In the grain processing industry, sieves are important equipment for cleaning, grading, and screening in the entire processing process. The output, efficiency, and life of sieves have a direct impact on subsequent grain processing.

The horizontal rotary motion sieve is a commonly used equipment in the grain processing industry. The horizontal rotary motion of the material on the perforated working surface makes the material loose and spreads out, passes through the screen hole at a certain speed, and passes through the screen hole by the weight of the material and the pressure of the material layer. To achieve the purpose of screening, the screening can be carried out according to the different lengths and particle sizes of the particles. Generally, the screening accuracy of the horizontal rotary motion equipment is higher, but the output and efficiency are lower than that of the vibration equipment. Most of the existing rotary vibrating screens are non-replaceable and the setting of multi-layer screens is unreasonable, resulting in difficulties in the replacement and maintenance of the screens; moreover, most of the existing rotary vibrating screens are fixed on the suspension frame for screening, so The hard connection has large damping, which leads to high energy consumption, unstable equipment, and the suspension frame is prone to damage after a long period of use, resulting in potential safety hazards.
