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.

MANGANESE STEEL

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 plateMantle | 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).

CHROME STEEL

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.

RFQ

Q1. What's your company's casting methods?

  A: We support sand casting and lost foam casting.

  Q2. Can you make products without drawing?

  A: No, we can only make products strictly according to customers'

      technical drawing. Because every spare parts must be install to

      the equipment even little error will make big problem.

  Q3. How about the lifetime of your wear spare parts?

  A: Different working condition make different results based on same

      products. You buy our products and try them, you will know our

      quality.

  Q4. What's the delivery time?

  A: Usually abroad brands' delivery time is 30 days, but if we need to

      make wooden mould, then 15 days more. Domestic brand's

      delivery time will be 20 days.

  Q5. What's the payment term does your company accept?

  A: T/T, L/C, Western Union etc.
