Stone Jaw Crusher the efficient production of high quality sand and gravel is directly linked to selection and economic benefit

Lithotripsy is a commonly used device in the ore crushing process gravel equipment technology and performance has been improved, and launched a lot of broken stone equipment, technology and performance of these devices are more perfect, outstanding results in the ore processing, by people of all ages.

Although there are many kinds of breaker equipment, but e-hammer in mining and construction industries to use lots of broken equipment, is also a popular performance advantages of a very prominent broken machines. Different breaker corresponding to the different functions, but the goal is to break ore. It takes the user through their own understanding and demand, again according to the geography of the site were chosen for their equipment. In mineral processing and smelting stone must now be broken. Jaw Crusher is relatively common, and using a broad range of devices, then to analyze the way its broken, so that the majority of users know more about e-hammer for this device.

Jaw Crusher is broken as broken liner ore split, and split broken ore is crushed between two broken liner. In the jaw in a complex process of shaking, outside the broken ore in addition to splitting and crushing and grinding. How Jaw Crusher works to make stone crusher is more thorough and more uniform product grain shape, the same size, a cube; high efficiency and energy saving.
Breaker selection and is directly linked to economic benefits

Crusher is mainly used for stone crushing and processing equipment, is an indispensable part of the ore mining and processing. Crusher applied as a crushing, ore dressing, metallurgy, electric power and other industrial equipment for mechanical applications, Hammer’s role is in doubt. As the industry continues to progress and improvement, a wide variety of hammer on the market today, hammer models are very well equipped, the choice of people in the rubble, should also pay special attention, according to the nature of the materials, select the appropriate type of lithotripsy equipment.
If to select now market Shang of gravel machine words, we important to see of place is gravel machine it of lining Board, it is the equipment in the bear load of key parts, the lining Board it of performance and using life on directly relationship with we to select of gravel machine of using life, in addition lining Board of hosted load also decided with the equipment of efficiency and general user of production cost,. So we had better select which load of gravel. Lithotripsy machine options at the same time, must pay attention to choose the regular factory equipment, such equipment can guarantee the quality.

To ensure the safe operation of the equipment, of course, not only to choose a good device, should also pay attention to in the use, correct operation as and when required, and in equipment maintenance and repair work, equipment maintenance work on a regular basis, so as to improve the efficiency of equipment, extend life expectancy, reducing production costs.


Mining Crusher development

Crusher is reliable, durable and at the same time merged with energy saving features, users can rest assured that use. Following our main introduce Crusher this course of development, since the ancient times, so that our customer understanding of history has a system for lithotripsy.

Crusher means discharging contents of grain size larger than three millimeters in 50% above the total discharge amount of milling machinery. Shredder feeding and discharging grain size, broken into coarse, medium and fine crushing. Commonly used aggregate equipment are Jaw Crusher, impact crusher, impact crusher, combination crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, roller crusher double roll crushers, combo breakers, a molding machine, and so on.
Is the use of both jaw plates of Jaw Crusher material compression and bending, rough or broken in pieces of hard material Crusher. Its crushing by the stationary jaw and movable jaw plates, was broken when two jaw plate close to the material, when the two jaw left less than material at the bottom of the nesting population discharge. Its crushing action is intermittent. The crusher because of simple structure, reliable operation and the advantages of hard materials can be broken and is widely used in mineral processing, building materials, silicate and ceramic industries.

The 40 century 80 ‘s, 800 tons of materials per hour broken large Jaw Crusher feeding granularity up to about 1800 mm. Jaw Crusher double toggle and single bracket two. Former jaw only briefly when he works swing arc, it is also called a simple oscillating Jaw Crusher which in swing arc as well as up and down motion, so it is also called complex swing Jaw Crusher. Jaw Crusher is widely used in mining, metallurgy, building material, highway, railway, water conservancy, chemical industry and other departments, no more than 320 MPA compressive strength of various materials.

Jaw Crusher jaw up and down movement promoting the role of discharge, and the upper horizontal stroke is greater than the lower, easy to break large materials, so its efficiency is higher than two-bracket system. Its disadvantage is that jaw plate wears out quickly, as well as the material could have been crushed and increased energy consumption.   In order to protect the important parts of the machine are not damaged due to overload, often simple shapes, small bracket designed for weak links, making it first when the overload of the machine deformation or fracture. In addition, different discharging granularity to meet demand and compensate for wear of the jaw, and addition of discharge opening adjustment, usually in brackets and add adjustment shims or wedges between the rear frame rail. But in order to avoid the replacement of the parts breakdown affecting the production, or hydraulic device to achieve the safety and adjustment. Jaw Crusher directly driven with hydraulic drive, swing jaw, to the breaking of the item is complete. The two types of hydraulic actuator Jaw Crusher, often referred to as hydraulic Jaw Crusher.


