針對80~100目的中藥粉，由于顆粒不算太細，且透篩率良好，建議可用全不銹鋼直線篩進行篩分。直線振動篩有著篩分效率高、單次處理量大的突出特點，特別適合篩分目數要求不高、生產量需求較大的企業使用，立友全不銹鋼直線振動篩是專為諸如醫藥類衛生要求嚴苛的行業設計生產的。該設備不僅能夠實現對中藥粉的分級篩選功能，而且在重要原材料的除雜方面也有很好的表現，只需根據篩分需求的不同對中藥粉振動篩的篩網進行更換即可實現。醫藥用全不銹鋼顆粒沖劑篩直線振動篩是利用振動電機激振的(de)(de)原(yuan)理，使物(wu)料(liao)在篩(shai)(shai)面(mian)上(shang)(shang)被拋起，同(tong)時向(xiang)(xiang)(xiang)前作直線運動，以合理的(de)(de)篩(shai)(shai)網達到(dao)篩(shai)(shai)分(fen)的(de)(de)目的(de)(de)。當縱(zong)向(xiang)(xiang)(xiang)安裝在篩(shai)(shai)體上(shang)(shang)的(de)(de)兩(liang)臺振動電機相對(dui)轉動時，兩(liang)臺振動電機兩(liang)端的(de)(de)偏心塊(kuai)便產生額定激振力，其產生在橫向(xiang)(xiang)(xiang)的(de)(de)激振力相互抵消，其縱(zong)向(xiang)(xiang)(xiang)的(de)(de)激振力通(tong)(tong)過傳(chuan)振體傳(chuan)遞到(dao)整個篩(shai)(shai)面(mian)上(shang)(shang)，從而使篩(shai)(shai)面(mian)上(shang)(shang)的(de)(de)物(wu)料(liao)受其激振力而在 篩(shai)(shai)面(mian)上(shang)(shang)向(xiang)(xiang)(xiang)出(chu)(chu)料(liao)口方向(xiang)(xiang)(xiang)跳躍運動，小(xiao)于(yu)(yu)篩(shai)(shai)孔的(de)(de)物(wu)料(liao)通(tong)(tong)過篩(shai)(shai)孔落(luo)到(dao)下層，連續(xu)跳躍后(hou)經出(chu)(chu)料(liao)口流出(chu)(chu)，由于(yu)(yu)篩(shai)(shai)分(fen)過程合理，便可(ke)將物(wu)料(liao)經振動篩(shai)(shai)分(fen)級(ji)(ji)后(hou)，取得幾種不同(tong)程度 的(de)(de)物(wu)料(liao)，高效完(wan)成物(wu)料(liao)的(de)(de)分(fen)級(ji)(ji)工作。300目以下的(de)(de)中藥(yao)粉振動篩(shai)(shai)選(xuan)型(xing)
針(zhen)對300目以(yi)內的(de)中(zhong)藥粉，可以(yi)選(xuan)用圓形振(zhen)(zhen)(zhen)動(dong)(dong)篩(shai)(shai)進行(xing)篩(shai)(shai)分(fen)。圓形振(zhen)(zhen)(zhen)動(dong)(dong)篩(shai)(shai)也被稱為(wei)(wei)(wei)旋(xuan)(xuan)振(zhen)(zhen)(zhen)篩(shai)(shai)，是常(chang)見(jian)的(de)多功能型(xing)篩(shai)(shai)分(fen)設備，它雖(sui)然處理量不及直(zhi)線篩(shai)(shai)，但(dan)在篩(shai)(shai)分(fen)精度上(shang)(shang)可以(yi)精確(que)至400目，因其高精度、體積小的(de)特點廣受客戶(hu)(hu)喜歡(huan)。圓形醫藥振(zhen)(zhen)(zhen)動(dong)(dong)篩(shai)(shai)圓形中(zhong)藥粉振(zhen)(zhen)(zhen)動(dong)(dong)篩(shai)(shai)的(de)工作原(yuan)(yuan)理是由直(zhi)立(li)式(shi)電(dian)機作激振(zhen)(zhen)(zhen)源，電(dian)機上(shang)(shang)、下兩端安裝有(you)偏心(xin)重錘，將(jiang)電(dian)機的(de)旋(xuan)(xuan)轉(zhuan)運動(dong)(dong)轉(zhuan)變為(wei)(wei)(wei)水平、垂直(zhi)、傾斜的(de)三(san)(san)次(ci)元運動(dong)(dong)，再(zai)把這個運動(dong)(dong)傳遞給篩(shai)(shai)面(mian)。調節上(shang)(shang)、下兩端的(de)相位角，可以(yi)改變物料(liao)在篩(shai)(shai)面(mian)上(shang)(shang)的(de)運動(dong)(dong)軌跡(ji)，由于其振(zhen)(zhen)(zhen)動(dong)(dong)運轉(zhuan)原(yuan)(yuan)理很多企業(ye)也稱之為(wei)(wei)(wei)“三(san)(san)次(ci)元旋(xuan)(xuan)振(zhen)(zhen)(zhen)篩(shai)(shai)分(fen)過濾(lv)機”，根(gen)據外形結構被部(bu)分(fen)客戶(hu)(hu)稱呼為(wei)(wei)(wei)圓形篩(shai)(shai)，從(cong)材(cai)(cai)質上(shang)(shang)分(fen)標準型(xing)旋(xuan)(xuan)振(zhen)(zhen)(zhen)篩(shai)(shai)和普(pu)(pu)通型(xing)旋(xuan)(xuan)振(zhen)(zhen)(zhen)篩(shai)(shai)的(de)，標準型(xing)的(de)與物料(liao)接觸(chu)部(bu)分(fen)為(wei)(wei)(wei)304不銹(xiu)鋼材(cai)(cai)質，底座為(wei)(wei)(wei)碳(tan)鋼材(cai)(cai)質，普(pu)(pu)通型(xing)的(de)通體為(wei)(wei)(wei)普(pu)(pu)碳(tan)鋼材(cai)(cai)質。三(san)(san)次(ci)元旋(xuan)(xuan)振(zhen)(zhen)(zhen)篩(shai)(shai)型(xing)號是從(cong)φ400-φ1800mm直(zhi)徑(jing)，三(san)(san)次(ci)元振(zhen)(zhen)(zhen)動(dong)(dong)篩(shai)(shai)價格根(gen)據材(cai)(cai)質和直(zhi)徑(jing)大小、層(ceng)數(shu)不盡相同。300目以(yi)上(shang)(shang)的(de)中(zhong)藥粉振(zhen)(zhen)(zhen)動(dong)(dong)篩(shai)(shai)選(xuan)型(xing)
