E-breakersThe 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 companys 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. E-breakers performance characteristics: 1. Crushing chamber deep and no dead zone, improve the capacity and output of raw materials; 2. Crushing than their large, uniform size products; 3. Pads nesting population adjustment devices, convenient and reliable, the scope of regulation, increase the flexibility of the equipment; 4. Lubrication system is safe and reliable, convenient replacement parts, maintenance workload small;5. Structure is simple, reliable, low-cost carriers. 6. Energy-saving equipment: stand-alone energy-saving 15 percent to 30 percent, more than double the energy system; 7. Nesting population adjustment range, can meet the requirements of different users; 8. Low noise, dust less E-breakers use and the use of: 1.the Series E Breakers (E-breaking) mainly used for metallurgical, mining, chemical, cement, construction, ceramics and refractories, such as for the industrial sector in Grinding and broken all kinds of minerals in hard rock and use. 2. the series of jaw breakers (broken jaw) the most appropriate broken compressive strength of not more than 300 MPa (MPa) of hard and soft ore, was broken material may not be larger than the largest block of technical parameters under the table . Large breakers of the installation process relatively trouble, the need for lifting machinery, aircraft in trial operation, should pay attention to double-check circuit and the distribution cabinet. Prevent accidents. Large breakers in the production process, should pay attention to maintaining a timely manner, the abnormal phenomenon should immediately stands check to see which parts of the machine failure, it should be timely maintenance. To ensure the normal operation of machinery. Jaw Breakers troubleshooting Occurrence 1: Host sudden shutdown (commonly known as: nausea vehicles). Reasons: 1) plug the nesting population, resulting in wholehearted blocking materials; 2) rotation of the drive shafts round of the 1.30-belt, the belt slipping 3) bear the eccentric shaft sleeve loose, causing the rack no bearing on both sides of the Gap, the eccentric shaft stick, not rotation; 4) at work and low voltage, host encountered Daliao, the inability broken; 5) bearing damage. Exclude: 1) I plug the removal of nesting, to ensure smooth flow of materials, 2)-tight belt or replacement of 1.30, 3) re-install or replace bear the hub, 