Hammer Mill Wear Parts

When it comes to Replacement hammer mill wear parts, Qiming Casting has been crushing the market for decades. If you demand the peace of mind that comes with ISO 9001-certified, fully-guaranteed and warranted replacement parts for your hammer mill.

Tough. Durable. Cost-efficient. Qiming Casting offers design and wear life analysis with three common alloys for improved wear life: Mn18Cr2, 30CrNiMo and TIC Insert alloy steel.

High Manganese Steel Hammer


High manganese steel hammer ensures the highest possible wear life is combined with mechanical reliability and numerous mounting possibilities. Thanks to the accurately balanced structure, the Qiming Casting manganese steel hammer is easy and economical to install.

As a high manganese steel grade, it offers excellent work hardening properties. High manganese steel plate becomes increasingly hard when the surfaces of components are subject to repeated impact or abrasion. Its toughness, derived from high tensile strength and ductility, enables shock leads to be absorbed safely. Lack of lubrication or the intrusion of grit or sand particles does not seriously impair the wearing surfaces of components in contact. These characteristics combine to make high manganese steel plate an ideal steel for use as wearing plates in those situations where abrasion, impact, or lubrication difficulties are encountered. The steel has the unique property in service of rapidly developing a work hardened surface whilst retaining its tough interior.

30CrNiMo Alloy Steel Hammer

30CrNiMo Alloy Steel Hammer

30CrNiMo Low Alloy Steel hammers provide longer life and often better value for operations that don’t run a steady diet of autos and heavier scrap that work hardens manganese hammers. Our 30CrNiMo Low Alloy Steel hammers offer hardness at the working end and less hardness around the hammer’s pinhole. The compromise provides for less wear on hammer pins. By using this material, the shredder hammer can get different hardness: The bar of shredder hammer’s hardness around: 35-40 HRC, The working area of shredder hammer’s hardness around 45-55 HRC.

Chemical Composition Of 30CrNiMo Hammer

C Si Mn Ni P S Cr Mo
0.26 – 0.34 max 0.4 0.5 – 0.8 1.8 – 2.2 max 0.025 max 0.035 1.8 – 2.2 0.3 – 0.5

TIC Insert Hammer

This new type high manganese steel crusher hammer with tic cermet rod is a good substitute for high chromium cast iron complex crusher hammer. It solves the problem of easy to be broken with high hardness in high chromium crusher hammer, furthermore, the wear life could be increased -up to 3 times, delivering fewer change-outs, more uptime, and lower maintenance costs.


  • Made to exceed OEM standards.
  • Efficient cast design is superior vs. other other hammers prone to deforming and cracking.
  • Stronger alloys = longer wear life and fewer part change outs

Customer Feedback

Case Study 1: Recycling Plant, hammer mill

Before: In one clinker cooler campaign at Lehigh Inland Cement’s production plant in Edmonton, AB, original hammers in manganese with hard surfacing delivered a wear life of 11.5 months.

After Switching to Qiming Casting TiC: Qiming Casting hammers with 40mm TiC inserts therefore outperformed the previous parts by more than 2.5 times.
