Sand sized particles
Suspension: Smaller, dust-sized particles can become suspended in the wind column and potentially carried long distances until the wind calms enough to deposit them. Saltation : Larger, sand-sized particles skip and bounce along the Earth's surface, experiencing brief periods of suspension alternating with impacts on the surface.Specifically, according to the Wentworth grade scale ( PDF version) gravel-sized particles have a nominal diameter of 2 mm; sand-sized particles have nominal diameters from <2 mm to >62.5 µm; silt-sized particles have nominal diameters from <62.5 µm to >4 µm; and clay is < 4 µm.

Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. Sand, as you may guess, forms sandstone. Sandstone is medium-grained, meaning its fragments are between 1/16 mm and 2 mm. Silt forms fine-grained siltstone, with fragments between …Coarse-grained soils are divided into sands, in which over 50 percent of the coarse fraction is composed of “sand-size” particles and gravels, in which over 50 percent of the coarse fraction is composed of Gravel-size particles. The break between sand- and gravel-size particles was established at ¼ “diameter” (or #4 sieve).Abstract.

Wind more easily picks up particles on ground that has been disturbed, such as a construction site or a sand dune. Just like flowing water, wind transports particles as both bed load and suspended load. For wind, bed load is made of sand-sized particles, many of which move by saltation (Figure below).
