如圖1所示，碎石機(jī)運(yùn)轉(zhuǎn)過程巾，當(dāng)主軸的中心線繞球面軸承球心0轉(zhuǎn)過一個(gè)角度口時(shí)，半徑大的下口所經(jīng)過的弧長(zhǎng)比半徑小的上口所經(jīng)過的弧長(zhǎng)要大．所以主軸與錐襯套的間隙必須是上口小、下口大，才有可能使主軸與錐襯套沿全長(zhǎng)接觸。走進(jìn)辦公樓大廳，記者看到展示在大廳的路面磚、空心墻體磚、干壘擋土墻、植草磚、透水磚、水工磚、盲道磚和彩瓦等新型環(huán)保建材后，深深地為之震撼！
含泥量增加臨界濃度將降低。隨著分級(jí)粒度的降低，臨界濃度減小，故控制分級(jí)機(jī)的給礦濃度就成為控制溢流粒度的有效手段。

鞏義黎明技術(shù)人員采用手工電弧焊，堆焊雙輥碎石機(jī)輥面，取得了使用壽命達(dá)10個(gè)月,破碎熟料15萬噸的效果。堆焊要點(diǎn)如下：（1）要選用功率為10千伏安以上的直流或20千伏安以上的交流電焊機(jī)。
錳鋼破碎板澆鑄后要通過水韌處理，水韌處理的操作大體上與淬火相同，即把鑄造出來的錳鋼破碎板加熱到1000～1100℃后在水中快速冷卻。
水韌處理后可以得到均勻的金相組織，并使金相組織固定下來，避免了在使用中自然發(fā)生相變而使性能變差。。我公司先后與國(guó)內(nèi)鐵建集團(tuán)，中鐵一局中鐵二局中鐵六局中鐵十一局中鐵十六局中鐵十八局中鐵十九局中鐵二十局駐非洲安哥拉工程處中鐵二。該系列顎式碎石機(jī)破碎方式為曲動(dòng)擠壓型，電動(dòng)機(jī)驅(qū)動(dòng)皮帶和皮帶輪，通過偏心軸使動(dòng)顎上下運(yùn)動(dòng)，當(dāng)動(dòng)顎上升時(shí)肘板和動(dòng)顎間夾角變大，從而推動(dòng)動(dòng)顎板向定顎板接近，與此同時(shí)物料被擠壓搓碾等多重破碎；當(dāng)動(dòng)顎下行時(shí)，肘板和動(dòng)顎間夾角變小，動(dòng)顎板在拉桿彈簧的作用下離開定顎板，此時(shí)已破碎物料從破碎腔下口排出，隨著電動(dòng)機(jī)連續(xù)轉(zhuǎn)動(dòng)碎石機(jī)動(dòng)顎作周期性的壓碎和排料，實(shí)現(xiàn)批量生產(chǎn)。

另外，在適配器上有一個(gè)毛氈墊，它起回收泵油的作用，如果它吸油已滿，真空泵也會(huì)發(fā)生滲油。新型反擊式碎石機(jī)構(gòu)簡(jiǎn)單、生產(chǎn)效率高、安裝簡(jiǎn)單、維修方便、設(shè)備和維護(hù)費(fèi)用較低等特點(diǎn)。廣泛應(yīng)用于選礦、修路、建筑和化學(xué)工業(yè)生產(chǎn)中，能夠?qū)σ恍﹫?jiān)硬和中硬石料進(jìn)行粗、中破碎，其中破碎比可以達(dá)到12以上。黎明重工機(jī)械的反擊式碎石機(jī)主要優(yōu)勢(shì)體現(xiàn)在：生產(chǎn)的反擊式碎石機(jī)采用無鍵連接，使設(shè)備整體強(qiáng)度高，使用方便，維修率低，可調(diào)整成品規(guī)格大小等特點(diǎn)。
