【正文】 ring capacity smallest structure and the best stave effect. Productivity is about 50 tons/hour, this kind of breaker, is suitable in the stave 0～5 grade occupies 80% sand and crushed stone. This machine has two kinds of specifications: 12501250 and 16001600, the actuation power is 5575.Stave and stave machineryThis article mainly elaborated the stave basic concept, introduced the monly used stave machinery principle and technical, the stave machinery use scope and the choice, has made the detailed narration to the double roll type breaker, and introduced the breaker use.1 Stave, the reduction ratio and the crushing circuit1) Break Under the exogamic process, causes the material pellet to split the finely ground particles process, is called stave or the smashing. 2) Reduction ratio Weighs the breaker the stave effect,monly used reduction ratio this concept. After the breaker reduction ratio is raw material granularity and the stave product precision ratio of. It after expressed the stave raw material reduces degree.The reduction ratio has the following several putational method.① Of the material ratio of greatest granularity and the stave product greatest granularity calculates after stave in front ofIn this in the formula ——Stave front material greatest granularity。③ The high speed movement material attacks mutually。——Guaranteed the breaker bites the material the effective width is a material.The dump mouth width value, the thick breaker takes the maximum dump mouth width。 the machine structural style divides into the enclosed type and the opens type.Croft Corporation recently installed the use the MⅢ breaker, which is loaded with the double drives and two 200 horsepower electric motors,its productivity surpasses for 200. The MⅠbreaker is one kind of small breaker, the productivity is 50.American Eagle Corporation makes the Maxim multicage type breaker, which is used in mixing the material stave. In each kind of cage type breaker, all has by reverse direction revolving (gives material along straight line and center) 2, 4 or 6 concentric cage rooms. Each cage room all has a row of impact stave stick. Stave product granularity from 20 to 200 meshes. This kind of breaker has three kinds of specifications, the stave productivity is 7~30 tons/hour, 15~60 and 30~110.English GEC Corporation makes the Dyad double rotors swinging hammer type breaker, productivity reaches as high as for 1000.West German Hazemag Corporation makes Hazemag impact breaker. Corporation sells the entire England39。