Efficient fine-grained material screening device and screening method thereof

The invention belongs to the technical field of processing devices, and particularly relates to an efficient fine-grained material screening device and screening method thereof. The efficient fine-grained material screening device comprises a shell, a control panel, a variable-frequency controller, a combination plate, a fixing pile and a transverse plate, wherein the front side wall of the shellis fixedly connected with the control panel through screws. According to the efficient fine-grained material screening device and screening method thereof, aiming at the problems existing in conventional manual wet screening, mechanical vibration and ultrasonic waves participate in the screening process at the same time, a positive effect is achieved on screening of fine-grained materials, lumps are more easily removed, qualified materials are more easily screened, the stability and reproducibility of fineness data are improved, the screening time is shortened, and the operation efficiency isobviously improved; and cl
