jaw plates: how to choose the right one for different types of jaw crushers | fote machinery

The jaw plate is an important part in the jaw crusher equipment, and its service life directly affects the whole jaw crusher equipment. Therefore, you must consider the hardness and toughness of the jaw plate when you want to choose a correct one.

The wear of jaw plate depends on the types of your material and other variables such as material sizes. Too many fines enter the jaw crusher cavity will accelerate the wear speed of jaw plates because the fines fills the valleys which is necessary for the crusher to crush efficiently.

Generally, a jaw crusher finishes the crushing process by squeezing the material between stationary and moving jaw plates. The peaks and valleys of the jaw plates are offset from one another and use the mechanical advantage of leverage to break the rock.

Without this, the crusher has to rely on energy and friction to crush the rock. The compaction will also impose increased loads on the jaw crusher plates as much as five times the normal crushing force.

If the feeding material is over-sized, it also seriously affects the service life. In most applications, the reduction ratio of a jaw crusher is 6 to 1. Exceeding the reduction ratio will generate the crushing forces that break the crushers design limits and affect your overall production and machine performance.

That the jaw plate is severely worn can lead to uneven particle size and low efficiency, which indicates that you have to replace the jaw plates. If you want to choose a correct one, you should consider their different materials according to the purpose and real situation.

High manganese steel contains a relatively high carbon content which plays an important role in wear resistance. In general, the hardness increases with the growth of carbon content. Under non-strong impact conditions, increasing the carbon content is beneficial to improve the wear resistance of steel. And this is why high manganese steel has good deformation hardening ability.

Medium manganese steel has strong hardening ability and stable performance, which creates the function of self-protection when the law plates are subjected to impact and wear. The medium manganese steel jaw plate has achieved good results in the actual production process, and improves service life by 20% compared with that of the high manganese steel jaw plate.

Medium-carbon-low-alloy cast steel is a widely used wear-resistant material at present. Mainly because of its high hardness and suitable toughness, it can resist fatigue spalling caused by repeated extrusion of materials, and shows good wear resistance.

It can also be adjusted by composition and heat treatment to make the hardness and toughness be changed within a large range. That shows high flexibility strong adaption to the requirements of different working conditions.

The hardness of the material-The hardness of the material is also an important factor in choosing the jaw plate. The material hardness determines the toughness and strength requirements of the corresponding jaw plate.

For large jaw crushers, the crushed material is huge-block, which forces the jaw plate to accept strong impact and wear. For that situation, the high manganese steel can give full play to the advantages of good toughness and hardness.

Note: If the flare angle between the moving and fixed jaw plates is too large, it is easy to cause the sliding of the abrasive, deformation and insufficient hardening of the high manganese steel. So sometimes you should adjust the appropriate flare angle during use.

If you need to deal with materials with high hardness such as granite, quartz stone, concrete, etc., the medium manganese steel is the most suitable because of its strong hardening ability. Besides, it has a self-protection mechanism when crushing high hardness materials, which can greatly reduce the wear rate.

Medium and small sized jaw crushers usually bear a low impact load, so under such conditions, medium-carbon-low-alloy steel materials are more suitable. Not only can the disadvantages of high manganese steel difficult to reach the application hardness be avoid, but it also bring good technical and economic benefits.

jaw crusher market: global industry trend analysis 2012 to 2017 and forecast 2017 - 2025

A crusher is a machine which crushes the large rocks into smaller one, gravel or a rock dust. A jaw crusher uses force for crushing the rocks. This force is achieved with the help of a fixed and swing jaws. These Jaw crushers are heavy duty machines. The primary use of jaw crusher is in mining and building materials. It is also used in waste management and recycling process. Various leading manufacturers and growing number of end-use industries favor the demand for the global jaw crusher market. The major factors such as wide commercial and industrial applications and technological advancement the global jaw crusher market are expected to gain traction in the forecast period 2017-2027.ssssss

The major factors that are responsible for the growth of jaw crusher market are technological advancement and innovation. There are various latest models of the jaw crushers that attracts different types of potential customers. The advent of technology in the features of jaw crushers has created a positive outlook for the global jaw crusher market.

Jaw crushers is mainly used for crushing and crushing of various materials with compressive strength not exceeding 320 MPa. The Jaw Crusher has been widely used in mining, metallurgy, chemical industry, building materials, highways, railways, water conservancy and other industries.

The motor drives the belt and the pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the included angle between the bracket and the movable jaw can be large, so that the movable jaw plate approaches the static jaw plate, and the broken material is When the jaws descend, the angle between the elbow plate and the jaw becomes smaller, and the distance between the jaws and the spring plate under the action of the tension bar and the spring is enlarged. The broken material has been discharged from the lower end of the crushing chamber. With the continuous rotation of the eccentric shaft, a periodic reciprocating motion is performed. The material entering the crushing chamber is broken and discharged uninterruptedly. Realize continuous production.
