Yes, Google can:

"...It utilizes two vibrators that initiate a linear motion, driving particles in an uphill, downhill or horizontal direction - so water is strained down through the sand bed and below the screen deck..."

Straight from the manufacturer's literature, complete with pictures.

Just a thought, not being familiar with this specific process, are the motors mounted 90* from each other? At this position and different frequency, I would think that the material would move in a circular pattern increasing the effeciency of the dewatering. Or not.

The motors contra-rotate eccentric weights to provide true linear motion at very high 'G" forces to increase retention time and efficiency. On some models, they can be adjusted to provide elliptical, semi-elliptical, or rotary motion as needed for the product to be dried. G forces above 5 G are attainable.

Thank you all...Rockbit.....last question...if the eccencity of the vibrator make the material move away from the screen, I suppose that must be in the same aligment, meaning that the vibrator must be straighted with the direction of the material ....in some literature the vibrator are "perpendicular" to the screen...how it that work ??? please.

Excuse my english

On almost all makes and models, the vibrators are mounted at a 45 degree angle to the screen. On models I have built, I experimented with different angles and found 45 to work best, like everybody else... Re-inventing the wheel, I guess. If the vibrators are perpendicular (90 degrees) to the screen, the material will not move on its own, requiring a sloping screen to move material. When both weights are the same, true linear motion results. G forces are controlled by the weight and speed. When the weights are slightly different, semi-elliptical, or elliptical motion results. When one vibrator is shut off, orbital motion results. Independent motors are self syncronizing due to inertia.
