De Stoner facilitates the removal of stones and other foreign particles from input grains by separating impurities based on their densities, by adjusting the aspiration system. De stoners can be used to segregate the granular products where the particles are approximately the same size but, differ in weight.
AGI Milltec De Stoner efficiently removes small amount of heavy material from a larger quantity of light material. These are designed to have a long operational life and are installed with closed circuit dust aspiration systems and lighting systems to enable easy viewing of the components of the equipment.
Grains are evenly distributed across the mesh screen, becoming stratified and separated by differences in specific weight through screen vibrations and rising airflow. Dust and other lightweight foreign materials are then efficiently conveyed to the dust collecting unit with the airflow. The sorted grain/stone mixture that passes through the upper and lower screens drops down to the resorting deck, where heavy materials, including stones and other foreign particles, are swiftly removed by the resorting screen.
