Determining the Correct Shaker Size. The equation Force = Mass x Acceleration is the basis for sizing shakers and determining if a shaker can perform a specific shock or vibration test. The more mass you put on your shaker, the less acceleration the shaker can produce. Conversely, the less mass you put on your shaker, the more acceleration it ...

Unlike pure viscous- or elastic-based materials, Sorbothane reduces vibrations over millions of cycles without degrading. Because it's a viscoelastic material, it absorbs, isolates, and reduces vibrations simultaneously. It is capable of absorbing nearly 95% of shock energy and reducing more than 50% of vibration energy.

Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.

Key Points. A wave can be thought of as a disturbance or oscillation that travels through space-time, accompanied by a transfer of energy. The direction a wave propagates is perpendicular to the direction it oscillates for transverse waves. A wave does not move mass in the direction of propagation; it transfers energy.