4) are at work and for the voltage, so that it operates in line with the mainframe Requirements, 5) the replacement of bearings. Occurrence 2: Host tank round, moving the jaw in normal operation, but the broken stop work. Reasons: 1) tension spring fault; 2) drawbars fault; 3) loss or plate elbow fracture. Exclude: 1) the replacement of tension spring; 2) the replacement of drawbars 3) re-install or replace the elbow plate. Occurrence 3: output of less than factory standards. Reasons: 1) the hardness or broken materials toughness over the provisions of the Manual, 2) electrical wiring to the anti-location, a host anti-car (a jaw clockwise rotation), or motor triangle to law to access law into astrocytes 3) provides nesting population is less than the limit, 4) shift the jaw plate, top teeth and tooth relatively Top 5) low-voltage work at the scene; 6) moving the jaw and bearing wear after the gap is too large, so that bearing in outer ring Relative rotation. Exclude: 1) to replace or increase the crusher, 2) the electrical wiring swapped 3) nesting population was adjusted to the provisions of the said statement nesting mouth and Grinding increase for the Breakers, 4) check from the tooth-tooth size, such as To be sub-standard replacement jaw plates, is fixed for the jaw-jaw plate with the activities of the relative position to ensure that addendum to the tooth root, fixed pinched to prevent displacement; 5) at work and increase the voltage, so as to re-host Contains requirements 6) the replacement of bearings or moving the jaw.顎式破碎機礦山行業(yè)的飛速發(fā)展是在近幾年才開始的,礦山設備行業(yè)也逐漸被帶動起來,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)一般用來破碎的設備都是中小型的,也是近幾年來也慢慢由于各個行業(yè)的生產能力逐漸增長,這種成產能力已經跟不上生產需要的,許多單位以及廠家對大型破碎設備,礦石設備的呼聲越來越強烈。逐漸大型顎式破碎機(大型顎式破碎機)也就應運而生了。 顎式破碎機簡稱顎破,該系列產品具有破碎比大、產品粒度均勻、結構簡單、工作可靠、維修簡便、運營費用經濟等特點。顎破機(顎破機)廣泛運用于礦山、冶煉、建材、公路、鐵路、水利和化學工業(yè)等眾多部門,破碎抗壓強度不超過320兆帕的各種物料。 在礦山設備中,大型的顎式破碎機,反擊式破碎機的生產能力是顯而易見的,這種高能耗,高礦石吞吐量的破碎機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9001200的大型破在河南沒有幾家能夠生產。該型顎式破碎機是我公司的主打產品之一,尤其在設計和生產大型顎式破碎機不論從技術工藝方面來講,還是從生產能力方面來講,在國內外已處于絕對領先水平。該機主要用于各種礦石與大塊物料的中等粒度破碎,可破碎抗壓強度不大于320Mpa的物料,分粗破和細破兩種。該系列產品規(guī)格齊全,其給料粒度為125mm750mm,是初級破碎首選設備。顎式破碎機(顎破)廣泛運用于礦山、冶金、建材、公路、鐵路、水利和化等行業(yè),它所應用的范圍非常的廣泛, 顎式破碎機工作時候,動顎上端直接懸掛在偏心軸上,作為曲柄連桿機構的連桿,由偏心軸的偏心直接驅動,動顎的下端鉸連著推力板支撐到機架的后壁上。當偏心軸旋轉時,動顎上各點的運動軌跡是由懸掛點的圓周線(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軌跡為圓弧線。由于這種機械中動顎上各點的運動軌跡比較復雜,故稱為復雜擺動式顎式破碎機。