Stale garbage refers to the product of natural evolution after a long period of time after landfill. After years of microbial decomposition and fermentation, it usually has a large amount of water and a very low organic content. Basically, what is left is dust and non-degradable substances. The purpose of screening again is to screen out the non-degradable ones, mainly plastic bags, so that the pollution of these substances to the environment can be minimized.

1. Ideas for stale garbage treatment

After digging out the stale garbage, it is screened and classified according to the material utilization category. After classification, combustibles can be used for incineration power generation, humus soil can be used to cultivate urban landscape vegetation, and unusable materials are finally landfilled. After treatment, the storage capacity of the landfill can be restored to more than 70%.

2. Complete set of stale garbage treatment equipment

1. Uniform feeder, specially designed installation angle, can automatically realize uniform feeding according to production requirements without any auxiliary measures;

2. Large garbage sorting machine can classify garbage into three categories, namely large garbage, disposable garbage, humus soil, etc. , large garbage enters large garbage crusher; garbage can be processed to bag breaking machine; humus soil conveyor;

3. Bag breaking crusher: tear open all bags in the garbage, and tear large organic pieces into pieces less than 60MM. The three-section hammer knife can be bent when it encounters hardness, so that the inorganic material crushing rate is minimized. Special anti-entanglement device makes the hammer knife never entangled;

4. Comprehensive sorting machine, the disposable garbage after the bag breaking crusher meets the flat airflow vertically during the falling process. According to the principle of specific gravity and falling point, the garbage can be divided into 1: humus soil 2: combustibles and inorganics (mixed)

5. Separate combustible substances from inorganic substances, separate mixed combustible substances from inorganic substances, landfill the separated combustible substances harmlessly, and package the combustibles;

6. The separated combustibles can be used for garbage incineration plants, and humus soil can be used for landscaping soil

7. Magnetic separator: select metals for recycling;

8. Non-ferrous metal sorting machine: sort copper, aluminum, stainless steel, etc. from garbage

9. The selected high calorific value combustibles can be directly sent to the waste incineration plant for recycling after automatic packaging. The fully automatic packaging system can realize unmanned operation of compressed packages. The length of the packaging block can be set freely and the packaging value can be accurately recorded. Unique automatic packaging device, fast speed, simple structure, stable action, low failure rate, easy to clean and maintain.

10. The transportation equipment includes three types of equipment: uniform feeder, belt conveyor and chain plate conveyor. Mainly used for garbage feeding and transportation during sorting process.
