Material screening, separating, dehydrating, cooling and dryingVibration can make material discrete and distribute uniformly on the working surface.At the same time, under the action of gravity, impacting force, friction and inertia forces,vibrating machines can perform screening, separating, dehydrating, cooling, etc.3. Material grinding, work piece cleaning and polishingVibration can make materials crack and crackles spread rapidly inside thematerials. It can also intensify the friction and impact among grinding （polishing,cleaning） medium and particles of processed material or work pieces to performmaterial work piece） grinding, cleaning, casting component shaking, workpiecepolishing, etc.4. Discrete material shaping and compactingVibration reduces the coefficient of friction inside material remarkably so that"flowability" is increased, and makes material shaping easily and more compact.5. Soil, sand and gravel compacting, concrete vibrating, pile driving anddrawingVibration can reduce internal friction force that soils, gravels and other mixedmaterials exert on penetrating objects （such as piles and pipes） so that soil and gravelcompacting process, concrete vibrating process, and pile driving and drawing processescan be performed effectively. Hence, the human labor intensity can be reducedremarkably.6. Instrument, machine and their components testingVibration can also be used to perform vibration test of machine components. Vibratingtesting machines and vibrating measuring insmanents are widely used to measureparameters of measuring insmunents, machines and their components. Vibration principleis also used to perform dynamic balance of rotating components.
