This method of separation of particles from a mixture based on the difference in size of particles is known as sieving. It uses sieve plates for separation of coarse particles from finer particles. Sieve plates have meshed or perforated bottoms which allow only particles of a specific size to pass through it.

Wear resistant steel is used as construction material of the hydro cyclones. Depending on the flowrate a single hydro-cyclone or several hydro-cyclones may be installed in a parallel feed arrangement as shown in Fig. 5.1. Due to rather high flow rates and coarse separation cut, large diameter hydro-cyclones are used, depending on flow …

The mechanical liquid/liquid separations are based on differences of the liquid densities (e.g., oil–water separation). The solid/air separation is based on different densities of the materials (e.g., particles in cyclone) and on the fact that solids, unlike gases, cannot pass through fine-meshed (woven) textiles.
