[Keywords]: construction machinery, Crusher, Working principle, Structure characteristics
Now the most common material crushing machine hubei type is broken.Machine and cone crusher, the crusher of stone of flake.A large proportion of material, the influence of the aggregate gradation, the cause of concrete qualityUnstable, make the road to ensure quality. At present already from Foreign introduced impact breaker (such as SVEDALA) companyB7100type impact breaker), the production function is broken the stone, the cube concrete production quality is very important.
1.Several crusher work characteristics and applications
Mandibles crusher is driven by two hubei plate transmission system periodically sports, rely on the working surface two broken tooth interlaced layout. Type will be crushed stone foils, discontinuous. And crushing efficiency is low,Energy consumption, worn parts, stone flake rate is high, grainLarge scope of degrees. But its simple structure, convenient maintenance, for hard mineral Have high crushing effect, so commonly used level.
On the cone crusher fixed cones and eccentric exercise within the cone will be crushed stone, it is a continuous breakage, production efficiency than hubei type Machine. But the cone crusher is a kind of mechanical parts, let wear easily, cause instability, grain products with large size and scope.For secondary crushing and less demanding on product at the end of the class.
Counterattack crusher is a continuous the mechanical broken. It will fight back, and centrifugal grinding, sheare and breaking principle of organic together, make its energy and crushing cavity fully and effectively with high efficiency, broken, a thin and even less vulnerable parts, maintenance, insurance keep convenience, low energy consumption. In the production of products and good shape of edges and corners, needle shape, size, and less commonly used for powder against the aggregate. At the end of the roadbed level, it can also be used for building materials, chemicals, mining and smelting.The fine gold industry. used in grinding finely greatly .The low grinding machine, the grinding materials in size and the efficacy of grinding.
2 The working principle of impact breaker
In industry, widely applied to the material crushing method is still mechanical force is broken, the main squeeze, splitting, breaking, polishing and impact crush etc. Mandibles crusher is near when moving hubei board periodically.When using extrusion action it will be installed in the material breakage during due to hubei board.For tooth type structure, the broken pieces, when both split and grinding. Round cone crusher cavity with extrusion, bending and concurrently abrasive. Material in the crushing cavity by huge extrusion
with more than material, when the extrusion pressure between particles of cohesion, the material being breakage. Breakage is a kind of impact breakage, namely the selectivity of material defect, not only save power and can guarantee the granularity, reduced powder breaking . In the moment, particles impact crushing beginning ,it stress wave generated internally, four newsletters and spread quickly in the internal defects, crack and grain interface, etc.The stress concentration, the first to face these particles fragile broken.
B7100 counterattacking crusher is based on breakage mechanism manufacturing .The original stone material from the machine, with the top into points hopper control gate ,and the original stone material paddle through a hopper bottom proportional with high-speed operation of the rotor, or through the mouth hopper flank a waterfall runs to fall into crushing cavity. The original stone material in the rotor speed to high speed by circle degree in centrifugal force, under the action of the rotor side by speed of 50-85to fly and export ,and from the points of stone material mouth dropped particles.The completely inelastic collision occurs, the stone was shattered and crushed .The other particle collisions, grinding, repeatedly in the cavity forming, more turbulent close crushing cavity wall, stone, smaller grain, speed, lower, soon
The stone particles will lose energy into finished hopper. during the break inner cavity near ,there is always a layer of small particles stone, low stone for crushing cavity provides a stone line. So crushing process
Is the material of interaction between the particle, namely “broken stone millstones”, it also called " stone broken stone", thus impact breaker was since naturally hamme. Because the particles are not direct with stone born and raised friction life-span of hammer.
3.counterattack crusher structure characteristics
B7100 type impact breaker mainly by crushing cavity, hopper cavity, distributor, rotor, transmission system, cover, base, motor, etc.Compared with other crusher, this machine has some characteristics in structure.
