This means that the benefits of both vibration types are combined in a horizontal screen. Horizontal screens have a stroke range of 14–20 mm and typically run at a stroke of 16–18 mm and a spinning speed of 750 rpm. Between 0.2 and 0.25 meters per second, materials move through the screening medium.

Originally posted by: jliechty Recently, my monitor, a 19 inch Philips 109B2, has been exhibiting a strange behavior in a subtle way. The image appears to "flicker," or more appropriately, vibrate; this happens (though less noticeably) even when the resolution is lower and the refresh rate is at 85Hz or above (normally I run 1600x1200@75Hz).
