[0032] The implementation principle of the tailings treatment equipment of the present application is that the tailings material is firstly put into the crushing box 21 through the feed port 211, and the tailings material falls into the washing chamber 214 after being crushed by the crushing assembly. The specific crushing operation is that the driving motor drives one of the crushing rollers 22 to rotate, and the crushing roller 22 is connected to the other crushing roller 22 through the gear transmission structure, so that the two crushing rollers 22 rotate to crush the tailings material, and then the tailings material falls into the washing chamber 214 through the discharge channel 213, and then the clean water is put into the washing chamber 214 through the feed port 211 for stirring and washing. Specifically, the motor drives the horizontally arranged stirring roller 23 to stir and wash, so that the silt and tailings in the tailings are separated, and the silt sinks after being filtered by the sand screening net 24, and then the sand outlet pipe 25 is opened to discharge the silt, while the metal particles and larger mineral materials in the tailings remain on the sand screening net 24 due to the filtering effect of the sand screening net 24, and the control on the sand screening net 24 is closed. The valve is opened, water is injected into the crushing box 21 again, and then the suction device 4 is turned on to suck the metal particles and larger mineral materials into the screening device 3 for screening and then recycling. The screening principle of the screening device 3 is that the crushed mineral materials first fall on the first electromagnetic force sieve plate 32. After the first electromagnetic force sieve plate 32 is powered on, it has magnetic force, and the metal particles are adsorbed on the surface of the first electromagnetic force sieve plate 32, while other larger non-metallic solids fall into the first aggregate box 5 along the inclined first electromagnetic force sieve plate 32, and the smaller non-metallic gravel continues to fall on the second electromagnetic force sieve plate 33. The second electromagnetic force sieve plate 33 has magnetic attraction ability when powered on, and continues to magnetically attract the fallen metal particles, and the non-metallic gravel falls into the second aggregate box 6 along the inclined second electromagnetic force sieve plate 33, and replaces the empty aggregate box, disconnects the power supply of the electromagnetic force sieve plate, and continues to vibrate, and the metal particles are recovered into the aggregate box for recycling.
