振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)篩是(shi)利用振(zhen)(zhen)(zhen)(zhen)子激(ji)振(zhen)(zhen)(zhen)(zhen)所產(chan)生(sheng)(sheng)(sheng)的(de)往復旋(xuan)(xuan)型振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)而工作的(de)。振(zhen)(zhen)(zhen)(zhen)子的(de)上(shang)(shang)旋(xuan)(xuan)轉(zhuan)重(zhong)錘(chui)(chui)使(shi)(shi)篩面(mian)(mian)(mian)產(chan)生(sheng)(sheng)(sheng)平面(mian)(mian)(mian)回(hui)旋(xuan)(xuan)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong),而下旋(xuan)(xuan)轉(zhuan)重(zhong)錘(chui)(chui)則(ze)使(shi)(shi)篩面(mian)(mian)(mian)產(chan)生(sheng)(sheng)(sheng)錐面(mian)(mian)(mian)回(hui)轉(zhuan)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong),其聯合作用的(de)效果則(ze)使(shi)(shi)篩面(mian)(mian)(mian)產(chan)生(sheng)(sheng)(sheng)復旋(xuan)(xuan)型振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)。其振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)軌跡(ji)是(shi)一(yi)(yi)復雜的(de)空(kong)間(jian)(jian)曲(qu)線(xian)(xian)。該曲(qu)線(xian)(xian)在(zai)水平面(mian)(mian)(mian)投影(ying)為一(yi)(yi)圓形,而在(zai)垂直(zhi)面(mian)(mian)(mian)上(shang)(shang)的(de)投影(ying)為一(yi)(yi)橢圓形。調(diao)節(jie)上(shang)(shang)、下旋(xuan)(xuan)轉(zhuan)重(zhong)錘(chui)(chui)的(de)激(ji)振(zhen)(zhen)(zhen)(zhen)力,可(ke)以改(gai)變(bian)振(zhen)(zhen)(zhen)(zhen)幅。而調(diao)節(jie)上(shang)(shang)、下重(zhong)錘(chui)(chui)的(de)空(kong)間(jian)(jian)相位(wei)角,則(ze)可(ke)以改(gai)變(bian)篩面(mian)(mian)(mian)運(yun)(yun)動(dong)(dong)軌跡(ji)的(de)曲(qu)線(xian)(xian)形狀(zhuang)并改(gai)變(bian)篩面(mian)(mian)(mian)上(shang)(shang)物料的(de)運(yun)(yun)動(dong)(dong)軌跡(ji)。
振動篩的主要種類(lei):產(chan)品優缺點: 效率(lv)高,質量輕,系(xi)列完整(zheng)多(duo)樣,

層次多(duo),對(dui)于干物料(liao)(liao)篩分可以(yi)滿足需求。對(dui)于水分高(gao),有粘(zhan)附物料(liao)(liao),該機型(xing)(xing)不適宜,工(gong)作時振動(dong)使物料(liao)(liao)更緊(jin)實的粘(zhan)附于篩面,造(zao)成物料(liao)(liao)擁堵或者(zhe)被(bei)迫停機。由于工(gong)作原理限制(zhi),該機型(xing)(xing)耗能相(xiang)對(dui)較高(gao),尤其在大出力工(gong)況條件下。另外(wai)工(gong)作噪音(yin)和粉塵較重。
振(zhen)動篩的主要優點:
1、由于篩(shai)箱振動強烈,減少了(le)物(wu)料(liao)堵塞篩(shai)孔的現象(xiang),使篩(shai)子具有較高的篩(shai)分(fen)效(xiao)率和(he)生(sheng)產率。
2、構造(zao)簡(jian)單、拆換(huan)篩(shai)面方便。
3、篩分每噸(dun)物料所消(xiao)耗的(de)電能少(shao)。
