WASTE SORTING PRINCIPLE

How does waste sorting machine work?

Municipal solid waste enters into the feeding system by grab or front loader, and then through pre-shredding and bag opening processing, by different screening equipment, such as trommel screens, ballistic screen, star screen and waste vibrating screen, separated waste to different size stream, and then use magnetic separation system, eddy current separation system, air separation system, optical sorting system and AI robot sorting system to get plastics, paper, metals and other recyclable materials.
The organic waste is sorted out, it can be used for anaerobic digestion and biogas power generation, and the residue can be used for composting.
After the inert waste is sorted out, it can be made into concrete aggregate, cement and building materials. The remaining non-recyclable high-calorific value waste often includes a small amount of mixed plastic film, a small amount of lightweight paper, composite fabrics, etc. After shredding, the size of this mixed waste is less than 50mm, which can be made RDF and SFR for incineration and power generation.

WASTE SORTING MACHINE WORKING PRINCIPLE

How does waste sorting machine work?

With guardance of this garbage sorting manual, you will have a brief idea about working principle about the waste sorting.

  1. Collect Municipal Solid Waste (MSW) to a garbage transfer station
  2. Manually pre-sorting large pieces of garbage in waste sorting center
  3. Separation of organic waste and inorganic waste with trommel screen
  4. Recycling ferrous metal with magnetic separator
  5. Recycling of non-ferrous metals with eddy current sorter
  6. Separating light waste from inert waste by the air sorting machine
  7. Adopt optical sorter to further sort recyclable waste such as plastic, paper, glass


Of course, other equpment will be applicated in the waste sorting plant to separate garbage. The principle and purpose of garbage sorting are to recycle, reduce and harmless

Chapter 1: How to handle the waste

1.Recyclable: It mainly includes with the waste paper, plastic, glass, metal and cloth. 2. Kitchen waste: Food waste including leftovers, bones, roots, leaves, peels, etc. The food waste are processed on-site by biotechnology to produce 0.3 tons of organic fertilizer. 3. Harmful garbage: Including waste batteries, waste fluorescent tubes, wastewater silver thermometers, expired medicines, etc., these wastes need special safety treatment. 4. Other garbage：Including hard-to-recycle waste such as bricks and tiles, ceramics, muck, toilet paper, and paper towels in addition to the above types of garbage, sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

Chapter 2: The principles of garbage handle

1. Principles of division and use. The purpose of classification is to classify waste as waste, use existing production capacity, recycle recycled products including materials and energy use, and dispose of temporarily unavailable waste. Classification is to increase the utilization of materials and reduce the amount of incineration and landfill. 2. Principles adapted to local conditions. Enterprises 'ability to recycle waste, residents' resources, living habits, economic and psychological capabilities are all the same. Convenience, applicable software and hardware facilities facilitate people and guide the public to correctly classify them. 3. Conscious autonomy. Communities and residents have gradually formulated a code of conduct for "reduction, recycling, consciousness and autonomy", innovated waste classification and treatment models, and became the main force for waste reduction, classification and recycling.

Chapter 3: Method of waste Handle

The purpose of garbage classification is to facilitate the end-of-line processing and improve the efficiency of garbage processing. In the future, garbage classification may become more and more effective and contributed. Priority should be given to ensuring the purity and accuracy of the three types of food waste, recyclables and hazardous waste, but other types of waste are inherently fault-tolerant. The treatment of other garbage is generally incineration, so as long as it is not too outrageous, even if there are some slight deviations, it will not affect the post-processing much. So if you can not finger out which kind of garbage to deal with,you may wish to put it in other garbage categories, which can help everyone reduce unnecessary tangles when sorting and placing, and also reduce the difficulty of sorting some garbage.

Chapter 4: Purpose and significance of waste sorting

The benefits of garbage sorting are obviously. The waste being sorted and sent to the processing factory instead of landfill, which will not only save the land resources, but also avoids the pollution caused by landfill or incineration. In that case the waste becomes valuable resources. In this battle between people and trash, people turned trash into friends. Therefore, waste separation and collection can reduce the quantity of waste treatment and equipment, and reduce the treatment cost, the consumption of land resources, therefor to have social, economic, and ecological benefits.