4) 采用電子定量喂料秤—熒光分析儀—電子計(jì)算機(jī)自動(dòng)調(diào)節(jié)系統(tǒng)，控制原料配料，為入窯生料成分均勻穩(wěn)定創(chuàng)造條件。除去日常維護(hù)工作外，還應(yīng)對(duì)破碎機(jī)及其附屬設(shè)備如潤(rùn)滑冷卻系統(tǒng)進(jìn)行定期檢修，例如小修、中修、大修等。如果是干油潤(rùn)滑，應(yīng)定期檢查并注入新油。若是新安裝的破碎機(jī)，應(yīng)使其空轉(zhuǎn)時(shí)間長(zhǎng)一些，可空轉(zhuǎn)兩到三個(gè)工作班后再加料。墊片裝置是通過增減墊片的數(shù)量或厚薄來調(diào)節(jié)出料粒度大小的，當(dāng)增加墊片時(shí)兩輥輪間隙變大，當(dāng)減少墊片時(shí)兩輥輪間隙變小，出料粒度變小。 B、盤磨機(jī)：利用垂直軸或水平軸的圓盤轉(zhuǎn)動(dòng)作為破碎部件。 根據(jù)破碎方式、機(jī)械的構(gòu)造特征(動(dòng)作原理)來劃分的，破碎機(jī)械大體上分為六類。 3 破碎機(jī)的分類和使用范圍破碎機(jī)的使用范圍由于類別的不同而不同，根據(jù)破碎機(jī)作用的方式可以將破碎機(jī)粗略地分為兩大類，破碎機(jī)和磨礦機(jī)。2) 劈碎 將物料置于一個(gè)平面及一個(gè)帶尖棱的工作平面之間，當(dāng)帶尖棱的工作平面對(duì)物料擠壓時(shí)，物料將沿壓力作用線的方向劈碎。這樣，振動(dòng)篩5既是預(yù)先篩分又是檢查篩分，檢查篩分的作用，是破碎機(jī)排料進(jìn)行篩分，其篩分尺寸大致等于預(yù)先篩分篩孔尺寸。用該式計(jì)算破碎比很方便，因在生產(chǎn)中不可能經(jīng)常對(duì)大批物料作篩分分析，但采用該式，只要知道破碎機(jī)給料口和排料口寬度，就可計(jì)算出破碎比。破碎機(jī)的破碎比就是原料粒度與破碎后產(chǎn)品精度之比。用于細(xì)粒礫石的破碎，產(chǎn)品粒度為50。該公司制造的PWH單轉(zhuǎn)子錘式破碎機(jī)，也是用于破碎軟到中硬物料的，并且有很高的破碎比，可使破碎產(chǎn)品的粒度小于3。QK公司制造的中碎錘式破碎機(jī)，有10種規(guī)格，用于破碎軟到中硬物料或粗碎水泥原料，電動(dòng)機(jī)功率為30～400，破碎生產(chǎn)率為20～280。盧森堡MecanArbed公司制造的大型Arbed齒輥破碎機(jī)，用于粗碎或中碎作業(yè)，破碎脆性或中硬物料（且含濕度大和粘性高的物料）。該公司制造的Mclanahan旋轉(zhuǎn)碎煤機(jī)，裝有鉆孔篩板，用于破碎軟煤餓中等硬度的煤，生產(chǎn)能力非常大。齒輥可以是鈍刃型或者是平緩的椎體型，鈍刃型齒輥的允許給料粒度大。該機(jī)裝有與機(jī)架相連接的雙曲柄（肘板）裝置，從而保證了破碎力的合理分布。這種錘式破碎機(jī)的生產(chǎn)能力可達(dá)190，轉(zhuǎn)數(shù)為1350。美國(guó)HewittRobins公司正在生產(chǎn)雙輥式和三輥式破碎機(jī)、沖擊式破碎機(jī)及錘式破碎機(jī)。這種破碎機(jī)有三種規(guī)格，破碎生產(chǎn)率為7～15～60和30～110。驅(qū)動(dòng)功率為75～500馬力，生產(chǎn)能力可高達(dá)破碎作業(yè)時(shí)，物料以一定的加速度進(jìn)入破碎腔內(nèi)轉(zhuǎn)子與側(cè)壁之間，從而產(chǎn)生沖擊破碎。該公司制造的這種沖擊式破碎機(jī)可用于破碎白云石、硅質(zhì)石灰?guī)r等礦石，但不能破碎濕度和粘性都很大的物料。目前的輥式破碎機(jī)、沖擊式破碎機(jī)和錘式破碎機(jī)在設(shè)計(jì)、制造和應(yīng)用上都取得了一些新的進(jìn)展。允許的給料粒度達(dá)380，生產(chǎn)能力超過600。轉(zhuǎn)子的表面硬度要求極高。在每種多籠式破碎機(jī)中，都有以相反方向旋轉(zhuǎn)的(沿直線和中心給料點(diǎn))4或6個(gè)同心籠室。兩臺(tái)設(shè)備的合同價(jià)格是125英鎊（合同中包括供給的電力驅(qū)動(dòng)裝置、專用的速度控制設(shè)備和能量回收裝置）。其規(guī)格分別為36英寸54英寸和48英寸66英寸。該公司制造的PEF型沖擊式破碎機(jī)的給料粒度很小，產(chǎn)品粒度為0～44。該公司還制造用于粗碎、中碎和細(xì)碎多種型式的轉(zhuǎn)子式破碎機(jī)，有SMD85A和SMD86A；。該公司制造的單輥破碎機(jī)，用于破碎巖石、礦石、碎石、煤和硬油母頁(yè)巖特別有效。