1E-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 2production 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 3of 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 4plate 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, 5when 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; 65. 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 7the 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 8work and increase the voltage, so as to re-host Contains requirements 6) the replacement of bearings or moving the jaw.