Introduction to the crusher and Crusher working principle

Crusher with large reduction ratio, high yield product granularity, simple structure, after more than 20 years of development and evolution from the first generation of vertical shaft crusher, the fifth generation from a single attack, turned into anti-broken, a hammer effect than the old model, improve the lives of 4 times. The ore assigned by the feed port, through falling into the machine, distribution panel at the upper end of the vertical axis, due to the vertical axis of rotation, and vibration, evenly distribute ores in the cone for four weeks. With attached handle of hinges and hinge, the fixed cone rises or falls, in order to regulate the width of discharge opening. In fact, the so-called hammer is a hammer stone crushing process.

With the development of mining industry, stone machine industry continues to move forward, inter-firm competition harder and harder, and hammer prices also had an impact, but in any case, hammer investment plays an important role in the production and construction, and renders the increasing trend. One in purpose and meaning, as well as costs, tentatively in mineral processing of metallurgical industry, for example, material crushing jobs play an important role. Cost of concentrator crushing and grinding operations, accounted for all of the ore dressing production line processes an average production cost of more than 40%, while rubble investments accounted for ore-dressing plant with a total investment of more than 60%. We could see very clearly, broken equipment in the entire process of the important position and the proportion of costs. In the cement industry in the crushing and grinding of cement plant operating costs more than 30% per cent of the production cost, broken machinery and electricity consumption of about 10% of plant total electricity consumption, electricity consumption to 60% of grinding machines.

Crusher working principle
Stone from the top of machine directly into high-speed rotating turntable; in high speed under the action of centrifugal force, and another part of umbrella fly stone shunting with the way around the turntable high speed impact and high density crush, after stone against each other, and rotary table and chassis form Vortex motion between several times to punch each other, grinding, crushing, discharge directly from the bottom. Form a closed loop multiple times, controlled by the screening equipment reached the desired size.

For example, such as vertical Crusher representative products of vertical shaft impact crusher, is widely used in iron ore, gold, cement, glass, ceramic, electric power, iron and steel industry material crushing. However, if you select a vertical Crusher crushing for road construction material, that is the selection error. Lithotripsy lithotripsy is flexible. Regardless of the hard limestone, basalt, or different sizes of stone production of ore crushing, it can play 1, fine, Super Smash a variety of operations, which is unparalleled in other Crusher. And productivity is several times, General crusher is also determined by its average particle breakage was very evenly. Than finished pieces of broken machines on the market is much better. In addition to the tensile strength of the material may adjust the size of the machine. Therefore, in order to further expand the scope of its application. I think it will gradually replace the ordinary spring cone Crusher.

Hammer use
Crusher application: according to reports, about 15% in the world of electric energy consumption during grinding operations, and increased year by year, which more than 85% used for grinding. With the increase in ore and building materials demand constantly increasing, industrial-use proportion of recycled materials have accumulated more and more, coupled with energy shortages, need continuous improvement of grinding operation, such as the use of “more crushing and less grinding” process, especially developed high performance grinding equipment and improving the existing grinding machine, to achieve high quality, high yield, low cost, low energy consumption is of great significance.

Jaw Crusher working principle

Jaw Crusher has a variety of structural forms, work on the same principle, that is crushing material through the cyclical movements of the jaw. Swing to the fixed jaw jaw hanging around the mandrel in the process, the material located between the two jaw plate could be crushing, splitting, bending, and comprehensive. At the start, less pressure, volume of materials, materials are close to each other and jam between; when the pressure rises to more than material can withstand the strength, is broken. Otherwise, when the jaw when you leave the fixed jaw to swing in the opposite direction, fall by gravity downward movement of material. Jaw once every periodic movement of material to be crushed, and the carriage some distance down. After several cycles, the materials were broken from the discharge opening discharge machines. Mobile jaw broken with the continuous rotation of the motor cycle sport crush and discharge materials and mass production.


Rock Crusher details

Technology type of Rock Crusher

1, under the crushing force of Crusher can be roughly divided into two broad categories:

(1) the crusher (2) grinding machine
Crusher working with large blocks of material, coarse particle size, typically greater than 8 mm. A certain gap between its structure is broken, do not touch each other. Crusher can be divided into coarse crushing machine, crusher and Crusher. In general the material processed by the mill is fine, product size is fine, up to 0. 074 mm, even thinner. Its structure is broken parts (or medium) touch each other, the medium used is steel ball, steel, gravel, or mineral block and other. But some machinery was both crushing and grinding, such as mill. L 5. 5×1. 8 m since the mills processing ore size limit up to 350~400 mm

