Abstract
An improved apparatus and methods for recovering abrasive from an abrasive-laden fluid are shown and described. An abrasive-laden fluid handling device is coupled to a catcher tank to collect abrasive-laden fluid and transport it to a hydro-classifier. Wet recovered abrasive is discharged from the hydro-classifier and transferred to a de-watering device. The de-watering device removes water from the abrasive by decanting fluid and via use of an air eduction system. De-watered abrasive is then ejected from the de-watering device to a dryer unit, to be further dried and processed for reuse.
