In construction (decoration) waste, besides bricks and concrete blocks, there are also wood chips, paper scraps, plastics, tree leaves, soil, etc. in the waste generated by construction (decoration) demolition, among which concrete blocks can be used as roadbeds; Light materials such as wooden blocks, paper scraps, and plastic bags also have their own uses. If these waste materials are not distinguished and treated uniformly, it will not only cause waste of available resources, but also affect the quality of treatment due to mutual interference between materials.

At present, in the treatment of construction (decoration) waste, the removal of light substances mainly relies on manual sorting, and small debris cannot be sorted out. Manual sorting has low efficiency, high cost, and poor effect, making it suitable for front-end sorting to remove large pieces of fabric, plastic, wooden sticks, and other debris with poor crushing effect by crushers.

The wind selection machine developed and designed by Guoxin Machinery is suitable for the middle and end stages of the production line. It removes light substances such as wood blocks, paper, and plastic from the crushed and screened construction (decoration) waste. After being processed by the wind selection machine, heavy substances such as bricks, concrete, and aggregates are separated from light floating objects such as plastic, wood, paper, soil, and leaves, greatly improving the appearance and performance of the finished product.

Advantages of construction and decoration waste sorting equipment:

1) Adapt to long-term work in the environment of the feeding and storage area

2) The transmission system adopts variable frequency motors and electrical protection devices, which have the characteristics of uniform speed regulation and automatic overload protection.

3) All adopt rolling bearing support structure, with good sealing and lubrication performance, low movement resistance, and easy maintenance.

4) Ensure the airtightness of the overlapping parts of the material trough, effectively preventing material leakage.

5) The frame body of the truss structure has light weight, good rigidity, small footprint, and is easy to adjust, disassemble, and transport.

6) Except for the feeding and discharging ends, the rest of the machine is equipped with a fully enclosed protective cover, which is conducive to dust removal and prevents environmental impact.

7) Adjustable speed.

8) A uniform fabric machine (with bag breaking function) is installed at the front discharge point.

9) The device has a pallet or tensioning device and is designed with a compact center distance.

10) Improve machining accuracy and ensure that each sprocket is coplanar.

11) Ensure that the support stiffness of the sprocket meets the requirements for use.

12) Ensure smooth meshing between the teeth and the chain, and smooth rotation of the main and driven shafts; The chain wheel is in full contact with the guide rail and rotates flexibly.

13) Ensure good fit between butterfly shaped plates and good sealing effect.

14) Emergency stop devices and on-site operation switches are installed near the conveyor.

15) The overall equipment is acid and alkali resistant and corrosion-resistant.
