The
raw material screening device for concrete production and
processing comprises a screening box, guide plates are obliquely fixed to the two sides of the inner wall of the screening box, a screen frame located below the guide plates is movably arranged in the screening box, a vibration
assembly driving the screen frame to move is arranged in the screening box, and a screen is fixed in the screen frame; two U-shaped frames are arranged at the top end of the screen in a sliding mode, the bottom ends of the two U-shaped frames are rotationally connected with smashing rollers, and a linkage
assembly for driving the U-shaped frames to move is arranged at the bottom end of the material guide plate. According to the scheme, when
cement falls onto a screen in a screen frame, under the movement of a vibration
assembly, the screen frame is driven to continuously vibrate up and down, the screen frame drives the screen to continuously vibrate up and down, the
cement is screened, meanwhile, under the cooperation of a linkage assembly, a U-shaped frame is driven to horizontally move, and the U-shaped frame drives a smashing roller to horizontally move, so that the
cement is smashed. And the caked cement can be crushed during movement of the crushing rollers, so that the cement can be fully screened conveniently, and the
screening effect of the cement is improved.
