With the development of industry, with the production of more and more industrial solid waste and domestic solid waste, let's talk about the treatment of industrial solid waste.

Industrial solid waste often contains a large number of iron, stainless steel, copper, aluminum, magnesium, zinc and other metals with recycling value, the previous treatment method for these industrial wastes is directly into the solid waste incinerator incineration treatment, but if the direct rice ladle treatment will cause atmospheric pollution, with our country's attention to the environment, has not allowed direct incineration of these materials, So now the direct incineration process has been eliminated.

So how are the metals in solid waste sorted now?

Suzhou Dingjiahe Automation Equipment Co., Ltd. based on years of solid waste sorting experience, the metal sorting process and the required equipment in solid waste are sorted: the main process of solid waste sorting is to sort the broken metal mix, the metal is sorted out, and then the remaining solid waste is incinerated for power generation.

The metals in industrial solid waste are basically iron, stainless steel, aluminum and a small amount of copper and zinc, of which iron can be selected by removing iron, while copper, aluminum and zinc can be selected by eddy current separator, eddy current separator is mainly used for recycling and sorting non-ferrous metals in industrial and domestic waste.

Eddy current sorting machine sorting process:

When the electronic waste fragments containing non-magnetic conductor metals (such as copper, zinc, etc.) pass through an alternating magnetic field at a relative speed, inductive eddy currents are generated in these non-magnetic conductor gold chips. Because the material flow has a relative motion speed with the magnetic field, it has a thrust on the metal sheet and block that produce the eddy current. Using this principle, some non-ferrous metals can be separated from the mixed material flow.

The recycling of non-ferrous metals reduces the waste of metal resources and realizes the recycling of metal resources, in which the eddy current separator plays an important role.
