Go to Shisi for an interview. Go to Shiji’s main work organization. When the material enters the de-stone screen surface, due to the difference in the levitation speed of side-by-side stones and wheat, under the combined action of appropriate vibration and updraft, the wheat with the lower suspension speed will float on the upper layer, and the side-by-side stones with higher suspension speed will sink The bottom layer is close to the screen surface, forming an automatic classification phenomenon. At the same time, due to the effect of airflow, the voids between the materials increase, and the positive pressure and friction between the material layers decrease. In a fluidized state, this further promotes the formation of automatic classification. The upper material with a lower suspension speed is driven by gravity, inertial force, air flow and continuous feeding, and the lower material is the sliding surface. Compared with the de-stone screen surface, it slides down to the wheat outlet for removal. When the upper material falls, it is suspended The high-speed side-by-side stones and other debris are gradually separated from the material layer and enter the lower layer. The lower stones and unsuspended wheat slide along the screen surface under the action of vibration, and the wheat continues to enter the upper layer in a semi-suspended state. When reaching the upper end of the stone removal screen, the lower material contains very little wheat. The wheat is blown back into the wheat stream under the action of the counter-air flow, and the side-by-side stones continue to climb up and discharged from the stone outlet.
