The amount of processing required True
to produce suitable aggregate
materials for construction purposes
depends on the nature of the raw
materials available and the desired
attributes of the end product.
Smaller commercial aggregate False
plants are the major source of
crushed stone for the construction
industry in metropolitan areas.
Crushing plants use step reduction False
because the amount of size
reduction accomplished is indirectly
related to the energy applied.
When the difference between the False
size of the feed material entering the
crusher and the size of the crushed
product is small, a large amount of
energy is required.
, Jaw crushers are typically employed False
as tertiary units because of their
large energy-storing flywheels and
high mechanical advantage.
Jaw crushers do not handle slabby True
material well.
The space between the jaws False
increases as the stone travels
downward under the effect of gravity
and the motion of the movable jaw,
until the stone ultimately passes
through the lower opening.
Jaw crushers are usually designed False
with the toggle as the strongest part.
Double-toggle Blake-type jaw False
crushers are so small and light that
they lend themselves to portable
applications.
Gyratory crushers are the most True
efficient of all primary-type crushers.
If a gyratory crusher is used as a False
secondary crusher, the size selected
may be dictated by the size of the
rock from the blasting operation or
by a desired capacity.
