E-breakers
The rapid development of the mining industry in recent years is only the beginning, mining equipment industry has been gradually driven. In the past, mining industry has not developed to a certain scale, concentrator, coal preparation plant and other industries generally used to broken equipment that small and medium-sized, and it is also slowly in recent years due to various sectors of production capacity to grow, such as production capacity has failed to keep pace with the needs of production, many manufacturers of large units and broken equipment, ore increasingly strong voice equipment . Gradually large jaw crusher (large E Breakers) has also emerged.
E-crushing machine called E-break, the series has broken than large, uniform product size, structure simple, reliable, easy maintenance, operating costs and economic characteristics. E-breaking machine (the jaw-breaking) widely used in mining, metallurgy, building materials, roads, railways, water conservancy and chemical industries, and many other departments, not broken compressive strength of more than 320 MPa of various materials.
In mine equipment, large jaw crusher, counter-crushing machine production capacity is obvious that such high energy consumption, high throughput of ore crusher are generally used in large-scale ore, coal preparation plant and other industries The broken, the current large 900 × 1200 broke the jaw of the large-scale break in Henan not be able to produce a few. The E-breakers is one of my company's flagship product, particularly in the design and production of large-scale E-breakers regardless of the technical process in terms of, or in terms of production capacity, both at home and abroad has been the absolute leader. The aircraft mainly used for all kinds of ores and medium-size bulk materials broken, broken compressive strength of not more than 320 Mpa materials, crude break points and broke two fine. The complete series of product specifications, the size of their feeding for 125 mm ~ 750mm, is the preferred initial broken equipment. E-breakers (E-breaking) widely used in mining, metallurgy, building materials, roads, railways, water conservancy and the industry, the scope of its application is very extensive,
E-breakers work, moving the jaw in the hoisting of the top direct eccentric axis, as a crank linkage of the link, from the eccentric shaft eccentric direct-drive, moving the bottom hinge of the jaw thrust plate attached to the rack of support after Wall. When the eccentric shaft rotation, moving the jaw on the movement of the points is hoisted from the point of the circle (equivalent to a radius of eccentricity), and gradually down into the Oval, the more downward Department, the oval-shaped side, until the bottom plate and thrust Connection point arc trajectory for the line. As a result of this mechanical activity in the jaw on the movement of the points is more complicated, the complex known as the swing-jaw crusher. Tilting the jaw-breakers and Jane tilting, compared to its advantages are: the quality of lighter, smaller components, the structure is more compact, broken cavity filled with good level, the blocks are homogeneous materials with broken jaw to move lower Introduced mandatory finished unloading, the higher productivity than with the specifications of the SR put Jaw Breakers 20-30 percent higher than the productivity; materials block in the lower part of a larger jaw moving up and down roller sports, the cube was easy Shape unloading, a decrease of as simple as tilting the sheet products in components, better product quality.
E-breakers of the main structure of a rack, the eccentric shaft, the pulley, flywheel and moving E, side-boards, panels elbow, elbow rear plate, screw-gap, reset spring, fixed-E and E-board activities such as group Cheng, also a board elbow insurance role. The Series E Breakers broken dynamic approach to music-compression, motor-driven belt and pulley, to move through the eccentric shaft from top to bottom E campaign, when moving up at the E-elbow angle between the E and dynamic change, thus promoting the move E-E board to be close, at the same time materials were squeezing, rubbing, grind, such as multiple broken when moving downstream Hubei Province, Hubei Province elbow dynamic between the board and smaller angle, moving in the E-drawbars, the role of spring From the E-board, at this time has broken materials from the crushing chamber from the mouth, as the motor for rotation broken motor E for cyclical pressure Broken and markers, and mass production.
Jaw Breakers of the crushing chamber is a fixed jaw jaw plate and activities of the board composition, and activities fixed jaw jaw is made of manganese steel liner has broken plates, broken plates fixed with bolts in the jaw board, in order to improve the crushing effect , The two have broken the surface of the plate with a corrugated vertical, and Tuao relative, so that the ore in addition to a crushing effect, there are bending and shear role.
