8-8-2020 · Grain size scale, in sedimentology, division of a continuous range of particle sizes into a series of discrete groups.Several such scales have been devised for the purpose of standardizing terms and providing a basis for statistical analysis. On most scales, the finest particles are designated clay, followed by silt, sand, granules, gravel, pebbles, cobbles, and boulders.

Abrasive grade / Grit sizeDeze pagina vertalen

How closely a product is coated - i.e. how many sand grains there are per m2 varies. Typically 50 to 75% of the surface is covered with grain. The coarse grit sizes are usually scattered more open than the finer. A densely littered product immediately gives a good performance at startup. A more open coat can give a better effect over time.
