【正文】 籠式破碎機；反擊式破碎機。當物料的彎曲應力達到物料的彎曲強度時，即被折斷而破碎。篩上物料進入旋回破碎機2里、經(jīng)過破碎后，所得產(chǎn)品與1號篩下物料都落到振動篩3上，經(jīng)篩分后，篩上物料進入中碎圓錐破碎機(簡稱中碎機)，篩下物料落到振動篩5上。破碎與破碎機械本文主要論述了破碎的基本概念，介紹了常用的破碎機械的原理和技術(shù)、破碎機械的使用范圍和選擇，對雙輥式破碎機作了詳細的敘述，并介紹了破碎機的使用。這種破碎機采用了液壓控制系統(tǒng)，在破碎機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。Gearmatic破碎機的結(jié)構(gòu)特點是：采用Mally公司研制的抗拉強度很高的齒輪傳動裝置，為防塵而采用了良好的密封裝置。該公司還制造用于粗碎、中碎和細碎多種型式的轉(zhuǎn)子式破碎機，有SMD85A和SMD86A；。其規(guī)格分別為36英寸54英寸和48英寸66英寸。在每種多籠式破碎機中，都有以相反方向旋轉(zhuǎn)的(沿直線和中心給料點)4或6個同心籠室。允許的給料粒度達380，生產(chǎn)能力超過600。該公司制造的這種沖擊式破碎機可用于破碎白云石、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。驅(qū)動功率為75～500馬力，生產(chǎn)能力可高達美國HewittRobins公司正在生產(chǎn)雙輥式和三輥式破碎機、沖擊式破碎機及錘式破碎機。該機裝有與機架相連接的雙曲柄（肘板）裝置，從而保證了破碎力的合理分布。該公司制造的Mclanahan旋轉(zhuǎn)碎煤機，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。QK公司制造的中碎錘式破碎機，有10種規(guī)格，用于破碎軟到中硬物料或粗碎水泥原料，電動機功率為30～400，破碎生產(chǎn)率為20～280。用于細粒礫石的破碎，產(chǎn)品粒度為50。用該式計算破碎比很方便，因在生產(chǎn)中不可能經(jīng)常對大批物料作篩分分析，但采用該式，只要知道破碎機給料口和排料口寬度，就可計算出破碎比。2) 劈碎 將物料置于一個平面及一個帶尖棱的工作平面之間，當帶尖棱的工作平面對物料擠壓時，物料將沿壓力作用線的方向劈碎。 根據(jù)破碎方式、機械的構(gòu)造特征(動作原理)來劃分的，破碎機械大體上分為六類。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，當增加墊片時兩輥輪間隙變大，當減少墊片時兩輥輪間隙變小，出料粒度變小。如果是干油潤滑，應定期檢查并注入新油。4) 采用電子定量喂料秤—熒光分析儀—電子計算機自動調(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。——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 second type is used in stave hard materials and so on iron ore, fever stone, slag and coke.This pany making the Sand breaker is suitable for the reduction ratio big situation. This pany has also made the heavy intermediate crusher, using in the stave pebbles or the difficult garrulous rock.VoestAlpine Corporation has also made one kind of Centro breaker, and this machine is loaded with the high speed turbine type rotor, which is used in the grit gravel stave, and the product granularity is 50. This machine concentrates by upside giving the material, and the material to the rigid stave cavity wall direction movement. The rotor has the wearing 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。水泥工業(yè)使用的最大管磨機為，電機功率達8700。在操作時，應遵循操作規(guī)程，防止違章造成人機事故。目前，選廠粗碎多用鄂式破碎機或旋回圓錐破碎機；中碎采用標準型圓錐破碎機；細碎采用短頭型圓錐破碎機；粗磨用棒磨機、細磨用球磨機。一般來說磨礦機所處理的物料較細，產(chǎn)品粒度是細粒，甚至還要細些。旋回破碎機為一段破碎(一次破碎)。由于各國的習慣不同，最大粒度取值方法不同。第一種機型用于破碎石灰石、石膏、珍珠巖等物料；第二種機型用于破碎硬的鐵礦石、燒結(jié)石、爐渣和焦炭等物料。該公司制造的Titan破碎機，所能破碎的物料類似于Mammut型破碎機，但給料粒度為1200～2300，生產(chǎn)能力為220～1200，驅(qū)動功率為2170～2900。這種破碎機可將原煤或其他物料破碎到15以下。該機有9種規(guī)格，其生產(chǎn)能力可達1650，產(chǎn)品粒度為0～15。APP2030型粗碎機和APKM1630型中碎機是兩種大型的沖擊式破碎機，現(xiàn)已交付英國采石場使用。