Supply Construction Waste Recycling and Processing Equipment

1. Brief introduction for Construction Waste Recycling and Processing Equipment 

Advocating energy conservation, pollution emissions reduction, volume reduction and resource recycling, and building a green construction recycling park to accomplish its core concept, NFLG recycles construction wastes and comprehensively disposes resources. The high-quality aggregate recycled by NFLG can be used for concrete, dry mortar, wall materials, and various bricks, blocks and other construction materials. At the same time, plastic pipes, cables, and iron metals are recycled and reused. Wood is processed into renewable wood, while the light-weight fuel materials are reproduced into derivative fuels to turn construction wastes into treasure at a low processing cost, obtain high returns, and achieve the sustainable development in the construction industry, thereby creating great economic values and social benefits. Construction waste recycling and processing equipment developed by NFLG integrates raw materials pre-processing, magnetic separation, sediment detachment and screening, manual sorting, light-weight material separation, and finished product stock bin discharging as a whole. The raw materials mainly refer to construction wastes, and the main finished products are recycled powders, recycled fine aggregates, and recycled coarse aggregates etc.. Using recycled aggregates to produce recycled concrete, mortar, and water stabilization crushed stone can effectively and reasonably reproduce construction wastes into a variety of construction materials. According to the different configurations of the equipment, the construction waste utilization rate can reach 90%-100%, thereby recycling the wastes and obtaining multiple benefits from cost reduction and profits increasing.

2.Characteristics for  Construction Waste Recycling and Processing Equipment 

1. Sorting

1. Construction waste presorting: preliminarily presort the raw materials of construction wastes to select and sort other wastes and large material blocks.
2. Automatic magnetic separation: remove the residual iron metal from concrete blocks and construction waste mixed materials.
3. The manual collecting platform consists of the collecting belt, collecting room, and collecting box. It adopts multi-position design to collect a few wood blocks, aluminum alloys, cables and other impurities.
4. Light-weight material separation is divided into negative-pressure adsorbent separation and positive-pressure blowing separation to realize the optimum separation of light-weight materials.
Negative Pressure:
The negative pressure absorption principle is used to achieve high separating efficiency and good environmental protection effects.
Dry separation produces no dust second pollution.
Intelligent control is used to select appropriate suction for different material features, thereby achieving the best separation.
Automatic cleaning devices are used automatically clean the adhesive materials.
Positive pressure:
Positive pressure blowing separation accomplishes accurate separation.
Positive pressure devices are used to adjust the wind volume and speed and separate heavy-weight materials.
The negative pressure drum, positive pressure blowing flow and negative pressure adsorption flow are used as negative pressure to separate medium- heavy and light-weight materials.
Full sealing and filter dust removal design is used to effectively prevent dust and noise emissions.

2.Crushing

Jaw crushers with high productivity can infinitely adjust the hydraulic pressure for discharge opening and prevent dust through grease labyrinth seals.
Impact crushers require large materials for feeding at high crushing strength, with the hydraulic device easier to maintain.
Flip-flow screening equipment strips and screens soil and mud to ensure the cleanliness.
The tri-axial elliptical horizontal screen has the advantages of both the circular vibrating screen and linear screen.
Dry shaping and sand manufacturing equipment
Dry sand manufacturing equipment

3.Storage

The centralized storage system can perform centralized aggregate storage, enclosed transmission, and unified intelligent management of automatic distributing.

Aggregate adopts unified management to automatically and uninterruptedly monitor the continuous storage operations in real time, thereby improving operating efficiency and saving energy for environmental friendly storage with no dust.

4.Mixing

Cement concrete mixing equipment: recycled aggregate →recycled concrete
Dry mortar mixing equipment: recycled fine aggregate→ recycled mortar
Asphalt mixing equipment: waste asphalt→ hot recycled asphalt mixture
Brick equipment: construction sludge, stone powder, etc. → recycled burning-free brick

5.Constrution waste derivative processing

Recycling of plastic materials, cables and tires, etc.
Recycling of iron metal and other materials, etc.
Processing of light-weight materials in the derivative fuel processing plant
Processing of waste wood in the waste wood recycling plant

6. Dust collecting system

The high-efficiency bag dust collector provides the offline ash removal dust collection function to achieve a dust collection efficiency of 99%.
Polyester peritoneal filter bags provide excellent filtering performance, with the carbon concentration less than or equal to 20 mg/m³ (under rated conditions).
Automatic differential pressure signal feedback brings high-performance automatic pulse control.

7.Business operational mode

Construction waste source: The construction waste generating units need to make clear the productivity and planning whereabouts of construction wastes to obtain the processing certification from the construction waste recycling site, thereby effectively controlling the whereabouts of construction wastes.

Construction waste collection: exercise strict supervision over collection units or individuals.

Construction waste recycling and processing site: regularly report the collection, processing and recycling of construction wastes and regularly accept the government's feasibility assessment of the equipment. 
Reuse of construction waste recycled products: regulate the acceptance criteria of recycled products and introduce relevant promotion policies.
