Specialized Crushing And Screening Equipment For Metal And Concrete
Building Materials
Product Description Of Metallurgy Machine
The comprehensive utilization project of construction waste
crushing stations can comprehensively utilize the resources of
construction waste. It not only enables the "reduction, resource
utilization and harmless treatment" of construction waste, reducing
its impact on the environment, but also adopts scientific
management and effective measures to reduce and reuse it. Over 90%
of construction waste consists of building materials such as waste
concrete, waste bricks and waste mortar. By using crushers to
classify, crush and screen construction waste, it can be turned
into treasure and rationally recycled and reused. After sorting,
rejection or crushing, it can be reused as a recyclable resource
and become the second resource in the construction industry. Metals
such as scrap steel bars, scrap iron wires, scrap electrical wires
and various scrap steel fittings, after sorting, concentrating and
remelting, can be reprocessed and manufactured into steel of
various specifications. Waste materials such as bricks, stones and
concrete, after being crushed, can be used as substitutes for sand
in masonry mortar, plastering mortar, concrete bedding, etc.
They can also be used to make building materials such as blocks,
paving bricks and lattice bricks. Making bricks from construction
waste features "three savings", "three cleanings" and "three
modernizations". It also has the characteristics of energy
conservation, water conservation, coal conservation, clean air,
clean environment and clean production. It can truly achieve the
reduction, resource utilization and harmless treatment of
construction waste. Thus, a transformation from the traditional
model of building materials → buildings → construction waste to a
comprehensive utilization model of building materials → buildings →
construction waste → recycled raw materials can be achieved.
The process of construction waste treatment and the reuse of new
materials
The construction waste stored in a centralized manner enters the
professional construction waste crusher, where it is crushed into
powder and concrete sand and gravel particles. Then, it is conveyed
to the vibrating screen through a conveyor belt for screening,
separating out the lighter wood chips. Next, the metals such as
steel bars and iron wires in the construction waste are separated,
and the steel bars, iron wires, etc. are attracted and separated
for recycling by a magnetic device. Thirdly, the particles of
different sizes and specifications produced after crushing are
conveyed to the silos respectively by the conveyor belt through
different screening devices on the vibrating screen for future use.
Construction waste goes through several steps
classification → crushing → dust removal → screening to obtain
finished sand and powder of different specifications. These raw
materials go through more than ten processing techniques such as
raw material activation, physical treatment, addition to the
formula for stirring, and reasonable gradation. The recycled and
environmentally friendly products produced have obvious advantages
in terms of compressive strength, flexural strength, and heat
insulation. More than 40 kinds of environmentally friendly building
materials can be developed from construction waste.
- The particle size of the finished product is below 12mm. These raw
materials are the best for manufacturing environmentally friendly
non-fired bricks and cut bricks. The dust collected by the dust
collector can also be used to make non-fired bricks or cut bricks.
The solid brick series has the characteristics of strong
anti-weathering ability and no radiation, and its service life is
more than 20 years longer than that of traditional fired bricks.
- The finished product is 12-30mm bone and stone materials. These
aggregates can be used as auxiliary materials for the foundation of
buildings or roads. The hardness coefficient of construction waste
is between 2 and 3. After crushing, materials with this hardness
coefficient can be fully used as building auxiliary materials.
- The finished materials can be used for making concrete mixtures,
bricks and tiles, road foundations, and other building auxiliary
materials, etc.
- The finished materials after processing construction waste can be
used to make lightweight aggregate concrete, lightweight slabs for
building partition walls, lightweight aggregate concrete small
hollow blocks, and at the same time, it can produce recycled
aggregate building panels, recycled aggregate mortar and other
recycled products.
- It can be made into various building materials and products such as
paving bricks, lattice bricks, partition wall bricks and grass
planting bricks that are widely used on municipal roads. Grass
pavers are of high strength, environmentally friendly, anti-slip
and durable, and can be used on the roads of streets, squares,
gardens, etc
Production process flow Of Metallurgy Machine
This project, through the classification, crushing and screening of
construction waste, produces aggregates that partially replace
natural sand and gravel. Some of the aggregates are used as raw
materials for deep processing by enterprises, combined with cement,
to produce ready-mixed mortar, cement admixtures, concrete products
and other products. The remaining part is sold as commercial
aggregates to concrete mixing plants, ready-mixed mortar stations,
and backfilling of road structure foundations, etc. The selected
fine powder is used for the production of concrete products, and
the yellow soil screened out at the primary stage can be used as
backfill soil or supplied to the garden department as greening
soil.
