Mechanical Screening - Physical Principles

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:

    My vocabulary dwells deep in my mind and needs paper to wriggle out into the physical zone. Spontaneous eloquence seems to me a miracle. I have rewritten—often several times—every word I have ever published. My pencils outlast their erasers.
    Vladimir Nabokov (1899–1977)

    The honor my country shall never be stained by an apology from me for the statement of truth and the performance of duty; nor can I give any explanation of my official acts except such as is due to integrity and justice and consistent with the principles on which our institutions have been framed.
    Andrew Jackson (1767–1845)
