Market research shows that incorrect dimensions often result from sellers not confirming specifications with buyers. To prevent this, our seasoned engineers will double-check your part dimensions by verifying the drawing of your hammer heads to ensure a 100% match with your hammer crushers.
A hammer head in a hammer crusher is a key wear-resistant part that applies impact force to materials through high-speed rotation, resulting in crushing. The durability of the hammer head is crucial for the crusher's efficiency. It's important to note that in horizontal impact crushers, the primary wear part, known as a blow bar, is also referred to as a hammer. Although their roles in the crushing process are similar, they differ in appearance and installation methods. Be sure to distinguish between the two when purchasing.
Although hammer crushers can crush stones into a single form without multiple stages, their maintenance is complex. The hammer head is uniquely installed, hanging on the rotor, and all sides are impacted by materials, resulting in a metal utilization rate of only 35%. The wear rate is high, and replacing the hammer heads, especially in large crushers, can involve over 100 hammer heads at a time. Therefore, selecting high-quality, durable hammer heads can reduce the frequency of replacement, minimize downtime, and lower operating costs.
Our drawing library covers more than 20 impact crusher brands, and before placing an order, our experienced engineers will double-check the dimensions of the impact plates.
Unlike the unstable supply sources of trading companies, our impact plates are self-produced and self-sold. We can guarantee that each batch of our impact plates is produced under high standards, and the production of each product can be traced back.
Our professional engineers will recommend the most suitable plate material based on the raw materials you need to crush, extend the service life, reduce the replacement frequency, and lower your operating costs.
With over 30 years of experience in hammer head production, we offer four distinct types of hammer heads tailored to different scenarios and material hardness requirements:
The high chromium iron head provides excellent wear resistance, while the high manganese steel handle offers superior toughness and impact resistance.
The toughness of the high manganese steel handle ensures more even distribution of impact force. The elasticity and toughness help absorb some impact energy, reducing direct impact on the hammerhead and minimizing wear and damage. This lowers maintenance costs.
Bimetallic composite hammerhead is suitable for crushing limestone, cement clinker, iron ore, sandstone, coal gangue, basalt, and more, especially in harsh mining conditions.
High manganese steel hammerhead's Mn content is typically around 12-22%. We offer manganese content ranging from 13-22% (Mn13Cr2, Mn18Cr2, Mn22Cr2 or customized).
High manganese steel hammerhead becomes harder with impact, offering high wear resistance. Initial hardness is about 200 HB (Brinell Hardness), and work-hardened hardness can reach up to 500 HB.
The high chromium iron head provides excellent wear resistance, while the high manganese steel handle offers superior toughness and impact resistance.
Pros: Excellent work hardening, very high wear resistance.
Cons: May become brittle with excessive impact.
Applications:
High manganese hammer head is recoammended to crusher hard and abrasive rocks with hardness up to 1500 MPa, like high-silica rocks, hard granite, quartzite.
High Chromium Content (Cr) of high chromium iron cast hammer head is typically around 12-30%. We offer high chromium cast iron with chromium content ranging from 20-30% (KmTBCr26, KmTBCr30 or customized).
The hardness of high chromium cast iron hammerhead is typically around 60-65 HRC.
High chromium cast iron hammerhead is more brittle compared to other materials, not suitable for high-impact environments.
Applications:
High chromium cast iron hammerhead is recommended forhigh wear but low impact applications like hard and abrasive materials with hardness up to 1800 MPa, such as silica sand, high-silica rocks, and iron ore.
High Chromium Alloy Hammerhead made from high chromium alloy, offering a good balance between hardness, toughness, and wear resistance.
High Chromium Alloy Hammerheadhas high wear resistance, typically around 55-60 HRC and is tougher than pure high chromium cast iron.
Applications:
High chromium cast iron hammerhead is recommended forhigh wear but low impact applications like hard and abrasive materials with hardness up to 1800 MPa, such as silica sand, high-silica rocks, and iron ore.
Depending on the material's wear resistance, select the highest grade KmTBCr26 or Mn22Cr2 hammer heads to reduce the frequency of wear part replacements, ensuring durability and efficiency.
