Home Appliances Shredding and Sorting Recycling Solution

1.Home Appliance Recycling Solutions

E-waste refers to discarded electrical appliances or electronic equipment, mainly including household appliances such as refrigerators, air conditioners, washing machines, televisions, and communication electronic products such as computers and mobile phones. According to a report released by the United Nations Environment Programme in 2010, China has become the world's second largest producer of e-waste, producing more than 2.3 million tons of e-waste every year, second only to the United States which produces 3 million tons.

Due to its complex metal composition, the recycling of e-waste requires advanced processes and equipment, and many of them end up with low-cost disposal methods, such as transporting the waste from developed regions to underdeveloped regions, simply treating it, dumping it directly in landfills or even burning it. Black burning smoke, unknown soil pollution, a series of environmental protection and health risks follow.

How to handle them reasonably? Generally, after the e-waste is crushed, the differences in physical properties between components are used for sorting, including disassembly, shredding, sorting and other steps. After sorting, the recycled materials such as metal, plastic and glass can be obtained respectively through follow-up disposal. This disposal method has the advantages of low cost and simple operation, is not easy to cause secondary pollution, and can scale up, etc., so it is a hot spot of development in various countries.

2.Solution Brief Introduction

This solution of shredding and sorting for home appliances integrates hardware and software and adopts a modular design. The production line covers the feeding system, crushing system, magnetic separation system, sorting system, dust collection system, etc.

Firstly, discarded home appliances are transported to the crusher and crushed into smaller size materials. To separate iron, materials are subsequently scattered by a vibrating feeder and evenly transported to the magnetic separator. Lastly, the eddy current sorter and air sorter are ready to separate plastic, copper, and aluminum.
