Special Designed Hardening Hammer Beaters For Grinding Material With High Wear-Resistance

High-Efficient and Durable Hammer Blades: The Core of Hammer Mill

Hammer blades, as the key components directly contacting and crushing materials in hammer mills, play an irreplaceable role. Their performance directly determines the working efficiency of the mill.

The shape design of hammer blades is sophisticated. Currently, plate-shaped rectangular hammer blades are widely used due to their simple structure, easy manufacturing, and strong versatility. With two pin holes, they can flexibly rotate their four corners during operation, effectively extending the service life. Special-designed hammer blades, such as those with welded carbide or special wear-resistant alloys on the working edges, though more costly, significantly enhance wear resistance, suitable for severely abrasive working conditions. Hammer blades with trapezoidal, angular, or pointed corners are excellent for crushing fibrous forage but have relatively lower wear resistance. Ring-shaped hammer blades, with only one pin hole, can automatically change the working angle, ensuring uniform wear and a long lifespan, albeit with a more complex structure.

Materials and heat treatment processes are the core determinants of hammer blade performance. Commonly used materials in China include low-carbon steel, medium-carbon steel, and special cast iron. Low-carbon steel, after solid carburizing and quenching, is simple in process and low in cost, with a hard surface and flexible inner layer, providing certain wear resistance. Special cast iron, with easy access to materials, greatly improves wear resistance after chilling, but strict control of material composition and production processes is required to prevent breakage during use. Additionally, surface hardening treatments, such as surfacing tungsten carbide on working edges, can significantly extend the lifespan of hammer blades. Although the manufacturing cost increases, it offers high cost-effectiveness in terms of long-term use and production benefits.

The arrangement of hammer blades has a profound impact on crushing efficiency. A reasonable arrangement ensures that materials are evenly and efficiently struck within the crushing chamber, avoiding crushing dead zones. Meanwhile, strict precision control during the processing, especially in tungsten carbide surfacing, is crucial to fully unleash the performance advantages of hammer blades.

In practical applications, hammer blades demonstrate strong crushing capabilities, handling various materials, from grains, small pieces of bean cakes to chopped stalks and forage. In the feed processing industry, hammer mills, driven by high-speed rotating hammer blades, crush materials through collisions with toothed plates and friction with screens, producing feed products that meet the feeding and digestion requirements of animals, providing solid support for the efficient development of the livestock industry.

Selecting high-quality hammer blades means empowering hammer mills with strong core power, ensuring efficient, stable, and long-lasting operation in all crushing tasks, and creating greater production value for enterprises.
