Aged Waste Treatment Equipment

Aged waste refers to household garbage that has been accumulating in landfills or dumping sites for a long time. Due to prolonged natural degradation, this waste has become very complex, containing a variety of components such as organic matter, inorganic matter, metals, plastics, etc. To effectively handle aged waste, reduce its environmental impact, and achieve resource recycling, a series of professional aged waste treatment equipment has emerged. These devices can separate useful substances from aged waste and remove harmful substances through physical and chemical methods, achieving the goals of reduction, harmlessness, and resource utilization.

Main Components of Aged Waste Treatment Equipment

1. Shredder (Bag Breaker):

   - Function: Used for the preliminary shredding of large pieces of waste, especially for bags containing mixed waste. The bag breaker can effectively open the bags, releasing the waste inside for subsequent sorting and processing.

   - Features: Equipped with high-strength blades and rotating shafts, capable of dealing with various hardness levels of waste.

2. Vibrating Screen:

   - Function: Classifies waste by particle size through vibration, with larger particles remaining on the screen and smaller particles falling through the screen holes.

   - Features: The screen mesh can be replaced as needed to meet different particle size sorting requirements.

3. Bounce Screen:

   - Function: Mainly used to separate light and heavy waste, using different bouncing frequencies to separate light waste (such as plastic film) from heavy waste (such as soil, rocks).

   - Features: The screen surface is inclined, driven by a motor to produce vibration, causing waste to jump forward on the screen.

4. Tension Screen:

   - Function: Suitable for the separation of fine particles, achieving high-efficiency screening through high-frequency vibration and special screen mesh structure.

   - Features: The screen mesh has a certain elasticity, which can effectively reduce blockage.

5. Belt Conveyor:

   - Function: Responsible for transporting waste from one processing stage to the next, ensuring the continuity of the entire treatment process.

   - Features: Can be customized in length and inclination angle according to the site layout, with strong adaptability.

6. Air Separator:

   - Function: Uses air currents to separate light waste (such as paper, plastic) from heavy waste (such as metal, glass).

   - Features: By adjusting the air flow speed, the separation effect can be flexibly controlled.

7. Dry Magnetic Separator:

   - Function: Used to separate ferromagnetic substances in waste, such as nails, screws, etc.

   - Features: No need for water washing, suitable for handling dry waste, avoiding secondary pollution.

Depending on different treatment requirements and site conditions, the above equipment can be flexibly combined to form a complete aged waste treatment line. For example, a typical treatment process may include the following steps:

1. Pre-treatment stage: Use the shredder to break down large pieces of waste, then send it to the vibrating screen for preliminary grading through the belt conveyor.

2. Sorting stage: Waste graded by the vibrating screen is sent to the bounce screen and tension screen to further separate light and heavy waste.

3. Fine sorting stage: Use air separators and dry magnetic separators for fine separation of specific components, extracting valuable recyclables.

4. Final treatment: Separated organic matter can be used for composting, inorganic matter can be used as construction materials, and harmful substances need to be specially treated.

Through the collaborative work of these devices, aged waste can not only be effectively treated but also achieve the maximum utilization of resources, contributing to environmental protection and sustainable development.