3.1 Parameters can be adjusted
Other crusher generally only adjust the size of the discharging port to change the grain size composition mouth the product quality, often with grain the liner wear different and different, mouth and product quality
Stability. While B7100 type crusher can counter through parameter adjust to change the final product size, ensure the quality of products.
2)The rotor speed of rotor diameter of adjustment.
Increase the rotor speed with the increasing speed or rotor diameter, can increase the stones. Kinetic energy time and improve production rate and increase the stones.
3)The flow of material supply
Distributor can control and adjustment the overflow ratio of the rotor and feed, change the grain size composition products.In the rotor speed, small when certain feeder, can increase the stone flow supply ,limit the stones of the cavity movement, shorten the collision.Stone particles in the crushing cavity retention time, improve the crusher after ability.
4) the original stone material for gradation of adjustment.
In the rotor speed and requirements,the finished product specifications for certain, change the size, will influence the finished product .The size of the material, partical size is small, finished product and small, For grain degrees are finished partical. Therefore, according to the finished product craig requirements, supply the appropriate material.
3.2 Maintain the security door 3.2 interlocking system
B7100 type crushers maintenance door lock on the door including maintenance,The door interlock, bolting structure, passage locks, traffic and keys,EMX control cabinet insurance lock, stopping key lock, etc.Some security protection equipment operation in order to prevent or stop after rotor yet fully stopped ，circumstances maintenance door is opened, still can prevent the equipment.In the process of inspection and maintenance of the closed door yet situations.
3.3 Unique structure of the crushing cavity
Breakage is a measure of the effect of crusher is an important standard, the design of B7100 type crusher cavity shape optimization improve crushing ratio.
