ABSTRACT:
A mobile Sand Dryer is disclosed. This dryer is substantially made up of two portions. The first portion of the Sand Dryer is a wet sand tank. This tank is essentially divided into two distinct portions; an upper wet sand holding chamber and a lower sand drying chamber. The two chambers are divided by a grate. The upper wet sand holding chamber is supplied with a removable lid as well as a fan which may be used to create a vacuum in the chamber. The lower sand drying chamber is supplied with a propane burner and a hopper bottom. During use wet sand is placed in the upper wet sand drying chamber via the removable lid. The wet sand collects on the steel grate as it is placed into the chamber. Upon ignition of the burner and the fan the vacuum crated by the fan tends to draw the heat and moisture from the sand up and out the top of the chamber. As the sand on the grate is dried it falls through the grate before finally be moved via a vacuum tube to the second chamber. The second chamber is essentially used as dry sand storage chamber where dried sand may be kept until such as it is needed.
