Product Description

High-quality steel grinding balls ensure optimal performance by maintaining their shape and size even after extensive use. This consistency is critical for ensuring the uniformity of the final product and minimizing operational downtime. By sourcing your grinding balls from a trusted foreign trade wholesaler, you can enjoy a reliable supply of premium grinding media that meets your specific needs.

Optimal use of grinding media can significantly extend its lifespan, ensuring that you get the most out of your investment. For both grinding cylpebs and grinding media rods, it is crucial to use the media in the right applications and avoid overloading the mill. Overloading can lead to excessive wear, causing the media to degrade faster and reducing its effectiveness.

 

High chromium cast iron hammer casting process, the use of quenched high chromium cast iron hammer, stable performance, safe and reliable, and can improve the impact resistance and wear resistance of castings.

High chromium cast iron is the third generation wear-resistant material developed after high manganese steel and nickel hard cast iron, and its high performance represents the high level of wear-resistant materials at present. High chromium cast iron making cement industry ball mill liner, known for its high strength, toughness, high wear resistance. Cement ball mill liner using high chromium cast iron material general service life of 6-12 years (one warehouse), stable production and application, high reliability, for the cement industry to provide energy saving, consumption reduction and efficiency.

Chengda can provide diameter 4.6mm-140mm and the chrome content ranges from 0.8%-28%,which can be customized according to different needs of users.
It not only improves the grinding efficiency,reduces the time of stopping the grinding machine for selection and adding of the balls,but also extends the clearance cycle,reducesthe labor intensity,and has important significance for improving the output of themill,ensuringthe quality of the abrasive,and reducing the consumption of power consumption and the grinding media.

 

Mining balls are one of the most widely used types of grinding media in the mining industry. Made from steel, they are specifically designed for high-impact grinding applications. These balls are essential for breaking down larger rock and ore particles into finer, more manageable pieces.

 

When it comes to the mining process, the size and material of the mining balls are crucial. The right balance ensures that the balls will provide maximum impact force to break up the material, while also resisting wear and tear over time.

 

Choosing mining balls of the right hardness and size will optimize the grinding efficiency and help reduce the energy consumed in the process. This will, in turn, reduce operational costs and increase the lifespan of your equipment. For serious mining operations, the right grinding media is not just an option-it's a necessity.


 

High chromium wear-resistant steel forging is widely used in industrial fields, especially in the powder preparation and ultra-fine deep processing in cement, mining, coal slurry thermal power and other industries, which improves the grinding efficiency, reduces the shutdown time and the number of times of opening and shutting down, extends the clearance cycle, and reduces the labor intensity of workers. At the same time, it is of great significance to increase the output of the mill, ensure the quality of the abrasive, and reduce the power consumption and the consumption of the grinding body.

Excellent wear resistance: The chemical composition of the high chromium alloy wear layer has a high carbon content, and the chromium content is as high as about 30%, the volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, and the macroscopic surface hardness is HRC56~62, which makes its wear resistance significantly improved.

Good impact resistance: the substrate is low carbon steel or low alloy steel and other ductile materials, wear-resistant layer combined with the substrate, showing good impact resistance, suitable for bearing high drop hopper and other impact and wear material handling system.

Good corrosion resistance: Because the alloy layer contains a high percentage of chromium metal, it has a certain rust and corrosion resistance, which is suitable for the occasions of easy adhesion materials
