gravel sand making production is developed by absorbing German
advanced technology. Sanme provides complete equipments and
technical solution for gravel sand making production line.
Applicable material:
Gravel (pebble)
Application:
It is suitable for construction applications in cement concrete,
asphalt concrete and various stabilized soil, and also for highway
engineering applications in road, tunnel, bridge and culvert, etc.
Equipments:
Feeder, vibrating screen, cone crusher, VSI Crusher, belt conveyor, sand washer.
Brief introduction of Gravel sand making production line
The gravel resource in China is abundant, the main chemical
composition of gravel is silicon dioxide, secondly it is composed
by small amount of iron oxide and trace elements such as manganese,
copper, aluminum, magnesium and compound, it has natural stone
features of hard quality, compression, wear-resistance and
anticorrosion, it is an ideal material for building application.
Currently gravel sand making production lines are continually built
all over the country, which guarantee the supply of quality
aggregate for national construction projects.
0-40mm crushed stone (pebble) is used as raw material for gravel
production line, vertical shaft impact crusher (sand making machine) is adopted by the production line, this crusher is a new type sand making machine of Sanme, which has the features
of high crushing efficiency(offering fine crushing and coarse
grinding), simple structure, easy maintenance, low operation cost
and excellent particle size(cubic shape, low content of needle-like
particles).
Basic process of Gravel sand making production line:
Gravel resource in our country is abundant, and varies from place
to place. Wear resistance is firstly considered when selecting
equipments. The stone with big grain will be crushed with reference
to the crushing of granite and basalt; the stone with small grain
will be screened in advance to reduce the production cost;
Taking the gravel with grain less than 200mm as an example, the
material will be transported by feeder and belt conveyor from
hopper to 1# vibrating screen for pre-screening, the material with
grain larger than 40mm will be conveyed into cone crusher for
crushing, the material with grain of 5-40mm will be conveyed into
vertical shaft impact crusher for crushing, the material with grain
of 0-5mm will be washed by sand washer and will be discharged as
final product. The product after being crushed by cone crusher will
be conveyed to 2# vibrating screen, the material larger than 40mm
will be conveyed to cone crusher for crushing again, to achieve a
closed circuit, the material less than 40mm will be conveyed to
vertical shaft impact crusher for crushing, the material after
being crushed by vertical shaft impact crusher will be conveyed to
3# vibrating screen for screening, the material larger than 20mm
will be conveyed back to vertical shaft impact crusher for
crushing, to achieve a closed circuit, the material less than 20mm
will be conveyed by belt conveyor to final product pile, according
to the cleanness of the material, it is considered that 0-5mm
material may be washed by sand washer.
Feature introduction of Gravel sand making production line:
The sand making production line has the features of reasonable
configuration, high automation, low operation cost, high crushing
rate, energy saving, environmental protection, high capacity and
easy maintenance, the manufactured sand conforms to national
standard for construction sand, uniform grain, excellent particle
size, well graded.
The equipments of Gravel sand making production line are configured
in accordance with the specification and output as well as
application of the sand, we provide solution and technical support,
and design the process according to the production site of
customer, we make every effort to provide the most reasonable and
economic production line for customers.
