Gravity grading stone remover is a widely used oilseeds cleaning equipment. Its main function is to effectively separate stones, clods and other impurities in grain by using the gravity difference between materials and impurities, so as to improve the purity of oilseeds and ensure the smooth progress of subsequent processing. The following is a brief description of the working principle of the gravity grading stone remover.

The core principle of the gravity grading stone remover is based on the density difference between materials and impurities, and the separation is realized through the comprehensive action of vibration, airflow and screen surface. Specifically, the gravity grading stone remover usually consists of a screen surface, a vibrating device, a fan and an adjusting mechanism. After entering the equipment, the materials are first evenly distributed on the screen surface. Under the action of the vibrating device, the material forms a flowing thin layer on the screen surface.

In this process, the airflow generated by the fan blows upward from the bottom of the screen surface, forming a certain buoyancy effect. Because of the different gravity of oilseeds particles and stones, the lighter oilseeds particles will gradually move upward under the dual action of airflow and vibration, while the heavier stones will settle to the bottom of the screen surface and be discharged from the equipment along a specific trajectory.

In addition, the gravity grading stone remover is equipped with an adjusting mechanism, which can adjust the vibration amplitude, airflow intensity and the inclination angle of the screen surface according to the characteristics and impurity content of the oilseeds, so as to achieve the best separation effect. This flexibility enables the gravity grading stone remover to adapt to different types of oilseeds.

In a word, the gravity grading stone remover skillfully uses the specific gravity difference between materials and impurities, and realizes efficient and accurate separation under the synergistic effect of vibration and airflow. This equipment not only improves the quality of oil cleaning and processing, but also reduces the cost of manual impurity selection, and is an indispensable and important tool for oilseeds cleaning.