Gearmatic破碎機(jī)的結(jié)構(gòu)特點(diǎn)是：采用Mally公司研制的抗拉強(qiáng)度很高的齒輪傳動(dòng)裝置，為防塵而采用了良好的密封裝置。該公司制造的沖擊式破碎機(jī)，有18種規(guī)格。這種破碎機(jī)采用了液壓控制系統(tǒng)，在破碎機(jī)的后部排料口處裝有格篩和用于拆卸與安裝破碎錘的液壓裝置。該公司制造的Sand破碎機(jī)適用于破碎比大的場(chǎng)合。破碎與破碎機(jī)械本文主要論述了破碎的基本概念，介紹了常用的破碎機(jī)械的原理和技術(shù)、破碎機(jī)械的使用范圍和選擇，對(duì)雙輥式破碎機(jī)作了詳細(xì)的敘述，并介紹了破碎機(jī)的使用。英美以物料80％能通過篩孔的篩孔寬度為最大粒度直徑，原蘇聯(lián)以物料的95％能通過篩孔的篩孔寬度為最大粒度的直徑。篩上物料進(jìn)入旋回破碎機(jī)2里、經(jīng)過破碎后，所得產(chǎn)品與1號(hào)篩下物料都落到振動(dòng)篩3上，經(jīng)篩分后，篩上物料進(jìn)入中碎圓錐破碎機(jī)(簡(jiǎn)稱中碎機(jī))，篩下物料落到振動(dòng)篩5上。中碎機(jī)為二段破碎(二次破碎)，細(xì)碎機(jī)為三段破碎(三次破碎)。當(dāng)物料的彎曲應(yīng)力達(dá)到物料的彎曲強(qiáng)度時(shí)，即被折斷而破碎。其結(jié)構(gòu)特征是破碎部件(或介質(zhì))互相接觸，所采用的介質(zhì)是鋼球、鋼棒、礫石或礦塊等。屬于這一類的又可分為：錘碎機(jī)；籠式破碎機(jī)；反擊式破碎機(jī)。 4 雙輥破碎機(jī)的具體介紹雙輥破碎機(jī)適用于在水泥、化工、電力、冶金、建材、耐火材料等工業(yè)部門破碎中等硬度的物料，如石灰石，爐渣 ，焦炭，煤等物料的中碎，細(xì)碎作業(yè)。對(duì)一些大型破碎機(jī)，有時(shí)還須借助外力起動(dòng)。3) 破碎機(jī)工作時(shí)的檢查及看護(hù)。破碎機(jī)停機(jī)時(shí)，要檢查緊固螺栓是否牢固和易磨損部分的磨損程度，是否需要更換。立式磨系列中磨盤直徑已達(dá)5以上，電機(jī)功率5000以上，臺(tái)時(shí)產(chǎn)量500以上。在先進(jìn)的工業(yè)化國(guó)家，微米級(jí)超細(xì)粉碎設(shè)備已過渡了其發(fā)明時(shí)期，而進(jìn)入成熟、配套、完善的階段，設(shè)備研究朝著亞微米級(jí)超細(xì)粉碎和微米級(jí)精密分級(jí)的方向發(fā)展?！狝fter stave material greatest granularity.Because the various countries39。 ④ High speed movement work body to hanging material impact.5) Grinds (attrition)After the material and between the movement active face certain pressure and the cutting action of force, its shear stress achieved when material shearing strength limit, the material then crushes, or between material each other rubs when the cutting, the grinding function causes the material to be stave.3 Breaker classifications and use scopeThe breaker use scope as a result of the category difference and the difference, may divide into sketchily according to the breaker function way the breaker two big kinds, the breaker and the ore mill.The breaker general processing bulk material, the product granularity is thick, usually is bigger than 8. Its structure characteristic is between stave has certain gap, contacts not mutually. The breaker may divide into the bulldozer, the intermediate crusher and the small aggregate crusher. Generally speaking the ore mill processes the material is thin, the product granularity is the fine grain, may amount to , even also wants thin. Its structure characteristic is the stave
