, and exposes the water to evaporation. More com - monly, the grinding process results in an increase in moisture content due to an increase in surface area available for absorption of atmospheric water.
