Overview of Jaw Crusher

Jaw crusher is mainly used in all kinds of ores and medium size large materials, can be broken the compressive strength is not more than 320Mpa materials, coarse and fine broken break point two. This series of jaw broken the product specification is complete, the feeding for125mm~750mmsize, is the primary crushing the preferred equipment.

XSM jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. The pressure resistance strength is under 320Mpa, suitable for primary crush.Jaw Crusher can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.

Major Types of Jaw Crusher

In the mining industry, jaw crusher is one of the most widely used rock crushers. According to the crushing stage of this crusher, it can be divided into primary jaw crusher and secondary jaw crusher; according to the number of the toggles, it can be divided into single toggle jaw crusher and multiple toggle jaw crusher.

There are many types of jaw crushers, such as mobile jaw crusher, aggregate jaw crusher, mini single toggle jaw crusher, etc. Every feature of these machines has been carefully designed to provide superior quality and performance. They are widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys, etc. These crushers are recommended by leading consultants in this field and are used by customers all over the world.

Working Principle of Jaw Crusher

The crushing style of jaw crusher is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising, the included angle between the wrist plate and movable jaw becomes bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing.

When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.

Jaw Crusher Main Features and Advantages:

1. Crushing cavity is deep without dead zone. It is easier to feed materials and yield higher output.2. Jaw crusher is featured with high crushing ratio and sound epigranularity.3. The gasket type adjusting device of the discharge gate is characterized by reliable performance, convenient use, large adjusting range, and improves the equipment flexibility.4. The lubricating system is safe and reliable. It makes it easier to replace components and requires little maintenance.5. Jaw crusher features simple structure, reliable performance and low operating cost.6. It is highly energy saving. A single machine saves 15%~30% of energy consumed and the system can save over half the energy consumed.7. To meet different client needs, the discharge gate is designed with a large adjusting range.8. Jaw crusher causes low noise and creates little dust.

Jaw crusher structure and design

XSM stone jaw crushers are premium class crushers due to their design as well as to the materials that are used to produce them, so as to ensure the highest possible functionality and reliability, without any compromises. Each model is tested virtually for stress, strain, shock, deformation, thermal loading, vibration and noise under a wide range of load conditions. The result is exceptional reliability.

The Right Cavity DesignHow to improve the capacity? The cavity is the heart and only purpose of the stone jaw crushers. The right feed opening width to depth ratio ensures minimum blockage and eliminates unnecessary height from the crusher. The tooth profiles as well as the thickness of the jaws are optimized and combined with the right manganese steel alloys to maximize throughput and minimize operating costs.

Little Dust and Low Noise LevelsEquipped with dust-cleaning apparatus water tank, in order to reduce the noise, damping layer is filled in the interlayer between the upper body and the lower body. All these combines to create a safer and cleaner working environment.

Components of a Jaw Crusher

1. Jaw plate and side guard plate

Jaw Plates are one of the most important parts of jaw crusher. It is between two jaw plates (fixed and swing) that the crushing takes place. Since it’s the part that takes most of the beating, it’s the one that needs most frequent replacement.If you are in an industry that uses them, then you no doubt understand the important nature of jaw crushers, and of the jaw plates that are used with them. It’s very important that an eye be kept on the plates to ensure that they last for the longest amount of time possible.

2. Flywheel

Flywheel of jaw crusher is used for storage the energy when movable jaw crusher is idling, which and then is used for making a uniform working. The belt wheel also has the function of flywheel. Often the flywheel is casted of iron or steel with the small jaw crusher of unitary casting. Balance of flywheel should be paid attention to in installation.3. Adjustment device

Adjustment device has wedge adjustment, subplate adjustment and hydraulic adjustment with common adjustment of wedge, which includes two wedges in front and in back of crusher. The front wedge can move from the front to the back with the function of holding against the back driving plate. However, the back wedge belongs to the adjusting wedge with moving from up to bottom. The two wedges joint by reverse direction and adjust the discharging hole by fluctuation under the force of screw.

4. Transmission part

Eccentric axis is the main axis of crusher under huge bend torsion, casting by high-carbon steel. The eccentric part should need the process of finish machining, thermal treatment and bearing liningtile casted by Babbitt metal alloy. On one end of eccentric axis equips with belt wheel, while on the other end of eccentric axis equips with flywheel.

5. Rack

The rack is open up and down with steel frame around, and it is used for supporting eccentric axis and bearing the anti-function of crushed material, which requires enough strength and stiffness. Generally the rack is casted of steel as a whole process but the small rack can use superior iron casting instead of steel. The large rack frame need melt by segmentation and connected by bolt with complex craft.

jaw crusher maintenance

As we all know the wear phenomenon is inevitable in the daily operation of jaw crusher, only do we regularly maintain the machine we can prolong the service life of a jaw crusher to the maximum. So we should maintain the jaw crusher shaft, the eccentric shaft and bearing for long-term!impact crushers

First of all, if the shaft wear is rare, you can do the turnery on the turning-lathe only to repair its geometry to make the shaft neck reach the correct geometry. And then correspondingly reduce the inner diameter of the bearing. However, after a few such treatment, the size of the shaft neck will decrease 5% of the original, then it cannot be turned any more, it should be replaced with new axis.

Once again, the jaw crusher is working in the shock load, the service life of the babbit alloy lining on the bearing is about two years at the maximum, if the service life exceeds the time limit, you will need to re-cast.
