What is the working principle of the screening machine?

     Everyone knows about the screening machine, the following is a small series for everyone to do related knowledge sharing, look together

      The screening machine is driven by a double-vibration motor and works on the principle of vibration motor excitation. When the two motors are synchronously and reversely rotated, the vibration forces generated by the eccentric blocks cancel each other in a direction parallel to the axis of the motor, and the screening machine is stacked in a direction perpendicular to the motor axis, so that the movement of the sieve machine It is a straight line. The two motor shafts of the screening machine have an inclination angle with respect to the screen surface in the vertical direction. Under the combined action of the vibration force and the material self-gravity, the material is thrown up and jumped forward on the screen surface to make a linear motion to match the screen to the screen. The purpose of the split, this is the actual working principle of the linear vibrating screen.

       The material produces the principle of specific gravity segregation under the dual action of aerodynamic force and vibration friction. By adjusting the technical parameters such as wind pressure and amplitude, the material with larger specific gravity is allowed to sink to the bottom, and the surface of the screen is moved from low to high. The small material suspended in the surface moves from high to low, thus achieving the purpose of separating the specific gravity. The machine is suitable for removing lighter impurities such as glutinous seeds, bud seeds, worms, mildew granules and black powder particles in wheat, corn, rice, sunflower seeds, watermelon seeds, various kinds of beans and other miscellaneous grains. At the same time, the upper part of the vibration table of the model is designed with a stone dip angle to separate the stones in the material.

      The sieve size of the lower sieve is smaller than the geometric size of the millet, and the full millet cannot fall, and the impurities smaller than the millet fall. At this point, the impurities in the millet were screened out. The principle of the trommel screen and the vibrating screen are basically the same, except that the vibrating screen is the vibrating body of the screen body, and the drum screen is the screen body rolling. It is not ideal to remove the impurities in the millet only by using the screening machine. Generally, after air separation, specific gravity, screening, and multiple processing, various impurities can be removed to achieve the desired clarity. This kind of machine is a machine that integrates these functions.
