McLanahan UltraSAND

The Ultra Sand Plant is an alternative means of processing sand that offers a higher yield, improved product consistency, and superior product dryness when compared to conventional wash equipment like fine material screw washers.

McLanahan’s UltraSAND Plants (USPs) have been around for many years — they are a combination of a Sump, Pump, Hydrocyclone(s) and Dewatering Screen(s). They are typically fed <4 mesh (<5mm) material from the bottom deck of a wash screen. This discharge is nominally ≥35% solids by weight. Alternatively, they can be fed after a dry screen via a slurry box to hydrate the materials using high-pressure sprays.

With the greater separation efficiency of Hydrocyclones/Separators™, the UltraSAND Plants are proven to provide a higher product yield compared to fine material screw washers. Another advantage is a much lower moisture content from the dewatering screen, depending on the characteristics of the sand. The end result is almost immediate use of the product, steeper stacker angles for more stockpile capacity, reduced water loss, and better housekeeping. Sand equivalencies are also improved using this design of the plant.