Breakers of the work on both sides of the cavity wall is also equipped with manganese steel liner, because of the broken plate is uneven wear, the lower part of its larger and wear, to that end, often made of broken plates from top to bottom symmetrical to the bottom Wear, which will lead to its re-use, large-scale E-breakers from the broken board is a combination of many pieces, all can be interchangeable, which would extend the time limit for use of broken plates.
In order to make boards and broken jaw plate affixed a close, which must be lined by a liner made of plastic material, using zinc liner alloy of aluminum sheet or large plastic made because of paste will not close a big part too with , Is broken plates damaged, Setscrew pull off, or even cause the breakdown of the jaw move.
Activities of the jaw plate swing is to use the crank to achieve double-rocker mechanism, double-rocker mechanism by the crank shaft eccentric, connecting rod, the former thrust plate, and after the thrust board composition, eccentric shaft installed in the rack on the wall of the main Bearing in the linkage (first link) is installed in the eccentricity of the eccentric shaft, the thrust plate before and after the end of the next support on both sides of the first link in the groove of the elbow-seat, thrust before the board in support of the other side Lower jaw moving back wall of the elbow board seat, then thrust plate while the other end of the posterior support of the rack elbow board, when the eccentric shaft from the motor pulley through triangular access to power after the rotation, from top to bottom to make a link campaign, Linkage also led the movement from top to bottom thrust plate movement, the thrust plate to the changing angle, thereby moving the jaw swinging around the mandrel, the connecting rod upward movement when broken ore, when the link in the lower part of the minimum position, the thrust plate and the horizon By 10% of the tilt angle to 10 degrees Celsius or 12 degrees.
?E-breakers operating environment:
