- Crushed stone is any
type of natural rock that, in order to be mined, has to be first blasted
from its natural state in the ground, and then processed (crushed and
screened). The most common types of stone processed into crushed stone
include limestone and dolomite, granite. Smaller amounts of marble,
slate, sandstone, quartzite, and volcanic cinder are also
used.
- Crushed stone is
produced in almost every state in the U.S. The type of crushed stone
mined from any particular state depends on the general geology and rocks
of the state. For instance, crushed limestone and dolomite is typical
Indiana, Illinois and Ohio, marble and granite from Vermont, etc.
- Even though it is
quarried and processed all over the United States, a small number of
states account for more than half of the total crushed stone production.
- Crushed stone makes
up 85 percent of aggregate production; construction sand and gravel,
about 15 percent. North Carolina is the eighth largest crushed stone
producing state in the U.S.
- Aggregate is
produced from about 135 crushed stone quarries and about 500 sand and
gravel sites throughout the state. Crushed stone, sand and gravel plants
account for 85 percent of all permitted mining operations.
- The average
production life of a crushed stone quarry is 40 to 50 years or more.
Sand and gravel deposits are typically worked out in much shorter time.
Crushed stone Production operation is used to make concrete and asphalt
roads, concrete for homes and office buildings, and is used in a wide
variety of erosion control projects. Aggregate operations are relatively
long lived and are vital to the economic health of
communities.
- Major rock types
processed by the crushed stone industry include limestone, granite,
dolomite, traprock, sandstone, quartz, and quartzite. Minor types
include calcareous marl, marble, shell, and slate. Rock and crushed
stone products generally are loosened by drilling and blasting and
then
are loaded by power shovel or front-end loader into large haul
trucks that transport the material to the processing
operations.
- The crushed stone
sand products can be used in conjunction with concrete aggregates or by
themselves to achieve desired finishes on precast concrete products as
well as many other applications where natural stone color is required.
- Decorative crushed
stone chips are available in many different colors and sizes to use as
ground cover around homes, offices, etc, in flower beds and around
shrubs.
- Tremendous
technological advances in stone crushing have taken place in the post-
second world war period to build back the war-torn countries.
- Modern mechanized
construction and the need for high strength concrete and asphalt mixes
have bought in new quality standards for aggregates with severe
conditions.
- Crushed stone is a
high-volume, low-value commodity. The industry is highly competitive and
is characterized by thousands of operations serving local or regional
markets. Production costs are determined mainly by the cost of labor,
equipment, energy, and water, in addition to the costs of compliance
with environmental and safety regulations.
