  • An _______ separates light and heavy materials.
    air classifier
  • Which connector shows the next step after the first one?
    Next
  • What happens in the final air classifier?
    Plastic rises while wet paper falls
  • The mixture becomes a _______ after water sprays.
    wetted mixture
  • Which materials are separated in the first air classifier?
    High density and low density materials
  • The waste is shredded in a ______.
    hammer mill
  • Why is magnetism used to remove metals?
    Because it attracts ferrous metals like iron and steel
  • density (hustota)
    How heavy or light a material is compared to its size
  • Paper and plastic are separated because they have different _______.
    density
  • A _______ removes organic matter.
    rotating drum
  • Which connector should we use at the last stage?
    Finally
  • What happens to the waste in the hammer mill?
    The waste is shredded into smaller pieces
  • organic matter (organická hmota)
    Natural waste such as food scraps
  • Which connector is used for cause and effect, not sequence?
    As a result
  • rotating drum (rotační buben)
    A spinning cylinder that removes fine organic matter
  • wetted mixture (navlhčená směs)
    Waste that has been sprayed with water
  • residue (zbytkový odpad)
    Leftover material that cannot be recycled
  • Which connector should we use at the start of the process?
    First
  • What is one benefit of this recycling process?
    It reduces landfill and recycles useful materials
  • air classifier (vzduchový třídič)
    A machine that separates heavy and light materials using air
  • Which stage removes organic matter?
    The rotating drum
  • hammer mill (kladivový mlýn/drtič)
    A machine that shreds waste into small pieces
  • ferrous metals (železné kovy)
    Iron and steel materials attracted by a magnet
  • _______ are removed by an electromagnet.
    Ferrous metals
  • Which connector can replace "after that" for variety?
    Then
  • Why is the waste sprayed with water?
    To give paper and plastic different densities
