滾(gun)筒篩(shai)是分選(xuan)(xuan)技術(shu)中應用非常廣(guang)泛的(de)(de)一(yi)種機械，是通過(guo)對顆(ke)粒粒徑(jing)大小來控制垃(la)圾分選(xuan)(xuan)的(de)(de)，分選(xuan)(xuan)精度高(gao)。滾(gun)筒篩(shai)的(de)(de)筒體(ti)一(yi)般分幾段，可(ke)視具體(ti)情(qing)況而定，篩(shai)孔由小到大排列，每一(yi)段上的(de)(de)篩(shai)孔孔徑(jing)相同。

滾筒(tong)篩(shai)主要有電機、減速機、滾筒(tong)裝置、機架、密封蓋、進出料口組成。

滾(gun)(gun)(gun)筒(tong)(tong)(tong)裝(zhuang)(zhuang)置(zhi)傾斜安裝(zhuang)(zhuang)于機(ji)架(jia)上(shang)。電動(dong)機(ji)經減(jian)速機(ji)與滾(gun)(gun)(gun)筒(tong)(tong)(tong)裝(zhuang)(zhuang)置(zhi)通過聯(lian)軸器連接在一起(qi)，驅動(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)裝(zhuang)(zhuang)置(zhi)繞其軸線轉(zhuan)動(dong)。當(dang)物(wu)料進入滾(gun)(gun)(gun)筒(tong)(tong)(tong)裝(zhuang)(zhuang)置(zhi)后，由(you)于滾(gun)(gun)(gun)筒(tong)(tong)(tong)裝(zhuang)(zhuang)置(zhi)的(de)(de)(de)傾斜與轉(zhuan)動(dong)，使(shi)篩(shai)(shai)面上(shang)的(de)(de)(de)物(wu)料翻轉(zhuan)與滾(gun)(gun)(gun)動(dong)，使(shi)合格(ge)物(wu)料（篩(shai)(shai)下產品）經滾(gun)(gun)(gun)筒(tong)(tong)(tong)后端(duan)底部的(de)(de)(de)出(chu)料口排出(chu)，不合格(ge)的(de)(de)(de)物(wu)料（篩(shai)(shai)上(shang)產品）經滾(gun)(gun)(gun)筒(tong)(tong)(tong)尾部的(de)(de)(de)排料口排出(chu)。由(you)于物(wu)料在滾(gun)(gun)(gun)筒(tong)(tong)(tong)內的(de)(de)(de)翻轉(zhuan)、滾(gun)(gun)(gun)動(dong)，使(shi)卡在篩(shai)(shai)孔中的(de)(de)(de)物(wu)料可被彈出(chu)，防止篩(shai)(shai)孔堵塞。滾(gun)(gun)(gun)筒(tong)(tong)(tong)篩(shai)(shai)砂(sha)機(ji)、滾(gun)(gun)(gun)筒(tong)(tong)(tong)篩(shai)(shai)分機(ji)與滾(gun)(gun)(gun)筒(tong)(tong)(tong)篩(shai)(shai)的(de)(de)(de)原理(li)構造(zao)幾乎相(xiang)同，是(shi)人們(men)對它(ta)的(de)(de)(de)認識和叫法上(shang)存在差(cha)異。