Chapter 5: How to sort waste metal from trash

1.It is inevitable for the replacement of used and new metal products application. Due to the corrosion, damage and natural elimination of metal products, a large amount of waste metal is generated every year. If these waste metals are discarded at will, it will cause environmental pollution and metal resources waste. 2. It is urgent matter to recycling and utilization of abandoned nonferrous metals. The eddy current non-ferrous metal sorting machine sorts non-ferrous metal particles with different shapes. By adjusting the rotor speed, feeding speed, and belt speed, it achieves a good separation effect. It has very good applications in the fields of industrial decomposition and industrial slag recovery. 3. The ferrous metal can be well separated from the garbage by using a magnetic separator.

Chapter 6: How to sort plastic waste

The classification of waste plastics mainly includes landfilling, incineration & pyrolysis, melting and recycling. The plastic waste should be classified first to with different processes for continued processing. The plastic waste sorting methods include manual sorting, magnetic sorting, electrostatic stacking, pneumatic sorting and photoelectric sorting. By the manual sorting method resin product can be classified by experience worker, plastic will be divided into different types of products such as tubes, films, foams, etc. or remove foreign substances in plastics such as metals, wood, paper, etc. Removal of iron and steel impurities from plastics. Electrostatic sorting is the use of plastics with different charging characteristics under electrostatic induction. Pneumatic sorting is the use of different plastics with different resistances in the air. It can also be separated by photoelectric sorting according to the material of plastic.

Chapter 7: How to sort waste paper from trash

1.The Food and Agriculture Organization of the United Nations divides waste paper into four categories according to different types, which are newsprint and book waste, cardboard box waste, high-quality waste paper and other waste paper. 2. The classification of waste paper lead a direct impact on the collection and treatment of waste paper. Different types of waste paper with different fiber types, components, and properties. Sorting waste paper can achieve the purpose of grading and making full use of the paper waste. 3. By a bounce screen with sieve holes, with the horizontal and vertical movements to sort waste paper into three output: one is 3D shaped bottles, jars and other debris. Second is shredded paper and deinking Small size (such as ≤50mm) scraps of paper, and the laste is a type of mixture of 2D sheet printing paper, wrapping paper, film, etc. 4. Then by the photoelectric sorter for further sort waste paper

Chapter 8: The status of Global Waste Sorting

Waste sorting has been carried out in developed countries around the world for a long time, such as Japan, Germany, and Sweden, and is currently in a relatively mature stage. Reviewing foreign experience in waste classification, we can summarize several point for attention. First, it is an important trend for resource utilization. From the development experience of countries with successful waste classification, we can see that these countries have largely turned waste into treasure by means of incineration to generate electricity or heat, compost, and recycling. Resource recovery utilization. Second, a good incentive and constraint mechanism. Economic incentives and legal constraints have an important impact on promoting residents' waste sorting. Third, a clear and clear garbage classification system. It is clear that the waste classification is workable, which helps residents to effectively classify domestic waste and reduce the cost of terminal treatment.

Chapter 9: Development of future for waste sorting

1. AI intelligent identification alarm for household waste. Intelligent garbage compartment, which can collect and identify the domestic garbage images. 2. Intelligent domestic waste sorting and transportation. Different types of domestic garbage trucks automatically identify and sort garbage bins, and collect and transport them to ensure that they are sorted. 3. Automatic classification of domestic waste. Build an artificial intelligence-based intelligent garbage classification system through garbage data training and testing. 4. GPS garbage collection robot. Solve the problem that if residents can't place garbage regularly. Residents can issue instructions through the APP. After receiving the order, the community robot can use its own GPS and motion sensors to locate the designated location of the resident. When it arrives at the designated place to meet the residents, the residents can put the garbage into a specific pocket of the robot, and the robot will automatically put the garbage into different trash bins.
