Screening machine

A screening machine comprises a plurality of rotating shafts arranged in parallel, each rotating shaft is provided with a plurality of rotating discs, gaps between the rotating discs on the adjacent rotating shafts form screening gaps, and a material pouring opening and a moving mechanism for driving the material pouring opening and the rotating shafts to generate relative displacement are arranged above the rotating shafts. The rotary table has the advantages that the rotary table does not need to be replaced or replaced in a delayed mode under the condition that abrasion of sieving gaps is increased, equipment operation cost is reduced, downtime is shortened, and production efficiency is improved. 一种筛分机，包括多条平行排列的转轴，每条转轴设有多个转盘，相邻转轴上的转盘之间的间隙构成过筛间隙，在转轴上方设有物料倾泻口以及驱动物料倾泻口与转轴发生相对位移的移动机构。本实用新型的优点是可以在过筛间隙磨损增大的情况下无需更换或者延迟更换转盘，降低了设备运行成本，较少了停机时间，提高了生产效率。
