The simplest method of separating ore from the gangue consists of picking out the individual crystals of each. This is a very tedious process, particularly when the individual particles are small. This is a very tedious process, particularly when the individual particles are small.

It was implemented as a Fortran preprocessor on the IBM 7090 [1] [2] and was designed for large discrete event simulations. It influenced Simula. [3]
50 g of air dried coal featuring a grain size in the range between 0.6 and 1.18 mm are filled into the sample mill and a weight is put on the mill's grinding stone. After 60 rounds the grinded coal is put on a sampling sieve. Factor D equals the fraction of the coal passing through the sieve of 74 μm corresponding to 200 mesh.
The most utilized grinding mills include pin, hammer, and disk mills, but many machines are utilized for more specific processes. To maintain a high starch extraction, the grains will go through a degermination process. This process removes the germ and fiber (pericarp) first, and the endosperm is recovered in several sizes: grits, cones, meal ...
