Stainless steel 12 mesh seasoning vibrating screen/ Direct Discharge Vibrating Sifter For Flour Mill
Vibrating screens usually rely on mechanical vibration to classify various minerals in solid state and separate solid liquids. Generally, they are composed of vibrators, screen boxes, support or suspension devices, and transmission devices. Depending on the properties of the processed materials, the structure and performance of the vibrating screen vary greatly. While increasing the vibration intensity to improve the screening efficiency, how to ensure the reliability of the vibrating screen is a major problem in the design and manufacture of the vibrating screen. Large-scale high-end vibrating screens involve many disciplines and complex production processes. They are one of the important machinery in coal, chemical, food, mining and other industries.
After the vibro screen machine is started, its power device is the eccentric blocks of different phases at the upper and lower ends of the vibrating motor. Due to the high-speed placement, a composite inertial force is generated. Under the action of the sieve, it continuously reciprocates, and then drives the screen surface to vibrate periodically, so that the materials on the screen surface move in a directional and active manner with the screen box, during which materials smaller than the screen surface aperture fall to the lower layer through the screen holes , become the under-sieve material, and the material larger than the aperture of the screen surface is discharged from the discharge port after continuous jumping motion, and finally the screening work is completed. The motion trajectory of the vibrating body of the rotary vibrating screen is a complex three-dimensional curve in space. The projection of this curve on the horizontal plane is a circle, and the projection on the two vertical planes is two identical ellipses. In practical application, by adjusting the relative phase of the eccentric blocks at the upper and lower ends of the vibration motor, the movement trajectory of the material on the screen surface can be changed, so as to achieve different screening operations.
