圆振动筛又叫旋振筛，属于一种高精度细粉筛分机械，由于其噪音低、工作效率高、移动方面、方便更换筛网、运转轨迹方便调节深受广大用户亲睐，不同的筛网目数采用不同的网架结构，根据筛网丝径粗细选用不同的固定网架形式，这样有利于客户快捷的更换筛网，提高工作效率，以下主要介绍圆振动筛采用(yong)的U型网架(jia)结构：
U型网架又叫子母网结构，属于旋振筛非(fei)常(chang)普遍使用(yong)的(de)型(xing)号(hao)，先(xian)用(yong)压网(wang)(wang)工(gong)(gong)(gong)装把(ba)粗(cu)丝径的(de)筛网(wang)(wang)固定(ding)在(zai)U型(xing)槽内，这(zhei)层筛网(wang)(wang)称之(zhi)为目网(wang)(wang)，再(zai)将(jiang)工(gong)(gong)(gong)作(zuo)网(wang)(wang)固定(ding)平铺在(zai)目网(wang)(wang)上边，用(yong)卡箍固定(ding)四周，这(zhei)种(zhong)网(wang)(wang)架结构的(de)优(you)势就是(shi)更换工(gong)(gong)(gong)作(zuo)网(wang)(wang)比较快，工(gong)(gong)(gong)作(zuo)网(wang)(wang)下(xia)的(de)目网(wang)(wang)其骨架作(zuo)用(yong)，支撑(cheng)工(gong)(gong)(gong)作(zuo)筛网(wang)(wang)，保证筛面的(de)平整度，防止物料冲击(ji)压塌工(gong)(gong)(gong)作(zuo)网(wang)(wang)，同时又防止筛板(ban)上的(de)弹跳(tiao)球撞(zhuang)击(ji)工(gong)(gong)(gong)作(zuo)网(wang)(wang)，把(ba)工(gong)(gong)(gong)作(zuo)网(wang)(wang)撞(zhuang)破，这(zhei)种(zhong)网(wang)(wang)架结构的(de)缺(que)点就是(shi)目网(wang)(wang)与(yu)工(gong)(gong)(gong)作(zuo)网(wang)(wang)重叠(die)部(bu)分，影响筛分面积(ji)。
