[0028] The material to be screened and eluted is placed on the combined screen 7 in the elution container 9 for screening and elution, the classification elution is realized through different aperture screens, the friction between the sand and stones is increased through vibration, the mud wrapped on the sand and stones is facilitated to be separated, and the elution effect of the sand and stones is better.

[0029] Specifically, when screening the building sand aggregate, the aggregate is placed on the top of the combined screen 7, then water is injected into the inside of the washing container 9 through the water inlet 13 and the valve 15 is tightened to avoid water leakage of the drain pipe 14, then the vibration motor 3 is started and the aggregate is screened and washed by the combined screen 7 composed of multiple layers of screen sleeves, at the same time, the water injected into the washing container 9 can also wash the aggregate, finally the valve 15 is opened and the water is drained, and the clean aggregate is taken out after repeated multiple times.
