The SMICO Triple Shaft, Horizontal Screen uses three, geared drive shafts to create an oval shaped motion. This motion has proven to be ideal for applications which demand accurate sizing at high volumes. In addition to the industry standard features, SMICO has taken this design and added some unique features which offer our users even more value. One of the most notable is the inclusion of individual oil chambers. This keeps oil from being contaminated by metal shards during an oil or gear failure.
