    Stage 3 Granular material is poured from the top of the hole. The water from the lower jet is transferred to the jet at the top of the vibrating unit. This water carries the granular material down the hole. Stage 4 The vibrating unit is gradually raised in about 0.3 m lifts and held vibrating for about 30s at each lift. This process compacts

  • Air Swept MillMineral Processing Metallurgy

    In an air-swept mill the body of which does not differ significantly in general design from a trunnion overflow mill a powerful stream of air is passed through the mill and removes the finer particles produced by the grinding process. This stream of powder-laden air is then passed through the classifier and the "oversize" material rejected by the classifier is returned to the mill with

  • Dilatancy (granular material)Infogalactic the

    Dilatancy is the volume change observed in granular materials when they are subjected to shear deformations. This effect was first described scientifically by Osborne Reynolds in 1885/1886 and is also known as Reynolds dilatancy.. Unlike most other solid materials the tendency of a compacted granular material is to dilate (expand in volume) as it is sheared.

    The hydraulic classifier is the key to the wet frac sand process as it provides critical fine separation in preparing the feed for the dry plant. Hydraulic classifiers determine which separation goes into waste and which goes into frac sand.