Improve crushing ratio means it can reduce the number of crushing, save equipment usage investment. counterattack crusher cavity shape of B7100 type for crushing cavity heart optimization design, using the straight line, combining with the curve in the crushing cavity with have lugs device, make a rest angle stranded materials. From the rotor,the acceleration is under the rubble in centrifugal motion along the radial direction in broken,cavity wall form a layer of rock composed by the rubble. This layer stone line from the rubble of radial high-speed motion, it is the jostling the second "play" stone. On the times that the crushing machine more than 12-15,and the broken than traditional crusher is generally 3-5, type counterattack crusher is less broken than grinding ,it is a ideal equipment.
3.4 elaborate design of rotor
Opening the structure design of the rotor can withstand hard materials ，such as just jade, quartz of repeated impact and abrasion of the rotor. High abrasion resistance lining board and rotor blades that can use, avoid long rotor,after disassembly. The rotor with special plates o flateral resistant materials the protection board, can make the completely avoid the rotor caused by wear ,after the rotor failure, eliminate for repair difficulties caused economic losses. The dynamic load balancing test, high-speed rotor can smooth running.

目前常用的石料破碎機(jī)械大部分是鄂式破碎機(jī)和圓錐式破碎機(jī)，這種破碎機(jī)破碎的石料中片狀
料比例很大，這對(duì)骨料的級(jí)配影響很大，造成砼質(zhì)量不穩(wěn)定，使路面質(zhì)量難以得到保證。目前我國(guó)已從國(guó)外引進(jìn)了反擊式破碎機(jī)（如SVEDALA) 公司的B7100 型反擊式破碎機(jī)），此種破碎機(jī)能生產(chǎn)出近于立方體的石料，這對(duì)生產(chǎn)高質(zhì)量砼是至關(guān)重要的。
1 幾種破碎機(jī)的工作特點(diǎn)及應(yīng)用
鄂式破碎機(jī)是靠傳動(dòng)系統(tǒng)帶動(dòng)兩塊鄂板周期性運(yùn)動(dòng)，依靠破碎工作表面上兩塊相互交錯(cuò)布置的齒型襯板將石料壓碎，工作不連續(xù)。因而破碎效率低、能量消耗大、機(jī)件磨損嚴(yán)重，造成石料片狀率高，粒度范圍大。但其結(jié)構(gòu)簡(jiǎn)單，維修方便，對(duì)于堅(jiān)硬礦石有很高的破碎效果，因此常用作一級(jí)破碎。
圓錐破碎機(jī)依靠固定的外錐和偏心運(yùn)動(dòng)的內(nèi)錐將石料壓碎，是一種連續(xù)破碎，生產(chǎn)效率比鄂式破碎機(jī)高。但圓錐破碎機(jī)也是一種機(jī)械式破碎，機(jī)件容易磨損，造成產(chǎn)品粒型不穩(wěn)定，粒度范圍大，故常用作二級(jí)破碎以及對(duì)產(chǎn)品要求不太高的末級(jí)破碎反擊式破碎機(jī)是一種連續(xù)的非機(jī)械式破碎。它將打擊、反擊、離心沖擊、剪切、研磨等破碎原理有機(jī)結(jié)合在一起，使其能量和破碎空腔得到充分、有效利用，破碎效率高，出料細(xì)而均勻，易損零件少，維護(hù)保養(yǎng)方便，能耗低。生產(chǎn)的產(chǎn)品粒型好且呈棱角，針片狀少，粒度連續(xù)且粉末少，常用作對(duì)骨料要求較高的路基路面的末級(jí)破碎，也可用于建材、化工、礦山、冶金工業(yè)的細(xì)碎作業(yè)。用于磨前細(xì)碎時(shí)，可大幅度降低磨機(jī)的入磨物料粒度，起到以破代磨的功效。
2 反擊式破碎機(jī)的工作原理