???? Will be broken in the huge stones into small stones in the process of the first crushing machine known as the "main" crusher. The longest history and also the strongest crusher is E-breakers. E-breakers to feed, the material from the top of the entrance into the broken tooth with E room. E-teeth with tremendous force will be material to the top wall, to be broken into smaller stones. E support the tooth movement is an eccentric shaft, the shaft runs through the fuselage frame. Usually fixed by the eccentric movement in the shaft at both ends of the flywheel by. Flywheel and eccentric bearings often used to support spherical roller bearings, the bearings of the working environment is extremely harsh. Bearing must be under tremendous impact load, abrasive sewage and high temperature. Although this work is extremely harsh environment, E-breakers need to work very reliable, which is to guarantee the production efficiency is a critical aspect.

顎式破碎機(jī)
礦山行業(yè)的飛速發(fā)展是在近幾年才開始的，礦山設(shè)備行業(yè)也逐漸被帶動(dòng)起來，以前在礦山行業(yè)還沒有發(fā)展到一定規(guī)模，選礦廠,選煤廠等行業(yè)一般用來破碎的設(shè)備都是中小型的，也是近幾年來也慢慢由于各個(gè)行業(yè)的生產(chǎn)能力逐漸增長(zhǎng)，這種成產(chǎn)能力已經(jīng)跟不上生產(chǎn)需要的，許多單位以及廠家對(duì)大型破碎設(shè)備，礦石設(shè)備的呼聲越來越強(qiáng)烈。逐漸大型顎式破碎機(jī)（大型顎式破碎機(jī)）也就應(yīng)運(yùn)而生了。
? 顎式破碎機(jī)簡(jiǎn)稱顎破，該系列產(chǎn)品具有破碎比大、產(chǎn)品粒度均勻、結(jié)構(gòu)簡(jiǎn)單、工作可靠、維修簡(jiǎn)便、運(yùn)營(yíng)費(fèi)用經(jīng)濟(jì)等特點(diǎn)。顎破機(jī)(顎破機(jī))廣泛運(yùn)用于礦山、冶煉、建材、公路、鐵路、水利和化學(xué)工業(yè)等眾多部門，破碎抗壓強(qiáng)度不超過320兆帕的各種物料。
在礦山設(shè)備中，大型的顎式破碎機(jī)，反擊式破碎機(jī)的生產(chǎn)能力是顯而易見的，這種高能耗，高礦石吞吐量的破碎機(jī)一般都用在大型礦石，選煤廠等行業(yè)的破碎，目前的大型顎破900×1200的大型破在河南沒有幾家能夠生產(chǎn)。該型顎式破碎機(jī)是我公司的主打產(chǎn)品之一，尤其在設(shè)計(jì)和生產(chǎn)大型顎式破碎機(jī)不論從技術(shù)工藝方面來講，還是從生產(chǎn)能力方面來講，在國(guó)內(nèi)外已處于絕對(duì)領(lǐng)先水平。該機(jī)主要用于各種礦石與大塊物料的中等粒度破碎，可破碎抗壓強(qiáng)度不大于320Mpa的物料，分粗破和細(xì)破兩種。該系列產(chǎn)品規(guī)格齊全，其給料粒度為125mm～750mm,是初級(jí)破碎首選設(shè)備。顎式破碎機(jī)(顎破)廣泛運(yùn)用于礦山、冶金、建材、公路、鐵路、水利和化等行業(yè)，它所應(yīng)用的范圍非常的廣泛，
顎式破碎機(jī)工作時(shí)候，動(dòng)顎上端直接懸掛在偏心軸上，作為曲柄連桿機(jī)構(gòu)的連桿，由偏心軸的偏心直接驅(qū)動(dòng)，動(dòng)顎的下端鉸連著推力板支撐到機(jī)架的后壁上。當(dāng)偏心軸旋轉(zhuǎn)時(shí)，動(dòng)顎上各點(diǎn)的運(yùn)動(dòng)軌跡是由懸掛點(diǎn)的圓周線(半徑等于偏心距)，逐漸向下變成橢圓形，越向下部，橢圓形越偏，直到下部與推力板連接點(diǎn)軌跡為圓弧線。由于這種機(jī)械中動(dòng)顎上各點(diǎn)的運(yùn)動(dòng)軌跡比較復(fù)雜，故稱為復(fù)雜擺動(dòng)式顎式破碎機(jī)。復(fù)擺式顎式破碎機(jī)與簡(jiǎn)擺式相比較，其優(yōu)點(diǎn)是：質(zhì)量較輕，構(gòu)件較少，結(jié)構(gòu)更緊湊，破碎腔內(nèi)充滿程度較好，所裝物料塊受到均勻破碎，加以動(dòng)顎下端強(qiáng)制性推出成品卸料，故生產(chǎn)率較高，比同規(guī)格的簡(jiǎn)擺顎式破碎機(jī)的生產(chǎn)率高出20-30%；物料塊在動(dòng)顎下部有較大的上下翻滾運(yùn)動(dòng)，容易呈立方體的形狀卸出，減少了像簡(jiǎn)擺式產(chǎn)品中那樣的片狀成分，產(chǎn)品質(zhì)量較好。
