The function and working principle of domestic waste shredder

Preface: Domestic waste shredder plays an important role in the field of waste treatment. Its main functions and working principles are as follows:

A. The role of domestic waste shredder

The domestic waste shredder is mainly used to break large domestic waste into the required size for subsequent transportation, incineration, fertilizer making, granulation and other process treatments. Specifically, its functions include:

Domestic waste shredder

1. Improve incineration efficiency: The particle size of the domestic waste after crushing is uniform and easy to incinerate, thereby improving the treatment efficiency and heat recovery rate of the incinerator.

2. Convenient for transportation and storage: After the domestic waste is processed by the shredder, the volume is greatly reduced, which is convenient for transportation and storage, and reduces logistics costs.

3. Promote resource recovery: The recyclable materials in the domestic waste after crushing are easier to separate and recycle, which improves the utilization rate of resources.

4. Reduce environmental pollution: Through crushing treatment, the land area occupied by landfill can be reduced, and the pollution of garbage to the environment can be reduced.

B. The working principle of the domestic waste shredder

The working principle of the domestic waste shredder is mainly based on the mechanical principles of shearing, tearing and crushing. Specifically, its working process is as follows:

1. Material entry: The domestic waste to be processed enters the equipment through the inlet of the shredder. Depending on the type and size of the processed material, the size and shape of the inlet of the shredder may vary.

2. Cutting and tearing: The shredder usually contains one or more sets of rotating cutting blades or gears. These blades or gears cooperate with each other to apply shearing and tearing forces to the incoming materials. The shape, size and material of the blades are optimized according to the characteristics of the processed materials. As the blades rotate, the materials are gradually broken into smaller fragments.

3. Crushing and compression: During the cutting and tearing process, the materials are further broken into smaller fragments. These fragments may be further compressed and crushed to achieve the desired particle size and density.

4. Fragment discharge: The processed fragments are discharged through the outlet of the shredder. Depending on the type and purpose of the processed material, the fragments may be collected in a container or directly transported to other equipment for further processing.

PS: Domestic waste shredders have broad application prospects and important environmental protection significance in the field of garbage disposal. By understanding its working principle and function, we can better utilize this equipment to process domestic waste, promote resource recycling and sustainable development of the environment.
