When the plurality of screen barrels 40 are slid to be superimposed on each other, the sliding force may be applied disproportionately. In other words, a relatively large external force may be applied to one side of the plurality of screen barrels 40 , and a relatively small external force may be applied to the other side. In this case, the plurality of screen cylinders 40 may slide while the first to third stage screen cylinders 41 , 42 , 43 on one side to which a relatively large external force is applied are first overlapped.
그런데, 이 때, 제1단 내지 제3단 스크린 통(41, 42, 43)이 금속 재질의 외벽(OW)으로만 형성될 경우에, 먼저 포개어지도록 슬라이드 이동된 일측의 제1단 내지 제3단 스크린 통(41, 42, 43)의 표면에 스크래치가 발생할 수 있다.However, at this time, when the first to third stage screen barrels 41 , 42 , 43 are formed of only the outer wall OW made of a metal material, the first stage to the third stage of one side that are slid so as to be superimposed first However, scratches may occur on the surface of the screen barrels (41, 42, 43).
