NS Closed Circuit Destoner
For cost-effective removal of stones
An integral component of Northland Superior's in-line grain cleaning system is the NS-DS-24 CC Destoner. The destoner is typically placed in the grain
flow after the combination length and width separator. Its function is to remove stones, iron, fertilizer granules, dirt, glass, and other heavy
foreign materials from grain. The primary function of the destoner is to separate this unwanted material prior to the grain flow entering the thresher.
In operation the NS-DS-24 CC Destoner separates foreign material from the grain by gravity. Grain enters the destoner at the product inlet. The grain
is then elevated by upward air pressure generated from the fan. The heavy material (stones) fall through the air stream and are discharged from the
machine. The grain that is elevated continues upwards. The heavier grain falls into the first settling chamber and the lighter grain continues to the
second chamber to be discharged.
