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:
“A more problematic example is the parallel between the increasingly abstract and insubstantial picture of the physical universe which modern physics has given us and the popularity of abstract and non-representational forms of art and poetry. In each case the representation of reality is increasingly removed from the picture which is immediately presented to us by our senses.”
—Harvey Brooks (b. 1915)
“To abandon oneself to principles is really to die—and to die for an impossible love which is the contrary of love.”
—Albert Camus (1913–1960)
