Xinxiang Dayong DYB series swing sieve is a circular sieving machine specially designed according to the requirements of large-scale granular material screening and high-precision screening in industrial production. It can meet customers' efficiency problems and fine process requirements for granular material screening. Simulate the artificial sieving motion. By adjusting the eccentricity, radial and cut angle, the circular motion of the screen is combined with the parabolic motion of the dust upward to create a three-dimensional rolling motion of horizontal and throwing. Spreading in the axial direction with spiral motion, so as to complete the sieving process of fine particles, which meets all fine and ultra-fine ranges of powder and particulate materials, especially suitable for difficult-to-handle materials.
