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. If it is to be dug out and incinerated, it needs to be screened, and some of the combustibles separated are used for garbage incineration, and the rest are composted, landfilled, and leachate treated according to the specific situation. Although the speed of re-sorting and incinerating stale garbage is fast, the treatment effect does not achieve the maximum treatment of garbage resources. Stale garbage is seriously harmful to the health of the surrounding people and sorting workers. After being pulled to the incineration plant, it also has a certain impact on the health of the workers in the incineration plant.

Stale garbage sorting equipment can reduce the harm of harmful substances generated by garbage to the human body. It includes stale garbage sorting machines, crushers, garbage conveyors and other process processing equipment, a complete set of processing lines. Stale garbage mainly includes plastic products, scrap iron and other hard-to-corrode garbage. After screening and processing by various equipment, the remaining organic matter can be processed into organic ecological fertilizer through high temperature and high pressure expansion; the ferromagnetic materials screened by the magnetic separator can be sent to the recycling station for reuse; the remaining plastic garbage can be mixed with sawdust to make wood-plastic boards.

The stale garbage treatment project adopts the treatment idea of ​​"aerobic stabilization + in-situ screening + classified transportation + off-site disposal". Through sorting + screening, metals and other materials are recycled, inert materials are backfilled, and combustible materials are transported and incinerated, which has realized the resource utilization of garbage. Analysis of stale garbage and sorting and processing technology of stale garbage.

Features of the stale garbage sorting machine system

1. In view of the fact that there are many broken glass in stale garbage, the disc screen structure is improved to reduce the frequency of material jamming and shutdown;

2. In view of the short construction period of stale garbage projects, the stale processing line is designed in modules to greatly shorten the project cycle;

3. In view of the adhesion of plastic and soil in stale garbage, improvements are made in air separation and material uniformity to improve air separation efficiency;

4. In view of the fact that there are many construction wastes and large pieces of garbage in stale garbage, large-piece automatic sorting equipment is used to reduce labor costs;

5. In view of the high moisture content of stale garbage, a special structure is designed and multi-stage sorting is adopted to reduce equipment failures and improve sorting effects.
