优点
在筛上物料落在筛网表面的瞬间，大颗粒被筛孔两侧立筋架起，瞬间分层，保护筛孔不受到冲击，而小颗粒物料通过筛孔筛下，提高了筛分效率，同时延长筛网使用寿命。
应用
立筋式筛网主要运用于大颗粒物料的筛分。
Advantages
At the moment when the material on the screen falls on the screen mesh surface, the large particles are put up by the vertical bars on both sides of the screen mesh holes, and the screen holes are protected from impact, while the small particles pass under the screen hole, which improves the screening efficiency and prolongs the using life of the screen mesh.
Application
Vertical bar screen mesh is mainly used for screening of large particles.
