Main description 800mm vibrating sieve soybean sifting machine uses horizontal vibration motor as its vibration source. The horizontal vibration motor has an eccentric block at both their upper and lower sides. The eccentric blocks can generate a three-dimensional movement in horizontal, vertical, and inclined directions. By adjusting the phase angles of the upper and lower eccentric blocks, the materials on the screen can be change the movement locus, achieving suitanle screening performance. Features: 1.Screening machinery is one of precised powder sieve, it is of high efficiency, screening efficiency exceeds 90%. 2. It adopts whole sealing structure design to guarantee no dust pollution, no leaking liquid, no material left in machine, and no dead angle in the net frame. 3. Small noise and light weight, easy to be installed and maintained. 4. The outlet can be adjusted at any angle, and it is easy to replace the screen. 5. The rubber ball device can reduce the material jam on the screen. 6. By adding ultrasonic device, superfine materials up to 600 mesh can be sieved.
