The main equipment and functions of garbage screening equipment

Introduction: Garbage sorting equipment is a series of mechanical equipment used to classify and process various types of garbage, including belt conveyors, bucket elevators, screening equipment, magnetic separation equipment, wind separation equipment, manual sorting platforms, crushers and hydraulic balers. These equipment can efficiently and accurately classify mixed garbage such as domestic garbage, construction garbage, industrial garbage, etc. into recyclables, hazardous garbage, kitchen waste and other garbage. Garbage screening is an important part of the garbage treatment process. Through a series of equipment and processes, different components in the garbage are effectively separated to achieve resource recycling and garbage reduction and harmless treatment. The following is a detailed explanation of the main equipment for garbage screening and its functions:

A. Main equipment of garbage screening equipment

1. Conveying system

Function: As the starting point of the garbage screening production line, it is responsible for continuously and stably transporting garbage from the collection point to the processing area.

Equipment examples: conveyor belt, baffle conveyor, etc.

2. Crushing system

Function: Crushing large pieces of garbage into small particles for subsequent sorting and processing.

Equipment examples: bag breaker (tears open the bag only), crusher (crushes the garbage in the bag).

3. Screening system

Function: sort the garbage by size through screens with different apertures.

Equipment examples: drum screen (preliminary size screening), vibrating screen/pop-up screen/transmission screen (further refinement of sorting), coarse material screener (separation of large pieces of garbage and debris).

4. Optical recognition garbage sorting machine

Function: adopt high-tech optical sensors to identify the color, shape and other characteristics of garbage to achieve fast and accurate sorting.

Equipment example: optical recognition equipment.

5. Robotic arm sorting system

Function: according to the optical recognition results, automatically grab and sort the garbage to improve the sorting efficiency, especially for large or hazardous waste.

Equipment examples: robotic arm, sorting robot, etc.

6. Wind sorting system

Function: use aerodynamic principles to separate light materials (such as plastics and paper) from heavy materials.

Equipment example: wind separator.

7. Magnetic separation system

Function: Through the action of magnetic force, metal substances (such as iron, aluminum, etc.) in garbage are separated, which is helpful for resource recovery and reducing metal pollution to the environment.

Equipment examples: magnetic separator, iron remover, etc.

8. Chain plate feeder

Function: Ensure that garbage enters the production line evenly and stably, and prepare for subsequent screening operations.

9. Manual sorting platform

Function: For some garbage that is difficult to sort mechanically, such as batteries, fluorescent tubes and other hazardous garbage, manual sorting can be carried out through the manual sorting platform.

B. The role of garbage screening equipment:

Garbage screening equipment and processes play a vital role in the garbage treatment process. They not only improve the efficiency and quality of garbage treatment, but also promote the recycling of resources and the sustainable development of the environment.

1. Resource recovery: Through screening equipment, recyclable materials such as metals, plastics, paper, etc. in garbage can be separated for reuse to reduce resource waste.

2. Improve processing efficiency: Screening equipment can quickly and accurately classify garbage, greatly improving the efficiency of garbage treatment and reducing labor costs.

3. Reduce pollution: Through screening, harmful substances such as batteries and medicines in garbage can be separated to reduce pollution to the environment.

4. Promote sustainable development: Resource recycling and waste reduction are important means to achieve sustainable development, and screening equipment is an important tool to achieve this goal.

PS: The application of garbage screening equipment not only improves the accuracy and efficiency of garbage classification, but also contributes to the recycling of resources and the sustainable development of the environment. It is an indispensable tool for modern urban garbage disposal and resource recycling.