復擺式顎式破碎機與簡擺式相比較,其優(yōu)點是:質量較輕,構件較少,結構更緊湊,破碎腔內充滿程度較好,所裝物料塊受到均勻破碎,加以動顎下端強制性推出成品卸料,故生產率較高,比同規(guī)格的簡擺顎式破碎機的生產率高出20-30%;物料塊在動顎下部有較大的上下翻滾運動,容易呈立方體的形狀卸出,減少了像簡擺式產品中那樣的片狀成分,產品質量較好。顎式破碎機的結構主要有機架、偏心軸、大皮帶輪、飛輪、動顎、側護板、肘板、肘板后座、調隙螺桿、復位彈簧、固定顎板與活動顎板等組成,其中肘板還起到保險作用。該系列顎式破碎機破碎方式為曲動擠壓型,電動機驅動皮帶和皮帶輪,通過偏心軸使動顎上下運動,當動顎上升時肘板和動顎間夾角變大,從而推動動顎板向定顎板接近,與此同時物料被擠壓、搓、碾等多重破碎;當動顎下行時,肘板和動顎間夾角變小,動顎板在拉桿、彈簧的作用下離開定顎板,此時已破碎物料從破碎腔下口排出,隨著電動機連續(xù)轉動破碎機動顎作周期性的壓碎和排料,實現(xiàn)批量生產。顎式破碎機的破碎腔是有固定的顎板和活動的顎板構成,固定顎和活動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,這樣,對礦石除有壓碎作用外,還有彎曲和剪切的作用。破碎機的工作腔的兩側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稱的,以便下部磨損后,將其導致而重復使用,大型顎式破碎機的破碎板是由許多塊兒組合而成,各個都可以互換的,這樣可以延長破碎板的使用期限。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,因為貼合不緊密會造成很大的局部過符合,是破碎板損壞,緊固螺栓拉斷,甚至還會造成動顎的破裂。活動顎板的擺動是借曲柄雙搖桿機構來實現(xiàn)的,曲柄雙搖桿機構由偏心軸,連桿,前推力板,和后推力板組成,偏心軸裝在機架側壁上的主軸承中,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凹槽中的肘板座上,前推力板的另一端支撐在動顎后壁下端的肘板座上,而后推力板的另一端則支撐在機架后壁的肘板上,當偏心軸通過三角皮帶輪從電動機獲得旋轉動力后,就使連桿產生上下運動,連桿的上下運動又帶動推力板運動,由于推力板不斷改變傾斜角度,因而使動顎繞心軸擺動,連桿向上運動時進行破碎礦石,當連桿位于下部最低位置時候,推力板與水平線所成的傾斜角度為十度或十二度。顎式破碎機運行環(huán)境:在將巨大石塊破碎成小石塊的過程中,第一道破碎機通常稱為“主”破碎機。歷史最長,也最堅固的破碎機是顎式破碎機。為顎式破碎機喂料時,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。支持顎齒運動的是一根偏心軸,此軸貫穿機身構架。偏心運動通常由固定在軸兩端的飛輪所產生。飛輪和偏心支持軸承經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,顎式破碎機仍需非??煽康毓ぷ鳎@是保證生產效率的關鍵一環(huán)。顎式破碎機性能特點:1.破碎腔深而且無死區(qū),提高了進料能力與產量;2.其破碎比大,產品粒度均勻;3.墊片式排料口調整裝置,可靠方便,調節(jié)范圍大,增加了設備的靈活性;4.潤滑系統(tǒng)安全可靠,部件更換方便,保養(yǎng)工作量??;5.結構簡單,工作可靠,運營費用低。6.設備節(jié)能:單機節(jié)能15%30%,系統(tǒng)節(jié)能一倍以上;7.排料口調整范圍大,可滿足不同用戶的要求;8.噪音低,粉塵少顎式破碎機用途和使用范圍:1、該系列顎式破碎機(顎破)主要用于冶金、礦山、化工、水泥、建筑、耐火材料及陶瓷等工業(yè)部門作中碎和細碎各種中硬礦石和巖石用。 2、該系列顎式破碎機(顎破)最適宜于破碎抗壓強度不高于300MPa(兆帕)的各種軟硬礦石,被破碎物料的最大塊度不得大于技術參數表所規(guī)定。大型破碎機的的安裝過程比較的麻煩,需要機器的吊裝,在試運行該機時候,應注意仔細檢查電路以及配電柜。以防出現(xiàn)意外。大型破碎機在生產過程中,應及時注意維護,對出現(xiàn)的異?,F(xiàn)象應立即停機進行檢查,看是機器的那個部位出現(xiàn)故障,應該及時檢修。確保機器的正常運轉。 顎式破碎機故障排除故障現(xiàn)象1:主機突然停機(俗稱:悶車)。原因:1)排料口堵塞,造成滿腔堵料;2)驅動槽輪轉動的三角皮帶過松,造成皮帶打滑;3)偏心軸緊定襯套松動,造成機架的軸承座內兩邊無間隙,使偏心軸卡死,無法轉動;4)工作場地電壓過低,主機遇到大料后,無力破碎;5)軸承損壞。排除方法:1)清除排料口堵塞物,確保出料暢通;2)調緊或更換三角皮帶;3)重新安裝或更換緊定襯套;4)調正工作場地的電壓,使之符合主機工作電壓的要求;5)更換軸承。 故障現(xiàn)象2:主機槽輪、動顎運轉正常,但破碎工作停止。原因:1)拉緊彈簧斷裂;2)拉桿斷裂;3)肘板脫落或斷裂。排除方法:1)更換拉緊彈簧;2)更換拉桿;3)重新安裝或更換肘板。故障現(xiàn)象3:產量達不到出廠標準。原因:1)被破碎物料的硬度或韌性超過使用說明書規(guī)定的范圍;2)電動機接線位置接反,主機開反車(動顎順時針旋轉),或電機三角形接法接成星形接法;3)排料口小于規(guī)定極限;4)顎板移位,齒頂與齒頂相對;5)工作現(xiàn)場電壓過低;6)動顎與軸承磨損后間隙過大,使軸承外圈發(fā)生相對轉動。排除方法:1)更換或增加破碎機;2)調換電機接線;3)排料口調整到說明書規(guī)定的公稱排料口和增加用于細碎的破碎機;4)檢查齒板齒距尺寸,如不符標準則須更換顎板,調正固定顎板與活動顎板的相對位置,保證齒頂對齒根后,固定壓緊,防止移位;5)調高工作場地電壓,使之適應主機重載要求;6)更換軸承或動顎。12
