窩眼筒式精選（分級）機 Eye socket cylinder cleaning (grading) machine

物料從主機架上部入口處進(jìn)入窩眼滾筒內，旋轉的窩眼滾筒上沖有尺寸精確的氣泡式窩眼，小于窩眼內徑的顆粒會(huì )嵌入窩眼內，隨滾筒上行一定距離后落入中心U型料槽，而后被U型料槽內的螺旋攪龍排出設備；而較長(cháng)或較大的顆粒則因無(wú)法嵌入窩眼內徑而滯留在滾筒里，最終經(jīng)由滾筒內的另一端出口排出。因此，窩眼筒精選機不僅可以去雜質(zhì)，也可以當成更精準的分級機使用。

The material enters the socket drum from the upper entrance of the main frame, and the rotating socket drum is punched with a bubble socket with accurate size. The particles smaller than the inner diameter of the socket will be embedded in the socket, which will fall into the central U-shaped trough after a certain distance up the drum, and then be discharged by the spiral auger in the U-shaped trough; the longer or larger particles will stay in the roll because they cannot be embedded in the inner diameter of the socket In the cylinder, it is finally discharged through the outlet at the other end of the cylinder. Therefore, the machine can not only remove impurities, but also be used as a more accurate classifier.
