Silica sand particles are sized and processed for use as frac using a vibrating screen. The sand is fed to the vibrating screen at a rate of 12-15 tons per hour. The dry urethane screen panels size the sand between 40 US mesh and 20 US mesh. The panels are specially designed for an extended life cycle with the abrasive silica sand.
Material enters a feed box and then falls onto the screen’s surface, which is mounted on a downhill angle close to the angle of repose of the silica sand. This promotes better particle separation and high speed screening. A full width vibratory drive motor is used for the screen frame and the screen panel surfaces. The machine is totally enclosed for dust tight operation with hinged covers on the top and sides of the machine to allow for routine inspection and screen panel change over.
