This series vibration sieve is a kind of high precision sieving machines, its low noise, high efficiency, fully closed structure, apply to screening particles, powder and mucus material. My company in absorb international advanced technology designed on the basis of the advanced type, this spin vibration sieve highest screening 500 mesh, this machine is through the vibration motor excitation force up and down the movement, forcing material spiraling jump ahead, and eventually the material discharged by the discharging mouth. Spin vibration sieve can sieve any particles, powder,and mucus. The screening the most fine to 500 mesh or 0.028 mm, filtering the minimum to 5 microns. Grading screening, can screen of one to five layer sieve net, can at the same time for two to six levels of separation or filtering.
