Stone Removing machinery can remove the metal, stone and LDimpurity from the materials, also grading the materials into two grades (LD and heavy material).
The QSX-85 specific gravity grading destoner can remove the metal, stone and some LD impurities from the materials, also grading the materials into two grades (LD and heavy material).
1. The pebble selector can separate beans, seeds or grains which are same dimension (length, width, thickness and shape) but different weight according to material gravity principle.
2. They are primarily used in the elimination of heavy impurities such as stones, metallic particles ,branches, fragmentized seeds, sands and so on from raw materials. Stones can be removed automatically through specific pipeline.