轉(zhuǎn)子的通路要襯裝碳化鎢導向板，從而破碎腔的上部和底部要安裝鑄造襯板。特別值得指出的是這幾種破碎機的破碎效率高，能耗小。物料的輸送是從料斗經(jīng)中央分配器送到破碎腔內(nèi)快速旋轉(zhuǎn)的轉(zhuǎn)子上的。英國GEC公司制造的Dyad雙轉(zhuǎn)子擺動錘式破碎機，生產(chǎn)能力高達1000。而特殊高速大型錘式破碎機的轉(zhuǎn)數(shù)為1800。該機裝有間隙調(diào)節(jié)裝置和輥子彈性保護裝置。該公司制造的齒輥破碎機共有13種規(guī)格，最小型的齒輥破碎機，驅(qū)動功率為237，其生產(chǎn)能力為150～200，產(chǎn)品粒度為50；最大型齒輥破碎機，驅(qū)動功率為2600，生產(chǎn)能力為2400～3000，產(chǎn)品粒度為300～400。澳大利亞VoestAlpine公司制造兩種型式的雙輥破碎機。它表示破碎后原料減小的程度。篩上不合格的物料進入細碎機6，其產(chǎn)品返回到振動篩5，而篩下合格品落入料倉7里，然后進入球磨機8。破碎機一般處理較大塊的物料，產(chǎn)品粒度較粗，通常大于8。 C、離心磨礦機：利用高速旋轉(zhuǎn)部件和介質(zhì)產(chǎn)生產(chǎn)離心力來完成破碎作用。破碎機的給料必須是連續(xù)均勻的，防止過載，而且在整個給料口寬度上給料量應一致，這樣可使破碎機受到的磨碎均勻，相對地延長易磨損零件的壽命。除了以上的五點外，對破碎機的安裝，既要保證牢固可靠，位置正確，又要注意防振要求，并把可調(diào)部位調(diào)至適當位置。s quarry from English Peabody Holmes. The APP2030 bulldozer and the APKM1630 intermediate crusher are two kinds of largescale impact type breakers, presently pays the English quarry use. Two equipment contract prices are 125 pounds (in contract including supplies electric drive equipment, specialpurpose speed control equipment and energy recycling installment).At present several hundreds Hazemag impact type breakers have been used in the limestone and other mines. In which majority breakers productivity has all surpassed for 500.American HewittRobins Corporation is producing the double rolls type and three rolls type breaker, the impact type breaker and the hammer type breaker. The double rolls type breaker is used in the process load big work, its productivity surpasses for 810, this machine has used the hydraulic pressure crushing roller installment, and the overload protection spring and the oak rubber tire drive type. This pany produces 24 inches48 inches three rolls both sides coal washing used the breaker, and has the small crushing roller hydraulic unit and the belt pulley drive. Productivity (stave product granularity is when 2 inches) may amount to for 320 .The HewittRobins impact type breaker is one kind of high efficiency, big the reduction ratio impact type breaker. Its specification respectively is 36 inches54 inches and 48 inches66 inches. This machine productivity is decided by the riddle through whole size. When the riddle clear size of opening is inches, its productivity may amount to for 900.This pany also makes two kinds of specifications the hammer type breakers, namely: 36 inches 32 inches and 48 inches32 inches, its riddle lattice bar and the spacing all are adjustable. This kind of hammer type breaker productivity may amount to for 190, the rotati
