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.
Full-Range of Metal Shredder Wear Parts
Pin Protectors
Pin protectors protect the long pins that secure the hammers in place. Not only they shield hammer pins, they reduce wear and tear on rotor disks. Pin Protectors also add vital mass to the rotor to preserve kinetic energy input by the motor.
Bottom Grates
Bottom Grates
The bottom grate ensures that shredded metal does not leave the shredding zone until shredded metal pieces are reduced to the desired size. The bottom grate sustains substantial abrasion and impacts from the rapidly moving metal inside the metal shredder. Bottom grates are often replaced at the same time as anvils and breaker bars.
Liners
Liners
Liners which include side liners and main liners internally protect the shredder from damage by the metal being shredded. Liners sustain substantial abrasion and impacts from the rapidly moving metal inside the metal shredder.
Caps (rotor and end discs)
Caps (rotor and end discs)
Rotor and end disc caps protect the rotor from damage by the metal being shredded. Depending on shredder size, caps can weight hundreds of pounds. Caps are replaced after about 10-15 hammer replacements, or about every 2-3 weeks of operations.
Breaker Bars / Anvils
Breaker Bars / Anvils
Breaker bars provide internal reinforcement against the impact force of hammers on metal being shredded. Anvils provide an internal surface where feedstock material is introduced into the shredder and initially impacted by the hammers.
Reject Doors
Reject Doors
Reject doors allow removal of unthreadable material and sustain substantial abrasion and impacts from metal being shredded.
Front Walls
Front Walls
Front walls sustain substantial abrasion and impacts from metal being shredded.

MINREQ is a full-range supplier of metal shredder wear parts. We have cooperated with the leading shredder operators all over the world for more than 8 years. With mature material and metallurgical technology, we can truly provide customers with reliable yet affordable products.
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.