在工業(yè)上，目前廣泛應(yīng)用的物料破碎方法仍是機(jī)械力破碎，主要有擠壓、劈碎、折斷、研磨和沖擊破碎等。鄂式破碎機(jī)是當(dāng)動(dòng)鄂板周期性地靠近定鄂板時(shí)，借助擠壓作用將裝于期間的物料破碎，由于鄂板為齒型結(jié)構(gòu)，破碎時(shí)兼有劈碎、折斷和磨碎作用。圓錐破碎機(jī)破碎腔以擠壓破碎為主，兼有彎曲和沖擊研磨作用。物料在破碎腔里受到巨大的擠壓力作用，當(dāng)擠壓力超過物料顆粒之間的內(nèi)聚力時(shí)，物料被破碎。沖擊式破碎是一種選擇性破碎，即沿物料的缺陷處破碎，不僅省功而且能保證粒度，減少過粉碎。在沖擊破碎開始瞬間，顆粒內(nèi)部產(chǎn)生應(yīng)力波，迅速向四方傳播，并在內(nèi)部缺陷、裂紋和晶粒界面等處產(chǎn)生應(yīng)力集中，促使顆粒首先沿這些脆弱面破碎。
B7100反擊式破碎機(jī)是基于沖擊破碎機(jī)理制造而成。原石料從機(jī)器頂部送入分料斗，借助控制門和分料擋板使原石料按一定比例通過料斗底部進(jìn)入高速運(yùn)轉(zhuǎn)的轉(zhuǎn)子或通過分料斗側(cè)面的分料口瀑布般落入破碎腔。原石料在轉(zhuǎn)子內(nèi)被加速到很高圓周速度，在離心力作用下通過轉(zhuǎn)子側(cè)面出口以50-85米/秒的速度向外飛出，與從分料口落下的石料顆粒發(fā)生非完全彈性碰撞，被擊碎的石料顆粒又與破碎腔中其他顆粒反復(fù)碰撞、磨碎，在腔內(nèi)形成紊流，越接近破碎腔內(nèi)壁，石料顆粒越小，速度越低，不久后失去能量的石料顆粒便落入成品料斗。期間，破碎腔內(nèi)壁附近始終有一層低速的小顆粒石料，這一層石料又為破碎腔提供一層石襯。這樣，破碎過程只是石料顆粒之間的相互作用，即“石-石磨碎反應(yīng)”，也稱為“石打石”破碎方式，因此反擊式破碎機(jī)又被稱為自生性碎石機(jī)。由于石料顆粒不直接與機(jī)體發(fā)生擠壓和摩擦，因而提高了碎石機(jī)的使用壽命。
3 反擊式破碎機(jī)的結(jié)構(gòu)特點(diǎn)
B7100型反擊式破碎機(jī)主要由破碎腔、料斗腔、分料器、轉(zhuǎn)子、傳動(dòng)系統(tǒng)、頂蓋、底座、電機(jī)等組成。與其他破碎機(jī)相比，該機(jī)在結(jié)構(gòu)上具有一些特點(diǎn)。
3.1 結(jié)構(gòu)獨(dú)特的破碎腔
破碎比是衡量破碎機(jī)破碎效果的一個(gè)重要指標(biāo)，B7100 型破碎機(jī)優(yōu)化的腔形設(shè)計(jì)提高了破碎比。提高破碎比意味著可減少破碎次數(shù)，節(jié)約設(shè)備用量投資。B7100 型反擊式破碎機(jī)對(duì)破碎腔腔形作了精心優(yōu)化設(shè)計(jì)，采用直線與曲線相結(jié)合，在破碎腔內(nèi)設(shè)有凸耳裝置，使得滯留物料有一安息角。從轉(zhuǎn)子中被加速的碎石在離心力作用下沿徑向運(yùn)動(dòng)，在破碎腔內(nèi)壁上形成一層由碎石組成的石襯。這層石襯也接受來自徑向高速運(yùn)動(dòng)的碎石的猛烈碰撞，這就是第二次“石打石”過程。同臺(tái)機(jī)器中的多次破碎使其破碎比高達(dá)12—15，而傳統(tǒng)破碎機(jī)的破碎比一般為3-6, B7100 型反擊式破碎機(jī)是實(shí)現(xiàn)“多破少磨”的理想設(shè)備。
3.2 精心設(shè)計(jì)的轉(zhuǎn)子
轉(zhuǎn)子開放式的結(jié)構(gòu)設(shè)計(jì)，能承受極硬物料如剛玉、石英等對(duì)轉(zhuǎn)子的多次沖擊和磨損。高耐磨性的襯板與轉(zhuǎn)子漿葉保證轉(zhuǎn)子能長(zhǎng)期使用，避免轉(zhuǎn)子反復(fù)拆裝。而且轉(zhuǎn)子上下板外側(cè)具有經(jīng)特殊耐磨材料制造的保護(hù)板，能完全避免轉(zhuǎn)子外端被磨損后引起轉(zhuǎn)子失效，消除因修復(fù)困難而造成經(jīng)濟(jì)損失。經(jīng)動(dòng)載平衡試驗(yàn)，轉(zhuǎn)子可以高速平穩(wěn)運(yùn)轉(zhuǎn)。
3.3 先進(jìn)的控制系統(tǒng)
B7100型破碎機(jī)的EMX控制柜可以實(shí)現(xiàn)恒電流軟啟動(dòng)和恒電流軟停機(jī)，可使電機(jī)起動(dòng)轉(zhuǎn)矩平滑增加，既避免大電流的沖擊損壞，又避免對(duì)電網(wǎng)的沖擊，同時(shí)具有過載、堵轉(zhuǎn)、欠壓、缺相等保護(hù)功能，不能滿負(fù)荷工作時(shí)，能提高電機(jī)功率因數(shù)和效率，節(jié)能效果顯著。
3.4 綠色環(huán)保型的設(shè)計(jì)
工作中振動(dòng)小、粉塵少，是一種環(huán)保型產(chǎn)品。B7100 型破碎機(jī)料斗中獨(dú)特的氣流轉(zhuǎn)換器能使氣流在機(jī)器內(nèi)循環(huán)，破碎機(jī)很少吸入空氣，因而較少有粉塵排出。這對(duì)改善石料廠的空氣質(zhì)量、保障操作人員的身體健康有著重要作用。
