振(zhen)(zhen)(zhen)篩(shai)(shai)(shai)篩(shai)(shai)(shai)機(ji)主要(yao)有篩(shai)(shai)(shai)箱(xiang)、篩(shai)(shai)(shai)網、振(zhen)(zhen)(zhen)動(dong)(dong)器、減振(zhen)(zhen)(zhen)彈簧裝置(zhi)、底(di)架等組成。采用筒體式偏(pian)(pian)心(xin)軸激振(zhen)(zhen)(zhen)器及偏(pian)(pian)塊調節振(zhen)(zhen)(zhen)幅，振(zhen)(zhen)(zhen)動(dong)(dong)器安(an)裝在篩(shai)(shai)(shai)箱(xiang)側板(ban)上，并(bing)由電動(dong)(dong)機(ji)通過(guo)三角(jiao)皮帶(dai)帶(dai)動(dong)(dong)旋(xuan)轉，產生(sheng)離心(xin)慣(guan)性力(li)，迫(po)使篩(shai)(shai)(shai)箱(xiang)振(zhen)(zhen)(zhen)動(dong)(dong)。篩(shai)(shai)(shai)機(ji)側板(ban)采用優質鋼板(ban)制作而成，側板(ban)與橫梁、激振(zhen)(zhen)(zhen)器底(di)座采用高強度(du)螺栓或環槽鉚釘連(lian)接。振(zhen)(zhen)(zhen)動(dong)(dong)器安(an)裝在篩(shai)(shai)(shai)箱(xiang)側板(ban)上，一并(bing)由電動(dong)(dong)機(ji)通過(guo)聯軸器帶(dai)動(dong)(dong)旋(xuan)轉，產生(sheng)離心(xin)慣(guan)性力(li)，迫(po)使篩(shai)(shai)(shai)振(zhen)(zhen)(zhen)動(dong)(dong)。

篩機為座式(shi)安(an)裝。篩面傾角的(de)調整可通過改變彈簧支座位(wei)置高度來(lai)實現。

圓(yuan)振篩(shai)一(yi)般電動機安(an)裝在篩(shai)框(kuang)的右(you)側(ce)，也可安(an)裝在篩(shai)框(kuang)的左側(ce)，如(ru)果無特(te)殊要求，制造廠按物料運(yun)動方向的右(you)側(ce)安(an)裝供貨。

篩(shai)網是主要(yao)易損件(jian)。根據物料品種(zhong)和(he)(he)用(yong)戶要(yao)求，可采用(yong)高錳(meng)鋼編織篩(shai)網、沖孔篩(shai)板(ban)和(he)(he)橡膠篩(shai)板(ban)，篩(shai)面有(you)單層(ceng)(ceng)和(he)(he)雙層(ceng)(ceng)兩種(zhong)，各類篩(shai)板(ban)均能滿足篩(shai)分效(xiao)率高、壽命長、不堵孔的要(yao)求。
