Stone/Rock/Mining Crusher Wear Spare Parts Jaw/Cone/Impact/VSI Crusher Parts
We provide replacement parts for many brands of crushing plants. like, manganese liners,cone crusher mantle and concave(bowl liner), hsi bars and liners, blow bars, side liners, jaw liners, jaw plates, teeth plates, VSI wear parts, etc, for jaw crusher, cone crusher, impact crusher, VSI sand maker, etc.
We can provide custom casting service, based on the drawings from the clients.
We will make wooden mould, and sand cast the parts, after a series processes, you will get high quality wear parts in high manganese matching your machines.
1-Introduction of Jaw Crusher Parts
Jaw plate is manufactured with super high manganese steel, therefore it has a service life 50~100% longer than those made of traditional high manganese steel. Every model of PE series jaw crushers is tested for shock, stress, strain, thermal loading, deformation, vibration and noise under a wide range of load conditions. The special processing techniques ensure that our jaw plate has leading performance:
1)Using cold processing hardening technology, the hardness is improved.
2)Water toughening technology to avoid making the performance poor during the process of natural phase change.
2- Introduction of Cone Crusher Parts
which is designed to protect the Cone Crusher, thus improves the working life.We supply high qualified concave in high Cr, Mo, alloy steel for Cone Crusher.
Cone Crusher Parts
1. Spare parts for Cone Crusher.
2. Be used in manganese steel
3. We can do as per customer’s requirements.
We manufacture an extensive range of wear and spare parts in China for the worlds most popular crushing brands, like the spare parts for the below crushers.
1) Simple structure in linear type,easy in installation and maintation.
2) Adopting advanced world famous brand components in pneumatic parts,electric parts and operation parts.
3) High pressure double crank to control the die opening and closing.
4) Running in a high automatization and intellectualization,no pollution.
5) Apply a linker to connect with the air conveyor,which can directly inline with filling machine.
IMPACTOR BLOW BARS
What are Blow Bars?
Blow bars are thick slabs of metal, typically some mixture of chrome, that are forged for the purpose of effectively breaking apart material like asphalt, concrete, limestone, etc.
Blow bar is a critical part during the crushing process with horizontal shaft impactor. Materials of the blow bars are usually selected according to the function of the impact crusher.
When set in the horizontal impact crushers, blow bars are inserted into the rotor and rotated at high speeds, making the whole rotor assembly spins repeatedly striking the material. During this process, the blow bar fractures the materials until it meets the appropriate size to fall out through the impact crusher chamber.

Metallurgy of the Blow Bars
HONGFEI impact crusher blow bars are available in a variety of metallurgies to accomodate your unique crushing needs. The range of metallurgies includes Manganese, Low Chrome, Medium Chrome, High Chrome, Martensitic and Composite Ceramic.
As shown in the figure, an increase in the steel’s wear resistance (hardness) is usually accompanied by a reduction in toughness (impact resistance) of the material.
The wear resistance of manganese steel with austenitic structure is attributable to the phenmenon of work hardening. The impact and pressure load results in a hardening of the austenitic structure on the surface. The initial hardness of manganese steel is approx. 20 HRC. The impact strength is approx. 250J/cm².
After the work hardening, the initial hardness can thereby reach upto approx. 50 HRC. The deeper-set, not yet hardened layers thereby provide for the great toughness of this steel. The depth and hardness of the work-hardened surfaces depend on the application and type of manganese steel.
Manganese steel has a long history. Today, this steel is used mostly for Jaw plate, Mantle | Bowl Liner (mantles & bowl liners). In the impact crusher, it is only recommended to use manganese blow bars when crushing less abrasive and very large feed material (e.g. limestone).
With chrome steel, the carbon is chemically bonded in the form of chromium carbide. The wear resistance of chrome steel is based on these hard carbides of the hard matrix, whereby the movement is hindered by offsets, which provides for a high degree of strength but at the same time less toughness.
To prevent the material from becoming brittle, the blow bars must be heat-treated. It must thereby be observed that the temperature and annealing time parameters are exactly adhered to. Chrome steel typically has a hardness of 60 to 64 HRC and a very low impact strength of 10 J/cm².
To prevent breakage of chrome steel blow bars, there may not be any unbreakable elements in the feed material.
