　　振動篩廠家講解礦用振動篩如何(he)選型：

　　一、考(kao)慮礦用振動篩的結構

　　從結(jie)構上(shang)來(lai)講，振(zhen)動篩(shai)一般(ban)有輕(qing)型(xing)和重(zhong)型(xing)之分。輕(qing)型(xing)振(zhen)動篩(shai)是我們生活中較(jiao)為(wei)常(chang)見的設(she)備，它(ta)體(ti)積較(jiao)小(xiao)(xiao)，主要處(chu)理(li)(li)(li)食品、化工原(yuan)料(liao)(liao)(liao)、涂料(liao)(liao)(liao)等，通常(chang)每小(xiao)(xiao)時(shi)(shi)的處(chu)理(li)(li)(li)量都在(zai)10噸(dun)以下;而重(zhong)型(xing)振(zhen)動篩(shai)通常(chang)是處(chu)理(li)(li)(li)量較(jiao)大(da)(da)的，每小(xiao)(xiao)時(shi)(shi)的處(chu)理(li)(li)(li)量上(shang)百噸(dun)或者更(geng)(geng)(geng)多，可處(chu)理(li)(li)(li)如(ru)煤炭、石料(liao)(liao)(liao)、金屬(shu)礦(kuang)等重(zhong)型(xing)物料(liao)(liao)(liao)。也(ye)就是說(shuo)在(zai)選礦(kuang)行(xing)業我們使用重(zhong)型(xing)振(zhen)動篩(shai)，不僅因為(wei)其機(ji)械自(zi)身的重(zhong)量較(jiao)大(da)(da)，也(ye)更(geng)(geng)(geng)加結(jie)實耐用，且(qie)所(suo)處(chu)理(li)(li)(li)物料(liao)(liao)(liao)的堆(dui)密度也(ye)更(geng)(geng)(geng)高。重(zhong)型(xing)振(zhen)動篩(shai)一般(ban)采用環槽鉚釘(ding)冷(leng)鉚聯接框架式結(jie)構，大(da)(da)游隙(xi)軸(zhou)承烯油潤滑的振(zhen)動器，篩(shai)網(wang)大(da)(da)都采用不銹鋼(gang)材質，尤其是采用金屬(shu)合(he)金絲(si)編制的篩(shai)網(wang)，不僅彈(dan)性好，而且(qie)更(geng)(geng)(geng)加耐磨耐腐(fu)蝕，在(zai)處(chu)理(li)(li)(li)鐵礦(kuang)石、錳礦(kuang)石等物料(liao)(liao)(liao)時(shi)(shi)使用壽命更(geng)(geng)(geng)長。

　　二(er)、考慮(lv)礦用振(zhen)動篩的性能

　　從振(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)的性能也就是(shi)篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)效率上(shang)來講，由于礦石物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)比重較(jiao)大(da)，屬(shu)于難篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)，同時(shi)因為(wei)選(xuan)礦生產線(xian)(xian)一般在(zai)(zai)露天(tian)環境下(xia)作業，所以振(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)設備好具備干、濕兩用的功能，所以物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)上(shang)的運(yun)行(xing)(xing)軌(gui)跡成為(wei)影響振(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)效率的要點。經過實(shi)踐(jian)研究(jiu)對比，圓形(xing)軌(gui)跡的振(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)篩(shai)(shai)(shai)(shai)(shai)(shai)網振(zhen)(zhen)動(dong)(dong)(dong)更加(jia)劇(ju)烈，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)上(shang)不(bu)斷翻(fan)轉、松散、跳躍(yue)(yue)著(zhu)向前運(yun)行(xing)(xing)，小顆(ke)粒物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)的透篩(shai)(shai)(shai)(shai)(shai)(shai)率更高，卡在(zai)(zai)篩(shai)(shai)(shai)(shai)(shai)(shai)孔中的物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)也可跳躍(yue)(yue)出來，防止篩(shai)(shai)(shai)(shai)(shai)(shai)孔堵塞;直線(xian)(xian)振(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)其物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)篩(shai)(shai)(shai)(shai)(shai)(shai)網上(shang)沿直線(xian)(xian)跳躍(yue)(yue)著(zhu)往復運(yun)動(dong)(dong)(dong)，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)在(zai)(zai)向前運(yun)行(xing)(xing)中有(you)著(zhu)壓實(shi)的作用，所以圓振(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)主要是(shi)對大(da)顆(ke)粒物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)進行(xing)(xing)篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)、篩(shai)(shai)(shai)(shai)(shai)(shai)選(xuan),而直線(xian)(xian)振(zhen)(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)是(shi)針(zhen)對較(jiao)細物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)進行(xing)(xing)篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)、篩(shai)(shai)(shai)(shai)(shai)(shai)選(xuan),選(xuan)型時(shi)應注意區(qu)別。

　　三、考慮礦用振(zhen)動篩的型號

　　好(hao)振(zhen)動(dong)(dong)篩(shai)的(de)結構(gou)和振(zhen)動(dong)(dong)篩(shai)的(de)類型(xing)后，我們還需要根據選礦(kuang)生產(chan)線的(de)情況來選礦(kuang)振(zhen)動(dong)(dong)篩(shai)的(de)具體(ti)型(xing)號。

　　1、篩(shai)網孔(kong)徑大小、篩(shai)孔(kong)形狀等(deng)。其依據是所(suo)篩(shai)分物料(liao)的大小和形狀以及振(zhen)動(dong)篩(shai)設備的用(yong)途，也(ye)就是說它(ta)適用(yong)于選礦生產線預(yu)先篩(shai)分、檢(jian)查或分級(ji)篩(shai)分環(huan)節(jie)。

　　2、篩網層數(shu)。也就(jiu)是說我們需要出(chu)幾(ji)種(zhong)料(liao)，例如兩(liang)層振動篩可(ke)以出(chu)三(san)種(zhong)料(liao)，一層用(yong)于篩出(chu)石粉(fen)，一層用(yong)于送至磨粉(fen)機，一層可(ke)回料(liao)至破碎設備。

　　3、生(sheng)(sheng)產(chan)(chan)能(neng)力。選(xuan)礦振(zhen)動(dong)(dong)篩(shai)的生(sheng)(sheng)產(chan)(chan)能(neng)力要(yao)與(yu)整(zheng)套生(sheng)(sheng)產(chan)(chan)線(xian)相(xiang)匹(pi)配。在生(sheng)(sheng)產(chan)(chan)線(xian)中(zhong)振(zhen)動(dong)(dong)篩(shai)只是生(sheng)(sheng)產(chan)(chan)線(xian)中(zhong)的一個環節，因(yin)此要(yao)求礦用(yong)振(zhen)動(dong)(dong)篩(shai)的生(sheng)(sheng)產(chan)(chan)能(neng)力不(bu)應(ying)小于整(zheng)個系(xi)統的設(she)計能(neng)力，如果(guo)礦用(yong)振(zhen)動(dong)(dong)篩(shai)選(xuan)型過小將限制系(xi)統能(neng)力的發揮，但也不(bu)應(ying)過大，會增加(jia)成本及運(yun)行成本各方(fang)面的投入。
