Crusher Hammer plays an important role in various fields, according to the different types of crushed materials, crusher Hammer

There are different classifications of Hammer Crushers. Crusher Hammer is one of the core parts of Hammer Crusher, which is arranged on the hammer shaft of the crusher rotor, and strikes the material directly during the operation of Hammer Crusher#Hammer Casting Process

What are the types of Hammer Crushers? What are their uses?

1、Forged Hammer

Forged crusher Hammer is suitable for crushing pebbles, gangue, limestone, etc. It is made of train hub steel (material: steel). Train hub steel (material 65Mn, good impact resistance, toughness, wear resistance, not easy to break), the use of forging machinery on the metal billet repeatedly forging, so that it produces deformation in order to obtain a certain mechanical properties, certain shapes and sizes, in the quenching of special heat treatment methods to ensure that the Hammer work area to get high hardness, high wear-resistant properties.

Through the forging can eliminate the metal in the smelting process produced in the cast state of loose and other defects, optimize the microstructure, and at the same time, due to the preservation of the complete metal flow, the mechanical properties of forgings are generally better than castings.

2、high fierce steel Hammer

Alloying high manganese steel wear-resistant Hammer, reliable quality, wear resistance for the traditional high manganese steel three times, the crusher Hammer is widely used in the new dry-process cement production line supporting the large limestone crusher.

With the continuous development of wear-resistant materials, high manganese steel has been gradually unsuitable for the development of the modern foundry industry, was replaced by chromium-molybdenum alloy steel, high chromium cast iron and nickel-hard cast iron, but high manganese steel’s high toughness characteristics of the other wear-resistant materials can not be compared . High manganese steel crusher Hammer toughness, good workmanship, low price, its main feature is in the larger impact or contact stress, the surface layer will rapidly produce work hardening, its work hardening index is 5-7 times higher than other materials, wear resistance has been greatly improved.

3、High chrome alloy Hammer

High chrome alloy crusher Hammer has excellent hardness, is a wear-resistant material, especially suitable for crushing high hardness materials, such as quartzite, basalt and so on. However, high chrome alloy toughness is poor, in the absence of hammer frame support is prone to fracture. High-chromium composite Hammer, that is, the use of high-manganese steel hammer handle, Hammer work area using high-chromium alloy, the two composite, so that the head of the Hammer has a high hardness, while the hammer handle has a high toughness, give full play to the respective advantages of the two materials to overcome the shortcomings of a single material, to meet the performance requirements of the use of Hammer.

4、Cemented carbide Hammer

Compared with other materials, Cemented Carbide Hammer has higher hardness, flexural strength and impact, thermal fatigue resistance, good thermal hardness, low cost and other characteristics, solving the high manganese material is prone to cracks, de-welding, chipping, dropping and so on.

Cemented carbide Hammer advantages:

1, ultra-high wear resistance, more than 20 times of high manganese steel Hammer .

2, has good resistance to mechanical shock, thermal shock performance.

3, Wide range of application, basically can be adapted to all the crushing industry.

5、Bimetal Hammer

Using two different metal liquid cast crusher Hammer is bimetallic Hammer, bimetallic Hammer in the hammer shank part of the toughness at the same time, the hammer head part also has a hardness, wear resistance.

Bimetallic Hammer quenching temperature is critical, generally in accordance with the thickness of the part wall to select the appropriate quenching temperature, the higher the quenching temperature, the higher the hardenability, so in the production of Hammer must develop a reasonable casting and heat treatment process.

If the crusher Hammer casting is not proper it will cause defects such as porosity. Crusher Hammer pouring system design is not correct, the metal liquid vortex will be wrapped into the gas will lead to the production of porosity; casting Hammer exhaust bad, the gas can not be discharged from the casting will also lead to the production of porosity which requires us to strictly control the temperature of the pouring, and in the pouring of uniformity can not be interrupted, in order to facilitate the casting of exhaust, you can use the tilt pouring.

Crusher Hammer after use will appear different degrees of wear, due to the low impact operating conditions, Hammer surface work hardening effect will also be intensified, Hammer wear refers to the role of mechanical forces, the metal Hammer surface gradually detached from the parent body, resulting in changes in the performance of the Hammer, the wear of the service life of the Hammer impact. #Hammer foundry from China

Zhejiang Jinhua Shanvim Industry and Trade Co., Ltd., established in 1991. The company is a wear-resistant parts casting enterprise. The main products are the wear-resistant parts such as mantle, bowl liner, jaw plate, hammer, blow bar, ball mill liner, etc.. There are medium and high , Ultra-high manganese steel, medium carbon alloy steel , low, medium and high chromium cast iron materials, etc.. It mainly produces and supplies wear-resistant castings for mining, cement, building materials, infrastructure construction, electric power, sands and gravel aggregates, machinery manufacturing and other industries.