顎式破碎機(jī)的結(jié)構(gòu)主要有機(jī)架、偏心軸、大皮帶輪、飛輪、動(dòng)顎、側(cè)護(hù)板、肘板、肘板后座、調(diào)隙螺桿、復(fù)位彈簧、固定顎板與活動(dòng)顎板等組成，其中肘板還起到保險(xiǎn)作用。該系列顎式破碎機(jī)破碎方式為曲動(dòng)擠壓型，電動(dòng)機(jī)驅(qū)動(dòng)皮帶和皮帶輪，通過偏心軸使動(dòng)顎上下運(yùn)動(dòng)，當(dāng)動(dòng)顎上升時(shí)肘板和動(dòng)顎間夾角變大，從而推動(dòng)動(dòng)顎板向定顎板接近，與此同時(shí)物料被擠壓、搓、碾等多重破碎；當(dāng)動(dòng)顎下行時(shí)，肘板和動(dòng)顎間夾角變小，動(dòng)顎板在拉桿、彈簧的作用下離開定顎板，此時(shí)已破碎物料從破碎腔下口排出，隨著電動(dòng)機(jī)連續(xù)轉(zhuǎn)動(dòng)破碎機(jī)動(dòng)顎作周期性的壓碎和排料，實(shí)現(xiàn)批量生產(chǎn)。
顎式破碎機(jī)的破碎腔是有固定的顎板和活動(dòng)的顎板構(gòu)成，固定顎和活動(dòng)顎都襯有錳鋼制成的破碎板，破碎板用螺栓固定在顎板上，為了提高破碎效果，兩破碎板的表面都帶有縱向的波紋，而且凸凹相對(duì)，這樣，對(duì)礦石除有壓碎作用外，還有彎曲和剪切的作用。
破碎機(jī)的工作腔的兩側(cè)壁上也裝有錳鋼襯板，，由于破碎板的磨損是不均勻的，其下部磨損較大，為此，往往把破碎板制成上下對(duì)稱的，以便下部磨損后，將其導(dǎo)致而重復(fù)使用，大型顎式破碎機(jī)的破碎板是由許多塊兒組合而成，各個(gè)都可以互換的，這樣可以延長(zhǎng)破碎板的使用期限。
為了使破碎板與顎板緊密貼合，其間須襯有由可塑性材料制成的襯板，襯墊用鋅合金或塑性大的鋁板制成，因?yàn)橘N合不緊密會(huì)造成很大的局部過符合，是破碎板損壞，緊固螺栓拉斷，甚至還會(huì)造成動(dòng)顎的破裂。
活動(dòng)顎板的擺動(dòng)是借曲柄雙搖桿機(jī)構(gòu)來實(shí)現(xiàn)的，曲柄雙搖桿機(jī)構(gòu)由偏心軸，連桿，前推力板，和后推力板組成，偏心軸裝在機(jī)架側(cè)壁上的主軸承中，連桿（上連桿頭）則裝在偏心軸的偏心部分上，前后推力板的一端支撐在下連桿頭兩側(cè)凹槽中的肘板座上，前推力板的另一端支撐在動(dòng)顎后壁下端的肘板座上，而后推力板的另一端則支撐在機(jī)架后壁的肘板上，當(dāng)偏心軸通過三角皮帶輪從電動(dòng)機(jī)獲得旋轉(zhuǎn)動(dòng)力后，就使連桿產(chǎn)生上下運(yùn)動(dòng)，連桿的上下運(yùn)動(dòng)又帶動(dòng)推力板運(yùn)動(dòng)，由于推力板不斷改變傾斜角度，因而使動(dòng)顎繞心軸擺動(dòng)，連桿向上運(yùn)動(dòng)時(shí)進(jìn)行破碎礦石，當(dāng)連桿位于下部最低位置時(shí)候，推力板與水平線所成的傾斜角度為十度或十二度。
顎式破碎機(jī)運(yùn)行環(huán)境:?
????在將巨大石塊破碎成小石塊的過程中，第一道破碎機(jī)通常稱為“主”破碎機(jī)。歷史最長(zhǎng)，也最堅(jiān)固的破碎機(jī)是顎式破碎機(jī)。為顎式破碎機(jī)喂料時(shí)，物料從頂部入口倒入含有顎齒的破碎室。顎齒以巨大力量將物料頂向室壁，將之破碎成更小的石塊。支持顎齒運(yùn)動(dòng)的是一根偏心軸，此軸貫穿機(jī)身構(gòu)架。偏心運(yùn)動(dòng)通常由固定在軸兩端的飛輪所產(chǎn)生。飛輪和偏心支持軸承經(jīng)常采用球面滾子軸承，軸承的工作環(huán)境極為苛刻。軸承必須承受巨大的沖擊載荷，磨蝕性污水和高溫。盡管此工作環(huán)境極為苛刻，顎式破碎機(jī)仍需非常可靠地工作，這是保證生產(chǎn)效率的關(guān)鍵一環(huán)。
顎式破碎機(jī)性能特點(diǎn):
1.破碎腔深而且無死區(qū)，提高了進(jìn)料能力與產(chǎn)量；
2.其破碎比大，產(chǎn)品粒度均勻；

5.結(jié)構(gòu)簡(jiǎn)單，工作可靠，運(yùn)營(yíng)費(fèi)用低。
6.設(shè)備節(jié)能：?jiǎn)螜C(jī)節(jié)能15%～30%，系統(tǒng)節(jié)能一倍以上；
7.排料口調(diào)整范圍大，可滿足不同用戶的要求；
8.噪音低，粉塵少
