Air-pressure mills are used for very fine milling (to a grain size of 0.001–0.05 mm). Ground material is introduced into ejectors facing one another. Compressed air under a pressure of 0.4—0.8 meganewton per sq m (40–80 kilograms-force per sq cm), super-heated steam, or hot gaseous combustion products are introduced into the ejectors.
where i is the ith size fraction (2–8, 0.25–2, and 0.053–0.25 mm); dry soil aggregate (DSA i) is the oven-dried mass of total, non-dispersed aggregates collected on each sieve; sand is the oven-dried mass of sand collected after dispersal in the hexametaphosphate solution on the 0.053 mm sieve; Total Soil is the oven-dried mass of soil (50 g) for aggregate separation.

Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety

The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns (0.1 mm). The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 – 70% by weight.
