Types of Waste Sorting Equipment

Waste sorting equipment is an important tool for efficient waste management. Through advanced technologies such as screening, magnetic separation, and air classification, it achieves efficient and precise waste sorting. These devices greatly enhance the efficiency of waste processing, reduce environmental pollution, and contribute to the construction of a green and environmentally friendly society.

Waste sorting equipment can be categorized into the following types based on different sorting principles and technologies:

1. Screening Equipment

- Working Principle: Waste is separated into large, medium, and small particles through screens of different specifications.

- Application Scenario: Mainly used for the pre-treatment of solid waste.

2. Gravity Separation Equipment

- Working Principle: Separation is achieved by exploiting the differences in specific gravity of materials, such as air flotation and jigging.

- Application Scenario: Suitable for separating materials of different densities.

3. Magnetic Separation Equipment

- Working Principle: Separation is based on the magnetic differences in materials, using permanent magnets and electromagnets.

- Application Scenario: Used for sorting mixed metals.

4. Electrostatic Separation Equipment

- Working Principle: Separation is based on the differences in electrical conductivity of materials, such as electrostatic and corona separation.

- Application Scenario: Applicable for separating materials with different electrical conductivities.

5. Optical Sorting Equipment

- Working Principle: Separation is based on the differences in optical properties of materials, such as X-ray fluorescence and infrared spectroscopy.

- Application Scenario: Suitable for precise classification of materials with different optical properties.

6. Air Current Sorting Equipment

- Working Principle: Uses the force of air currents to blow out lightweight waste such as plastic bottles and paper.

- Application Scenario: Applicable for separating lightweight materials.

7. Mechanical Arm Sorting System

- Working Principle: Employs automated mechanical arms to precisely grasp waste based on sensor recognition results.

- Application Scenario: Achieves automation and efficiency in sorting.

8. Biological Sorting Equipment

- Working Principle: Achieves separation of organic matter from other substances through microbial decomposition.

- Application Scenario: Designed for organic waste, such as composting facilities and anaerobic digestion tanks.

9. Eddy Current Separator

- Working Principle: Suitable for separating non-ferrous metals, such as aluminum and copper, by generating eddy currents in a rapidly rotating magnetic field.

- Application Scenario: Separation of non-ferrous metal materials.

These devices each have their characteristics and application ranges, and the appropriate equipment can be selected based on the characteristics of different materials and processing requirements to achieve efficient sorting.
