【正文】 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 width。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。在破碎機(jī)工作時，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裝置松動等，并采取適當(dāng)?shù)拇胧┘右韵?。該系列對雙輥破碎機(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)動裝置等部分組成。但有的機(jī)械是同時兼有碎礦與磨礦作用，如自磨機(jī)。整個流程也可稱為粗碎段、中碎段、細(xì)碎段及模碎段。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。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。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)動功率為22～2000。對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)。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。目前已有數(shù)百臺Hazemag沖擊式破碎機(jī)在石灰石和其他礦山上使用。這種破碎機(jī)的轉(zhuǎn)子，可用2個或3個部件組成兩種型式的轉(zhuǎn)子。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)。英國Groft Barmac公司制造的Rotopactor破碎機(jī)， 是一種具有獨特形式的三級沖擊式破碎機(jī)。破碎產(chǎn)品的粒度從20到200網(wǎng)目。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。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。該公司制造的二段四輥破碎機(jī)是由兩臺雙輥破碎機(jī)組裝而成的。這種破碎機(jī)用于破碎中硬或是軟物料。2) 破碎比衡量破碎機(jī)的破碎效果，常用破碎比這個概念。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。5) 磨碎(研磨)物料與運動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，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。 (6) 其他類型的破碎磨礦機(jī) A、輥磨機(jī)：借轉(zhuǎn)動的輥子將物料碾碎。對已起動的破碎機(jī)，應(yīng)先空轉(zhuǎn)幾分鐘，空轉(zhuǎn)時可以檢查基座、防護(hù)板鏈等，如無異常，開始給料。檢查破碎機(jī)保險裝置，使之保持良好狀態(tài)。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。 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 part (or medium) contacts mutually, uses the medium is the steel ball, the steel rod, the broken stone or the ore block and so on. But some machineries are simultaneously have at the same time the garrulous ore and the rubbing function, like autogenously tumbling mill. The rice autogenously tumbling mill processing ore granularity upper limit may amount to 350~400, product degree of fineness reaches 100~200 goals to account for about 40%.The stave machinery which according to the stave way,the machinery structure characteris。在先進(jìn)的工業(yè)化國家，微米級超細(xì)粉碎設(shè)備已過渡了其發(fā)明時期，而進(jìn)入成熟、配套、完善的階段，設(shè)備研究朝著亞微米級超細(xì)粉碎和微米級精密分級的方向發(fā)展。破碎機(jī)停機(jī)時，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。對一些大型破碎機(jī)，有時還須借助外力起動。屬于這一類的又可分為：錘碎機(jī)；
