顎(e)式(shi)破碎機(ji)主要由機(ji)架、偏心軸、大(da)皮帶輪、飛(fei)輪、側護板(ban)、肘板(ban)、肘板(ban)后座、調隙螺桿、復位彈簧(huang)、固(gu)定顎(e)板(ban)與活(huo)動(dong)顎(e)板(ban)等(deng)組成。

顎(e)(e)(e)式破(po)碎機破(po)碎方(fang)式為(wei)曲動(dong)(dong)(dong)(dong)擠壓型。工作時(shi)，電(dian)動(dong)(dong)(dong)(dong)機驅動(dong)(dong)(dong)(dong)皮(pi)帶和(he)(he)皮(pi)帶輪，通過(guo)偏心軸(zhou)使動(dong)(dong)(dong)(dong)顎(e)(e)(e)上(shang)下(xia)運動(dong)(dong)(dong)(dong)，當(dang)動(dong)(dong)(dong)(dong)顎(e)(e)(e)上(shang)升(sheng)時(shi)，肘(zhou)板(ban)(ban)和(he)(he)動(dong)(dong)(dong)(dong)顎(e)(e)(e)間夾角(jiao)變大，從而推(tui)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)顎(e)(e)(e)板(ban)(ban)向定(ding)顎(e)(e)(e)板(ban)(ban)接近，物(wu)料(liao)通過(guo)兩顎(e)(e)(e)板(ban)(ban)之間的(de)擠壓、搓、碾(nian)等實現多重破(po)碎；當(dang)動(dong)(dong)(dong)(dong)顎(e)(e)(e)下(xia)行時(shi)，肘(zhou)板(ban)(ban)和(he)(he)動(dong)(dong)(dong)(dong)顎(e)(e)(e)間夾角(jiao)變小，動(dong)(dong)(dong)(dong)顎(e)(e)(e)板(ban)(ban)在拉桿、彈簧的(de)作用(yong)下(xia)離開(kai)定(ding)顎(e)(e)(e)板(ban)(ban)，已破(po)碎物(wu)料(liao)在重力的(de)作用(yong)下(xia)，經顎(e)(e)(e)腔下(xia)部的(de)出料(liao)口(kou)自由卸出。隨著電(dian)動(dong)(dong)(dong)(dong)機的(de)連(lian)續(xu)轉動(dong)(dong)(dong)(dong)，動(dong)(dong)(dong)(dong)顎(e)(e)(e)做周期(qi)性的(de)壓碎和(he)(he)排料(liao)，實現批量生產。
