How It's Made Vibrating Mining Screens

Mines and quarries use crushers to break  down raw material those raw materials go  through a vibrating screen to separate  the particles by size the vibrations  caused the smaller pieces to fall  through the screen.

While the larger  pieces remain on top this limestone  quarry uses a vibrating screen with  three decks the top deck filters out the  largest stones which will be used to  make concrete the second deck collects  half-inch rocks they'll be used to make  asphalt the final deck gathers the  smallest materials to produce limestone  sand.

The screen mesh is made from steel  wire this steel contains carbon making  it more durable than regular steel a  pair of wheel dies crimp it into a wave  pattern the diameter of the wire and  crimp pattern determine the shape and  size of the screen mesh openings workers  can change the dyes to crimp different  patterns  the machine cuts the crimp wire to a  specific length
