This kind of crusher stave efficiency is especially high, the energy consumption is small. At present overseas in the roller type breaker, the impact type breaker and in the hammer type breaker design, the manufacture and the application has all made some new progress.English Babbitless (GB) Corporation has made one kind of stave scaled height of burst, the energy consumption low Dragon impact type breaker. This machine series product includes: (rotor is ), (11), () three kinds of specifications.This pany makes this kind of impact type breaker available in stave dolomite, ore and so on silicon nature limestone, but cannot break the humidity and the coherent all very big material. For the material granularity is 65~ fact, this machine most suits the stave massive material, does not suit the stave laminated material. The stave product granularity below 40, productivity is 15~150.This pany has also made the impact type breaker which 13 kinds may reverse. The permission amounts to 380 for the material granularity, productivity surpasses for 600.This pany also has produced 6 kinds of specifications type breaker, productivity is 35~195, the product granularity is 6~50.English Groft Barmac Corporation makes the Rotopactor breaker, is one kind has the unique form three levels of impact type breaker. When stave work, the material enters in the stave cavity by certain acceleration between the rotor and the sidewall, thus has the impact to be staving. The material transportation is delivers in the stave cavity from the hopper after the central divider on the fast revolving rotor. The stave product falls in the dump trough. The stave cavity attrition is very small, but must carry on the special wearresisting protection to the stave region. The rotor circuit must lining the attire tungsten carbide guidance board, thus stave cavity upside and the base must install the casting backing. The rotor skin hardness request is extremely high. This kind of breaker rotor, available 2 or 3 parts pose two patterns the rotors.This pany produces this kind of breaker series has five kinds of specifications. The actuation power is 75~500 horsepower, productivity may reach as high as for 250. This kind of breaker drive may carry on the modification。3) 磨機(jī)與新型高效分離設(shè)備和輸送設(shè)備相匹配，組成各種新型干法閉路粉磨系統(tǒng)，以提高粉磨效率，增加粉磨功的有效利用。檢查破碎機(jī)保險(xiǎn)裝置，使之保持良好狀態(tài)。同時(shí)注意軸承溫度不宜超過50℃，正常油溫應(yīng)在30～35℃左右，為了保證潤滑油的質(zhì)量，應(yīng)定期清洗油箱，排出污染物。對(duì)已起動(dòng)的破碎機(jī)，應(yīng)先空轉(zhuǎn)幾分鐘，空轉(zhuǎn)時(shí)可以檢查基座、防護(hù)板鏈等，如無異常，開始給料。 雙輥破碎機(jī)出料粒度的調(diào)節(jié)：兩輥輪之間裝有楔形或墊片調(diào)節(jié)裝置，楔形裝置的頂端裝有調(diào)整螺栓，當(dāng)調(diào)整螺栓將楔塊向上拉起時(shí)，楔塊將活動(dòng)輥輪頂離固定輪，即兩輥輪間隙變大，出料粒度變大，當(dāng)楔塊向下時(shí)，活動(dòng)輥輪在壓緊彈簧的作用下兩輪間隙變小，出料粒度變小。 (6) 其他類型的破碎磨礦機(jī) A、輥磨機(jī)：借轉(zhuǎn)動(dòng)的輥?zhàn)訉⑽锪夏胨椤?米自磨機(jī)處理礦石粒度上限可達(dá)350～400，產(chǎn)品細(xì)度達(dá)100～200目的占40%左右。5) 磨碎(研磨)物料與運(yùn)動(dòng)的工作表面之間受一定的壓力和剪切力作用后，其剪切應(yīng)力達(dá)到物料的剪切強(qiáng)度極限時(shí)，物料便粉碎，或物料彼此之間摩擦?xí)r的剪切、磨削作用而使物料破碎。 