Illustration of How impact Crusher runs
When the materials fall down into the feed mouth of
the impact crusher, the roller will drove them to
the togged plate with a very high speed. The large
materials will become small ones. When the small ones
fall down to the roller, they will be crushed onto
the togged plate once again. They will get smaller,
and fall down at the bottom of the impact crusher.
There the big materials become small, then they get
smaller in the seconds round.