2, depending on how broken, mechanical structural features (principles) divided broadly into six categories
(1) Jaw Crusher (Tiger). Breaking action depends on the moveable jaw plate pressed against the fixed jaw plate periodically, to clip in one of ore crushing
(2) cone Crusher. Nugget in between the inner and outer cone, fixed outer cone, cone eccentric wobble, in between blocks of ore, crushed or broken
(3) the roll Crusher. Nuggets in two opposite rotation between the round roll, mainly by the continuous crushing action, but also with a grinding role, splitting breaking role for tooth surface

(4) impact crusher. Nugget of fast rotating moving part being crushed by the impact. Fall into this category can be further divided into: Hammer mill; cage Crusher; impact crusher
(5) the grinding machine. Ore in a rotating cylindrical grinding media (steel ball, steel bars, gravel, or mineral block) being crushed by the impact and abrasive.
A, roll grinding machine: take the turning rollers to crush items.
B, plate mill: using vertical or horizontal axis of the disc as a broken part.

C, centrifugal grinding machine. The high-speed rotating centrifugal force to complete the broken parts and media production.
D, vibration grinding machine. Axis high frequency vibrations, which makes the media and completed items are hitting each other and breaking.
Various types of crushers has different specifications, different use. Coarse crushing by Jaw Crusher cone Crusher or cycles; broken in standard cone Crusher fine short head type cone Crusher.


Rock Crusher describes the purpose and classification and performance

The introduction of lithotripter

Lithotripsy machine in accordance with the categories can be divided into medical gravel and mining hammer. Mining hammer principle adapted to the massive hard rock mines, the typical granite leaves the material granularity 40mm 90%, the function 100~500 mm on a side item, the compressive strength of up to 350 MPA, with high crushing ratio, after breaking a cube of material particles and so on. Mining Crusher machine is discharging contents of grain size larger than three millimeters in 50% above the total discharge amount of milling machinery.

Crusher according to the categories can be divided into medical crusher and mining Crusher. Medical stone is used for stone crushing and resonance are commonly used, such as stone breaking, avoid the risk of surgery.
According to the principle of breaking, heavy mining machinery Crusher Jaw Crusher, impact crusher, vertical impact crusher, cone crusher, hammer crusher, hammer crusher, roller crusher, combination crusher, cone crusher, two-stage crusher, gyratory crusher, mobile crusher, etc.
Different types of Crusher working principle is completely different, with ring hammer crusher, for example:
Hammer crusher is mainly broken material impact energy to the job. Hammer type broken machine work Shi, motor led rotor for high-speed rotating, material uniform of into broken machine cavity in the, high-speed rotary of hammer impact, and shear tear material to material was broken, while, material itself of gravity role makes material from high-speed rotating of hammer rushed to frame body bezel, and screen article, in rotor lower, has screen Board, and crushed material in the is less than screen hole size of grain level through screen Board discharge, is greater than screen hole size of material resistance left in screen Board Shang continues to by hammer of combat and grinding.
Performance and usage

Impact crusher appeared relatively late, but very fast. It has been China’s cement, building materials, coal, chemical and mineral processing industries are widely used in various ores, minor operations. it is also used as a coarse ore equipment. Inversed impact crusher is so rapidly largely because it has the following important features.
Uniform product size. crush problems. This fragmentation. Is the use of kinetic energy of crushing ore, and the kinetic energy of the rock and the rock mass, proportional. … In the process of crushing, lump ore is largely broken. but small particles of ore, under certain conditions, not to be broken. uniform product size.


Broken Rock Crusher type

Jaw Crusher appeared in 1858. Although it is one of the oldest pieces of equipment, but due to the simple structure, reliable performance, easy to manufacture, easy maintenance, and other advantages, so still in the metallurgical and mining, building materials, chemical industry and railway sectors get widely. In metal mines, which are mostly used for hard or medium hard ores are coarsely chopped and shredded. Jaw Crusher is usually follow the moveable jaw plate (e) motion to classify, most widely used in the industry has two main types:

1, briefly swinging jaw double toggle mechanism (the so-called simple pendulum) of Jaw Crusher.

