[0002] A steel slag classification and filtration device is a device used for screening and filtering steel slag so as to classify steel slag particles of different sizes.

[0003] When using a classification and filtration vibrating screen machine to process steel slag by screening and filtering, the steel slag is poured into the feed hopper, and then enters the first layer of filter screen from the feed hopper. The classification and filtration vibrating screen machine is started to vibrate, so that the steel slag rolls and vibrates on the first layer of filter screen. The smaller steel slag will fall into the next layer, and the filtered steel slag will move towards the discharge conduit along with the vibration and the inclination of the filter screen and then be discharged. And so on, until the classification and filtration is completed. Since the traditional filter screens are installed in the inner wall of the classification and filtration vibrating screen machine from bottom to top in sequence, when the filter screen at the bottom or in the middle is blocked and needs to be cleaned or needs to be replaced, all the filter screens above it need to be disassembled to replace the filter screen at the bottom or in the middle.
