Destoners

For cost-effective removal of stones

An integral component of Bjerke Brothers, Inc.‘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.

destonerIn 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) falls through the air stream and is 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.
