The aim of this step is to ensure a smooth crushing process
Winemaking treatment The Australian Wine Research Institute
Background. The principle behind the use of cold soak is that while grape skins are in contact with juice before any alcohol is formed, anthocyanin extraction is enhanced, as is the extraction of aroma and flavour compounds, improving the overall quality of the wine produced. Cold soaking temperatures typically range from 5 to 10 degrees Celsius.
Coal analysis Wikipedia
The particle size distribution of milled coal depends partly on the rank of the coal, which determines its brittleness, and on the handling, crushing and milling it has undergone. Generally coal is utilised in furnaces and coking ovens at a certain size, so the crushability of the coal must be determined and its behaviour quantified. It is necessary to know these data before coal is

Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment

Particle-size distribution Wikipedia
Two common uses in the powder industry are wet-sieving of milled limestone and dry-sieving of milled coal. Disadvantages: many PSDs are concerned with particles too small for separation by sieving to be practical. A very fine sieve, such as 37 μm sieve, is exceedingly fragile, and it is very difficult to get material to pass through it.

6.1 Clastic Sedimentary Rocks Physical Geology
Sand ranges from 2 mm down to 0.063 mm, and its key characteristic is that it feels “sandy” or gritty between your fingers — even the finest sand grains feel that way. Silt is essentially too small for individual grains to be visible, and while sand feels sandy to your fingers, silt feels smooth to your fingers but gritty in your mouth.
