Specific Gravity Separator 5CR-5 can do capacity1-3T/H , can remove impurity, broken beans and dust from green coffee bean, it adopts a positive pressure method, utilizing the combined effect of airflow and vibration friction on the materials. The higher-density materials sink to the bottom layer and move upward along the screen surface, while the lower-density materials float on the surface and flow downward, achieving density-based separation. It can be used for sorting various granular dry materials, removing grass stems, hemp ropes, dust, as well as immature, insect-damaged, moldy, and broken particles.
