Rotary Cleaning Sieve

The sieve runs with three tracks at the same time, and the right and left swaying near the inlet makes for the material to be divided evenly, the to-and-fro move of the middle sieve and the outlet makes for the classification.
  The airtight sieve with front and back dust collecting device raises little dust.
  Suspended with four steel wires, the sieve runs stably, and there is no trouble in 2 or 3 years.
