【正文】 ulic unit.West German PHBWeserhutte(PWH) Corporation makes the single roll and the double rolls breaker, and its crushing roller may be the smooth roll, perhaps on the garrulous roller the chamfer, and is loaded with the stave tooth. This kind of breaker is used in stave hard or the soft material.The PWH single rotor hammer type breaker of the pany also is used in stave as softly as the hard material, and has the very high reduction ratio, and may cause the stave product the granularity to be smaller than 3 millimeters.Australian VoestAlpine Corporation makes two patterns the double rolls breaker. One kind is loaded with the adjustment crushing roller gap mechanism and the elastic unloading roller. Two pattern breakers both may accord the different need, installing the first tone roller, the ripple roller and the serrated roller separately. The first type is used in stave materials and so on limestone, gypsum, pearlier。附錄BDevelopment survey of roller type breaker,impact type breaker and hammer type breakerThe roller type breaker, the impact type breaker and the hammer type breaker application scope is extremely widespread, can to each kind of different degree of hardness, the viscosity and the humidity all big material carries on thick garrulous, is garrulous and is in broken bits. 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。同時(shí),也在采取積極措施盡量降低磨損件的磨耗。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。電功率達(dá)7000以上,臺(tái)時(shí)產(chǎn)量300以上。檢查破碎機(jī)保險(xiǎn)裝置,使之保持良好狀態(tài)。萬一出現(xiàn)事故停機(jī),也應(yīng)將機(jī)中物料清除后,才能重新啟動(dòng)。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。還應(yīng)防止堅(jiān)硬物料如錘頭及角鐵之類落入機(jī)內(nèi)。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。首先應(yīng)開動(dòng)油泵與冷卻系統(tǒng),經(jīng)過3~5分鐘后,待右路暢通在啟動(dòng)破碎機(jī)電動(dòng)機(jī)。 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。 各類破碎機(jī)破碎機(jī)有不同的規(guī)格,不同的使用范圍。 (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?(3) 輥式破碎機(jī)礦塊在兩個(gè)相向旋轉(zhuǎn)的圓輥夾縫中,主要受到連續(xù)的壓碎作用,但也帶有磨剝作用,齒形輥面還有劈碎作用。 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。破碎機(jī)又可分為粗碎機(jī)、中碎機(jī)和細(xì)碎機(jī)。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。3) 折碎 物料受彎曲應(yīng)力作用而破碎。 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。 這個(gè)流程中、細(xì)碎機(jī)為閉路破碎,旋回與中碎機(jī)斗式開路破碎。經(jīng)篩分后,篩上物料再進(jìn)入細(xì)碎圓錐破碎機(jī)(簡稱細(xì)碎機(jī))里。這種方法求得的破碎比,能較能真實(shí)地反映破碎程度,因而理論研究常采用它。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。① 用破碎前物料的最大粒度與破碎后產(chǎn)品最大粒度之比計(jì)算 式中 ——破碎前物料的最大粒度; ——破碎后物料的最大粒度。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。生產(chǎn)能力約為50,這種破碎機(jī),適用于破碎0~5粒級(jí)占80%的砂石。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。兩種型式的破碎機(jī)都可以根據(jù)不同的需要,分別安裝上平輥、波紋輥和齒形輥。這種破碎機(jī)用于破碎中硬或是軟物料。通過破碎錘的旋轉(zhuǎn),將物料拋射到破碎腔壁上,使其受沖擊而破碎。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)。這種破碎機(jī)共有12種規(guī)格:給料粒度為0~25,驅(qū)動(dòng)功率為100~3500。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。該機(jī)能在一次運(yùn)轉(zhuǎn)作業(yè)中同時(shí)完成破碎和篩分兩個(gè)作業(yè)。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。一臺(tái)二段三輥破碎機(jī)能代替兩臺(tái)獨(dú)立的破碎機(jī)所能完成的破碎作業(yè)。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。蘇聯(lián)Machinoexport公司生產(chǎn)的沖擊式破碎機(jī),用于破碎中等硬度的耐磨礦石。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。PEG型沖擊式破碎機(jī)是用來粗碎像石灰石和石膏之類的礦物。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。生產(chǎn)能力(破碎產(chǎn)品粒度為2英寸時(shí))可達(dá)320。其中大多數(shù)破碎生產(chǎn)能力都超過了500。由英國Peabody Holmes公司銷售到整個(gè)英國的采石場(chǎng)。破碎產(chǎn)品的粒度從20到200網(wǎng)目。MⅠ型破碎機(jī)是一種小型破碎機(jī),生產(chǎn)率為50。該公司生產(chǎn)的這種破碎機(jī)系列有五種規(guī)格。破碎腔的磨損很小,但對(duì)破碎區(qū)域還是要進(jìn)行專門的耐磨保護(hù)。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)。破碎產(chǎn)品粒度在40以下,生產(chǎn)能力為15~150。該機(jī)的系列產(chǎn)品有:(轉(zhuǎn)子為1 ),(11),()三種規(guī)格。附錄A輥式破碎機(jī)、沖擊式破碎機(jī)和錘式破碎機(jī)的發(fā)展概況輥式破碎機(jī)、沖擊式破碎機(jī)和錘式破碎機(jī)的應(yīng)用范圍非常廣泛,能對(duì)各種不同硬度的、粘度和濕度都較大的物料進(jìn)行粗碎、中碎和細(xì)碎。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)。實(shí)際上,該機(jī)最適合破碎塊狀物料,不適合破碎片狀物料。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。破碎產(chǎn)品落入排料槽內(nèi)。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。Groft公司最近安裝使用的一臺(tái)MⅢ型破碎機(jī),裝有雙驅(qū)動(dòng)裝置和兩臺(tái)200馬力的電動(dòng)機(jī),其生產(chǎn)率超過200。每個(gè)籠室都有一排沖擊破碎棒。西德Hazemag公司制造的Hazemag型沖擊破碎機(jī)。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。該公司生產(chǎn)的24英寸48英寸三輥兩端洗煤用破碎機(jī),具有較小的破碎輥液壓裝置