2, complex swing jaw single toggle mechanism (called a compound pendulum) of Jaw Crusher. Hydraulic technology applied in crushing equipment, hydraulic Jaw Crusher appeared.
(1) simple pendulum Jaw Crusher-(2)-a compound pendulum Jaw Crusher (3)-hydraulic Jaw Crusher.
Moveable jaw plate is moving with connecting rod, thrust plate bodies to achieve. It was by flywheel 7, 8 eccentric shaft, connecting rods 9, former thrust and thrust plate 13. When through the pulley of the motor drives eccentric shaft rotates, the connecting rod motion. Connecting rod moves up and down, driving thrust plate movement. As a result of movements are constantly changing the tilt angle of the thrust plate, and the moveable jaw plate around suspension shafts for reciprocating motion, thus crushing ore. When move jaw forward swing, horizontal lever spring gets balanced jaw and the inertial forces of the thrust plate, jaw thrust plate and combination will not be separated. When the jaw back, spring assist role to play.
Flywheel because of Jaw Crusher is stopped working, working and idle stroke, so it did not balance the load on the motor. For the load evenly, would occur in the jaw is moved backward (away from the fixed jaw plate), the energy stored up idle stroke in order to work trips (for crushing ore), the energy is released again. Using the principle of inertia, on both ends of the eccentric shaft and installation of a flywheel can achieve this objective. In order to simplify the structure of machine, usually for transmitting power using one of the flywheels and pulleys. For two motor-driven major Jaw Crusher, two flywheel pulley, pulley and take off wheel.

Eccentric shaft or spindle crusher is an important part of it is, simple pendulum Jaw Crusher jaw suspension shafts and spindles. Eccentric shaft is driven up and down movement of the connecting rod main parts, due to the large crushing force on their work, and are generally made of high quality steel production. According to China resources, large Jaw Crusher of the eccentric shaft using manganese-molybdenum-vanadium, boron and manganese-molybdenum-chromium-molybdenum alloy steel is appropriate. Small Jaw Crusher is manufactured using the 45th steel. Eccentric shaft should be quenched and tempered or normalized heat treatment to improve the strength and wear resistance. Steel spindle general use of 45th.
Link only the simple pendulum Jaw Crusher has, it is composed by the connecting rod and crank end. Due to work under tension, it made with steel. There is overall and combinations of the two connecting rods, which for many medium and small Jaw Crusher, which is mainly used for large Jaw Crusher. In order to reduce the inertia effect of the connecting rod, should seek to reduce the weight of connecting rods, so, small Jaw Crusher used in “work” or “ten”-shaped cross section structure and large Jaw Crusher used box-section form. Hydraulic Jaw Crusher, Rod body is also equipped with a hydraulic cylinder (plunger), insurance role in when the machine is overloaded.
Adjustment device it was Crusher discharge size adjustment mechanism. With the broken tooth plate wear, increase discharge opening, broken grain becomes thicker. In order to guarantee the product size requirements, you must use equipment, periodic adjustment of the discharge opening size.
Jaw Crusher discharge opening adjustment method, there are three main forms:
1 and shim adjustment. In the thrust bearing between the posterior wall of the rack and into a group of equal thickness of gasket. Use to increase or reduce the number of spacer layer, making Crusher discharge opening decreases or increases. This approach can be multiple adjustments, machine structure compact, you can reduce the weight of equipment, but must pay parking. Large Jaw Crusher used this method of adjustment.

2, wedge adjustments. With thrust bearing between the posterior wall of the rack and the two realized the wedges relative Crusher discharge opening adjustment. Turn the nut on the bolt and adjustment wedges along the back wall of the rack up or down move, drives wedges before “moving forward or backward, so as to promote or jaw thrust plate, for the purpose of discharge opening adjustment. This method can achieve the stepless adjustment, easy to adjust, to save time, do not stop adjustment, but increasing the size and weight of the machine. Medium and small Jaw Crusher often use the adjusting device.
3, hydraulic adjustment: 2012 years where there is installed to adjust the discharge opening of the hydraulic cylinder, Jaw Crusher hydraulic safety device, which is reliable and secure, and easy to troubleshoot. The crusher is equipped with a hydraulic cylinder and piston on the connecting rod, cylinder connected with the upper part of the connecting rod, piston and bearing thrust plate convergence. Normal working hours, with pressure in the fuel tank of oil, the piston rod and cylinder is equivalent to a whole. When entering the crushing Chamber the broken objects, connecting rod stress increases rapidly, the oil pressure suddenly increased in the fuel tank, opened the valve for fluid flow, being squeezed out of the pressure oil, the piston and the cylinder release. At this point, connecting rod cylinder while still moving up and down with the rotation of the eccentric shaft, connecting rod-piston fixed, so the thrust plate and moving jaw does not swing, play the role of safety device. With the development of hydraulic technology, this Crusher will be widely used.
Worth noting is that head of the connecting rod bolt or PIN on the flywheel (keys), as Jaw Crusher safety device is not appropriate. Jaw Crusher jaw broken for short, the series has broken than large, equal product granularity, simple structure, reliable operation, easy maintenance, low operation cost and so on. Jaw Crusher (broken jaw) is widely used in mining, metallurgical, building material, highway, railway, water conservancy, chemical industry and other departments, no more than 320 MPA compressive strength of various materials.
