Abstract: This paper aims to investigate the features of particles passing through screen in a new Three Product Hydrocyclone Screen (TPHS). The result shows that with the increasing feed concentration, particles reporting to overflow, underflow and screen underflow become coarser, finer and bigger, respectively; as the feed pressure increases, those first increases then decreases, rises and falls, respectively; with the increase of spigot size, those become coarser, bigger and stable, respectively. Further, the optimum feed concentration, feed pressure and spigot size were 120 g/l, 0.07 MPa and 17.50 mm, respectively. Moreover, as the feed concentration, feed pressure or spigot diameter increases, both the average particle size and concentration of fluid permeating screen raises, while the permeating throughput decreases as either the increasing feed concentration or the decreasing feed pressure and spigot diameter. Besides, the deeper axial depth of cylindrical screen, the less particles penetrating screen.

Keywords: TPHS; three product hydrocyclone screen; particle passing through screen; particle classification; process feature.
