玄武巖性狀特點

玄(xuan)武(wu)巖(yan)體(ti)積密度為2.8～3.3g/cm3，致密者壓(ya)縮強(qiang)度很(hen)大(da)，可(ke)高(gao)達300MPa，有(you)時(shi)更(geng)高(gao)，存在玻璃質及氣孔時(shi)則強(qiang)度有(you)所降(jiang)低。玄(xuan)武(wu)巖(yan)耐久性(xing)(xing)甚高(gao)，節理多，且節理面(mian)多成六邊(bian)形。且具脆性(xing)(xing)，因(yin)而不易采得大(da)塊石料，由于氣孔和杏仁構造常(chang)見，雖(sui)玄(xuan)武(wu)巖(yan)地表上(shang)分布(bu)廣泛(fan)，但可(ke)作飾面(mian)石材不多。

玄武(wu)巖的(de)主要成份是二氧(yang)(yang)化(hua)(hua)(hua)硅、三氧(yang)(yang)化(hua)(hua)(hua)二鋁、氧(yang)(yang)化(hua)(hua)(hua)鐵、氧(yang)(yang)化(hua)(hua)(hua)鈣、氧(yang)(yang)化(hua)(hua)(hua)鎂(還有少量(liang)(liang)的(de)氧(yang)(yang)化(hua)(hua)(hua)鉀、氧(yang)(yang)化(hua)(hua)(hua)鈉)，其(qi)中二氧(yang)(yang)化(hua)(hua)(hua)硅含量(liang)(liang)多，約占百分之四十(shi)五(wu)至五(wu)十(shi)左右(you)玄武(wu)巖的(de)顏色(se)(se)，常見的(de)多為黑(hei)色(se)(se)、黑(hei)褐或暗綠(lv)色(se)(se)。因其(qi)質地致密(mi)，它的(de)比重(zhong)比一般花崗巖、石灰巖、沙巖、頁巖重(zhong)。

加工工藝及優點

玄武巖顎式破碎機采用高強度錳鋼，一次(ci)成型鑄造，具有耐磨、抗壓、壽命長等優點。主要適用破碎大、中、小型石塊和相(xiang)應(ying)的物體。

玄武巖顎式破(po)碎(sui)機(ji)的(de)(de)結構主要(yao)有機(ji)架、偏心(xin)軸、大皮(pi)帶輪、飛輪、動顎、側(ce)護板(ban)(ban)、肘板(ban)(ban)、肘板(ban)(ban)后座、調隙螺桿、復位彈(dan)簧、固(gu)(gu)定(ding)顎板(ban)(ban)與(yu)活(huo)動顎板(ban)(ban)等(deng)組(zu)成(cheng)，其中肘板(ban)(ban)還(huan)起到保險(xian)作用。玄武巖顎式破(po)碎(sui)機(ji)是以電(dian)動機(ji)為動力，通(tong)過電(dian)動機(ji)皮(pi)帶輪，由三(san)角帶和槽輪驅動偏心(xin)軸，使動顎按預(yu)定(ding)軌跡作往復運動，從而將進入由固(gu)(gu)定(ding)顎板(ban)(ban)、活(huo)動顎板(ban)(ban)和邊(bian)護板(ban)(ban)組(zu)成(cheng)的(de)(de)破(po)碎(sui)腔(qiang)內的(de)(de)物(wu)料(liao)予以破(po)碎(sui)，并通(tong)過下部的(de)(de)排料(liao)口將成(cheng)品物(wu)料(liao)排出。

該系列顎(e)(e)式(shi)(shi)破(po)碎(sui)(sui)機(ji)(ji)(ji)破(po)碎(sui)(sui)方式(shi)(shi)為曲(qu)動(dong)(dong)(dong)(dong)擠壓型(xing)，電(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)驅動(dong)(dong)(dong)(dong)皮(pi)帶(dai)和(he)皮(pi)帶(dai)輪(lun)，通過(guo)偏心軸使(shi)動(dong)(dong)(dong)(dong)顎(e)(e)上下運動(dong)(dong)(dong)(dong)，當動(dong)(dong)(dong)(dong)顎(e)(e)上升時(shi)肘(zhou)板(ban)(ban)(ban)和(he)動(dong)(dong)(dong)(dong)顎(e)(e)間夾角變(bian)大，從而推動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)顎(e)(e)板(ban)(ban)(ban)向(xiang)定顎(e)(e)板(ban)(ban)(ban)接近，與此(ci)同(tong)時(shi)物(wu)料(liao)被擠壓、搓、碾等多重破(po)碎(sui)(sui);當動(dong)(dong)(dong)(dong)顎(e)(e)下行時(shi)，肘(zhou)板(ban)(ban)(ban)和(he)動(dong)(dong)(dong)(dong)顎(e)(e)間夾角變(bian)小，動(dong)(dong)(dong)(dong)顎(e)(e)板(ban)(ban)(ban)在拉桿、彈簧的作(zuo)用下離開定顎(e)(e)板(ban)(ban)(ban)，此(ci)時(shi)已破(po)碎(sui)(sui)物(wu)料(liao)從破(po)碎(sui)(sui)腔(qiang)下口排出，隨(sui)著電(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)連續轉動(dong)(dong)(dong)(dong)破(po)碎(sui)(sui)機(ji)(ji)(ji)動(dong)(dong)(dong)(dong)顎(e)(e)作(zuo)周(zhou)期性(xing)的壓碎(sui)(sui)和(he)排料(liao)，實現批量生產。
