The application provides an aluminum metal extraction system of waste incineration slag, and relates to the field of waste incineration slag recycling. The aluminum metal extraction system of waste incineration slag comprises a first dehydration screen and a second dehydration screen. After the 32-75 mu m water-sand mixture is separated by the first dehydration screen, the remaining slag is transferred to the second dehydration screen.

The aluminum metal extraction system of waste incineration slag can divide the slag with different diameters into different eddy current separators for processing. The drying and dispersing vibration equipment can dry the slag. The water-containing slag can be dispersed by using the scraping teeth and vibration.

The particle diameter is large, and the water content is low, so the scraping teeth can be directly used to disperse the slag. After the slag is dispersed and dried, the subsequent sorting equipment can more completely pick out the aluminum slag inside.
