Physical Principles
- Vibration - either sinusoidal vibration or gyratory vibration.
- Sinusoidal Vibration occurs at an angled plane relative to the horizontal. The vibration is in a wave pattern determined by frequency and amplitude.
- Gyratory Vibration occurs at near level plane at low angles in a reciprocating side to side motion.
- Gravity - This physical interaction is after material is thrown from the screen causing it to fall to a lower level. Gravity also pulls the particles through the screen cloth.
- Density - The density of the material relates to material stratification.
- Electrostatic Force - This force applies to screening when particles are extremely dry or is wet.

Famous quotes containing the words physical and/or principles:
“The State never intentionally confronts a man’s sense, intellectual or moral, but only his body, his senses. It is not armed with superior wit or honesty, but with superior physical strength.”
—Henry David Thoreau (1817–1862)
“The scope of modern government in what it can and ought to accomplish for its people has been widened far beyond the principles laid down by the old “laissez faire” school of political rights, and the widening has met popular approval.”