2 破碎機(jī)械的主要工作原理由于物料顆粒的形狀是不規(guī)則的，而且物料的物性不同，所以采用的粉碎方法也不同，利用機(jī)械力粉碎物料按施加外力不同有如下幾種方法：1) 壓碎 將物料置于兩塊工作面之間，施加壓力后，物料因壓應(yīng)力達(dá)到其抗壓強(qiáng)度而破碎，這種方法一般使用于破碎大塊物料。經(jīng)篩分后，篩上物料再進(jìn)入細(xì)碎圓錐破碎機(jī)(簡(jiǎn)稱細(xì)碎機(jī))里。排料口寬度的取值，粗破碎機(jī)取最大排料口寬度；中破碎機(jī)取最小排料口寬度。2) 破碎比衡量破碎機(jī)的破碎效果，常用破碎比這個(gè)概念。VoestAlpine公司還制造了一種Centro破碎機(jī)，該機(jī)裝有高速透平式轉(zhuǎn)子。這種破碎機(jī)用于破碎中硬或是軟物料。該公司制造的HBK型錘式破碎機(jī)，主要用于破碎筑路工程需要的碎石（中硬到堅(jiān)硬）。該公司制造的二段四輥破碎機(jī)是由兩臺(tái)雙輥破碎機(jī)組裝而成的。二段三輥破碎機(jī)的破碎輥在標(biāo)準(zhǔn)速度下，生產(chǎn)能力為75～600。該公司制造的DDZW1512型雙齒輥破碎機(jī)，用于破碎強(qiáng)度高達(dá)200的物料，其破碎生產(chǎn)能力為50～150。KHD公司制造的WB25型雙輥破碎機(jī)，適用于破碎中等硬度物料。該公司還制造兩種規(guī)格的錘式破碎機(jī)，即：36英寸32英寸和48英寸32英寸，其格篩的格條和間距都是可調(diào)的。其中大多數(shù)破碎生產(chǎn)能力都超過了500。破碎產(chǎn)品的粒度從20到200網(wǎng)目。該公司生產(chǎn)的這種破碎機(jī)系列有五種規(guī)格。英國Groft Barmac公司制造的Rotopactor破碎機(jī)， 是一種具有獨(dú)特形式的三級(jí)沖擊式破碎機(jī)。該機(jī)的系列產(chǎn)品有：(轉(zhuǎn)子為1 )，(11)，()三種規(guī)格。英國Babbitless(GB)公司制造了一種破碎比高、能耗低的Dragon沖擊式破碎機(jī)。該公司還生產(chǎn)了6種規(guī)格的輥式破碎機(jī)，生產(chǎn)能力為35～195，產(chǎn)品粒度為6～50。這種破碎機(jī)的轉(zhuǎn)子，可用2個(gè)或3個(gè)部件組成兩種型式的轉(zhuǎn)子。每個(gè)籠室都有一排沖擊破碎棒。目前已有數(shù)百臺(tái)Hazemag沖擊式破碎機(jī)在石灰石和其他礦山上使用。該機(jī)的生產(chǎn)能力取決于格篩的通孔的尺寸，其生產(chǎn)能力可達(dá)900。該公司還制造了用于碎煤作業(yè)的PEK型沖擊式破碎機(jī)，還有10中規(guī)格，最大生產(chǎn)能力達(dá)2000。液壓裝置是用來釋放不可破碎的物料和在破碎腔堵塞時(shí)進(jìn)行卸載的。對(duì)于粘性高或濕度大的物料，其產(chǎn)品粒度比沖擊式破碎機(jī)的產(chǎn)品粒度還要細(xì)。當(dāng)破碎機(jī)運(yùn)行時(shí)，可改變動(dòng)輥的位置來調(diào)節(jié)產(chǎn)品的粒度。最大給料粒度為400～1600，生產(chǎn)能力為20～1800，破碎產(chǎn)品粒度為0～150，驅(qū)動(dòng)功率為22～2000。西德PHBWeserhutte（PWH）公司制造的單輥和雙輥破碎機(jī)，其破碎輥可以是平滑的光輥，或是在碎輥上刻槽，并裝有破碎齒。該公司還制造了重型中碎機(jī)，用于破碎卵石或難碎的巖石。1 破碎、破碎比和破碎流程1) 破碎在外力作用下，使物料顆粒分裂成更小顆粒的過程，稱為破碎或者粉碎。② 用破碎機(jī)給料口有效寬度和排料口寬度之比 式中 ——破碎機(jī)給料口寬度； ——破碎機(jī)排料口寬度；—— 保證破碎機(jī)咬住物料的有效寬度系料。從中碎機(jī)4排出的產(chǎn)品也落到振動(dòng)篩5上。整個(gè)流程也可稱為粗碎段、中碎段、細(xì)碎段及模碎段。4) 沖擊破碎 物料受沖擊力作用而破碎，由于其破碎力是瞬時(shí)作用的，其破碎效率高、破碎比大、能量消耗少，沖擊破碎有如下幾種情況：① 運(yùn)動(dòng)的物體對(duì)物料的沖擊；② 高速運(yùn)動(dòng)的物料向固定工作面沖擊；③ 高速運(yùn)動(dòng)的物料互相沖擊；④ 高速運(yùn)動(dòng)的工作體向懸空的物料沖擊。但有的機(jī)械是同時(shí)兼有碎礦與磨礦作用，如自磨機(jī)。 (5) 磨礦機(jī)礦石在旋轉(zhuǎn)的圓筒內(nèi)受到磨礦介質(zhì)(鋼球、鋼棒、礫石或礦塊)的沖擊與研磨作用而被粉碎。該系列對(duì)雙輥破碎機(jī)主要由輥輪、輥輪支撐軸承、壓緊和調(diào)節(jié)裝置以及驅(qū)動(dòng)裝置等部分組成。2) 破碎機(jī)的操作。在破碎機(jī)工作時(shí)，應(yīng)檢查破碎產(chǎn)物粒度是否符合要求，如發(fā)現(xiàn)超過規(guī)定粒度的顆粒過多，應(yīng)找出原因，如篩棒縫隙過大、排料口過寬、錘子、鄂板或齒輥等磨損過度或是保險(xiǎn)裝置松動(dòng)等，并采取適當(dāng)?shù)拇胧┘右韵?。?duì)齒輥破碎機(jī)，還應(yīng)該除掉齒牙間的木料。2) 采用預(yù)烘干(或預(yù)破碎)形式組成烘干(破碎)粉磨聯(lián)合機(jī)組。粉碎技術(shù)的發(fā)展主要表現(xiàn)在產(chǎn)品微細(xì)化、微粉功能化、設(shè)備自動(dòng)化、節(jié)能新工藝和設(shè)備及低污染高強(qiáng)度材料的應(yīng)用等方面。 custom is different, the greatest granularity value method is different. Britain and America take the material 80% can through the mesh width as the greatest granularity diameter, the former 95% be able to pass the mesh take the material the mesh width as the greatest granularity diameter.② Uses the breaker to the material mouth effective width and ratio of the dump mouth widthIn this in the formula ——The breaker gives the material mouth wi
