Liquid flows through the holes under wave crest , gas flows through the holes under trough and neither liquid nor gas flows through the holes under the wave middle that means the holes are blocked 波峰对应的筛孔通液，波谷对应的筛孔通气，波腰对应的筛孔处于阻塞状态。
The optimized sieve parameters reduce the vertical amplitude of the sieve back - end , making the grains go easily through the sieve pores to be separated , and consequently help to reduce the grain loss rate and impurity rate 优化后得到了较优的振动筛参数，有利于减小振动筛后端的垂直振幅，使得谷粒更容易穿过筛孔完成分离，有利于减小损失率和含杂率。
This machine adopts one pair of rotating grinding blade to grind form damp material into column - shape granule by stainless steel sieve cylinder which is provided for pelletize in next process 本机是通过一组旋转碾刀，将前道工序制成的湿材注入环碾刀的不锈钢筛筒筛孔中，从而制成圆柱状的湿颗粒，供下道工序抛丸使用。本设备可通过更换不锈钢筛筒来取得不同大小的颗粒。
