簡述振動篩分機工(gong)作(zuo)原理以及(ji)運轉軌跡(ji)
振動篩分機(ji)(ji)(ji)是(shi)利用振動電(dian)(dian)機(ji)(ji)(ji)作(zuo)為動力源(yuan)。振動電(dian)(dian)機(ji)(ji)(ji)在振動機(ji)(ji)(ji)體上不(bu)同(tong)的(de)安裝(zhuang)組合形式，可產生不(bu)同(tong)的(de)振動運轉(zhuan)軌跡，從而有效完成各種作(zuo)業。
直線型振動：直線振動篩采用雙(shuang)振(zhen)(zhen)動電(dian)(dian)機(ji)驅動，當兩臺(tai)振(zhen)(zhen)動電(dian)(dian)機(ji)做同步、反(fan)向(xiang)旋(xuan)轉時(shi)，其偏心(xin)塊所(suo)產生(sheng)的(de)激(ji)振(zhen)(zhen)力(li)在(zai)(zai)平行(xing)于電(dian)(dian)機(ji)軸線的(de)方向(xiang)相(xiang)互(hu)抵消，在(zai)(zai)垂直于電(dian)(dian)機(ji)軸的(de)方向(xiang)疊為一(yi)合(he)力(li)，因(yin)此篩機(ji)的(de)運(yun)動軌跡為一(yi)直線。其兩電(dian)(dian)機(ji)軸相(xiang)對篩面(mian)有(you)一(yi)傾角(jiao)，在(zai)(zai)激(ji)振(zhen)(zhen)力(li)和物料自重力(li)的(de)合(he)力(li)作用下(xia)，物料在(zai)(zai)篩面(mian)上被拋起跳躍式向(xiang)前作直線運(yun)動，從而(er)達到(dao)對物料進行(xing)篩選(xuan)和分(fen)級的(de)目的(de)
