This invention discloses a raw material screening device for stone paper processing, relating to the field of stone paper processing technology. It includes multiple L-shaped plates, with fixed rings fixedly connected to the outer sides of each L-shaped plate. The L-shaped plates are also fixedly connected to the outer sides of a rotating shaft. Multiple L-shaped plates are connected by multiple fixed rings, and a fixed rod is fixedly connected to the top of each fixed ring. A roller is rotatably connected to the bottom of each fixed rod. In this raw material screening device for stone paper processing, the raw material passes through the gap between the L-shaped plates and the fixed rings, thus performing preliminary screening. Simultaneously, the rotating shaft drives the fixed rods to rotate inside the ring grooves, and the rollers, under force, drive the frame to move upwards. As the rotating shaft rotates, the frame vibrates up and down. This combined rotation and vibration causes the raw material to continuously tumble and jump inside the frame, reducing the residence time of particles in the gaps between the frames and lowering the probability of sieve clogging.
