Diamond Equipment carries the Trio brand of Fine Material Sand Screws

The three functions of the Trio Sand Screw follow:

Dewatering
Washing
Classification

Water from the material that is conveyed up the inclined tub is allowed to drain to one side, rather than back through the flowing material. This provides for efficient conveyance of fine Aggregate material and for efficient water removal.

The tumbling and rolling action of the sand particles allows for the removal of any deleterious particles from the sandy material. The action of the material has the effect of breaking the moisture film of the sand particles, thus breaking the surface tension and allowing the excess moisture to drain from the material.

With adjustable overflow weirs, the Sand Screws enable operators to control the depth of the head and velocity of overflow waste water. The large overflow feed box allows for the retention of finer mesh materials or if necessary, for the removal of those particles.

As a user, you should consider four factors when sizing a fine material washer.

Tonnage
Screen Analysis
Gallonage
Silt Content

With the appropriate combination of those variables, a suitable machine is available for your application.
