Waste Sorting Equipment

With the acceleration of urbanization, the volume of urban waste has increased sharply, and traditional waste disposal methods can no longer meet the demands of modern environmental protection and resource recycling. The use of waste sorting equipment has become the key to solving this problem. These devices, through efficient sorting and processing technologies, achieve effective classification and resource utilization of urban waste.

Preliminary Crushing and Screening

Waste first enters a crusher for preliminary crushing, breaking large pieces of waste into smaller pieces for easier subsequent processing. The crushed waste is then conveyed to a drum screen or vibrating screen via a conveyor belt for preliminary separation based on the size of the materials. This process can effectively remove large inorganic and organic materials, laying the foundation for further classification.

Air Separation and Magnetic Separation

Waste that has undergone preliminary screening enters an air separator, which uses the principles of aerodynamics to separate materials of different densities by adjusting the air speed. Lightweight materials such as plastics and paper are blown away by the wind, while heavier materials remain on the screen. Subsequently, a magnetic separator will separate metals from the waste, using a strong magnetic field to extract metals from other waste.

Vibrating Screen and Tension Screen for Refined Separation

To further improve the accuracy of classification, waste enters a vibrating screen and tension screen for refined separation. The vibrating screen uses a bouncing action to make waste jump on the screen, which is particularly suitable for the sorting of lightweight and small particle materials. The tension screen, through a special movement, makes the distribution of materials on the screen more uniform, improving the screening efficiency.

Resource Recovery and Processing

Waste classified through the above steps can be recycled and reused according to different properties. For example, plastics can be recycled and regenerated, paper can be made into recycled paper, metals can be re-melted, and organic waste can be composted. This not only reduces the pressure of landfilling and incineration but also achieves the recycling of resources.

Through these advanced waste sorting equipment and technologies, urban waste can be efficiently classified and processed, making an important contribution to environmental protection and sustainable development.
