The working principle of vibrating screen

  Shaker work, two vibration motors synchronized reverse rotation of the exciter excitation force generated reverse , forcing mesh sieve to make longitudinal movement of the

drive to make the material
Subject to periodic excitation force and Vibration feeder thrown forward a range, thus completing the materials screening operations . Suitable for screening sand and gravel quarry , but also

for coal preparation, mineral processing , building materials, electricity and chemical
Industry for product classification purposes . Shaker working part fixed and depend on the material slide along the face leaving materials are sieved . Fixed grizzly is more of

a concentrator applications
Generally used for rough broken or banana screen crushed before the pre-screening process . It is simple in structure , easy to manufacture . Not consume power , you can unload the ore

directly to the screen surface . The main disadvantage is the low productivity , screen
Of low efficiency, generally only 50-60%.
