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.

 

The main advantages of high chromium alloy hammer head include strong resistance, long life, casting precision, widely used.

Strong resistance, long life:  high chromium alloy hammer by adding ultra-high wear-resisting alloy, has the advantages of impact resistance, pressure resistance, wear resistance, deformation resistance, its crushing effect is higher. The service life of high chromium alloy hammer is 3-5 times longer than that of high manganese steel, rail and so on .

Casting refining:  composite casting process, adding a variety of resistant metals, by outside furnace refining, metamorphic treatment and other special methods, can be customized casting according to the requirements of drawings. high chromium alloy hammer head is not easy to break with the hammer handle, effectively improve work efficiency.

Widely used:  high chromium alloy hammer contains a certain amount of chromium and carbon, makes the hammer hardenability is higher, suitable for metallurgy, mining, chemical industry, cement and other industrial fields, is the market generally recognized and accepted products.

In addition, Cr26 high chromium composite hammer adopts high chromium alloy lost die composite casting process, is equipped with a variety of precious metal elements, after special treatment, Rockwell hardness reaches 62-65, makes the service life of the hammer doubled. This kind of hammer not only has excellent wear resistance and high hardness, also has high toughness and strength, is suitable for crushing high hardness materials, can reduce the maintenance cost of equipment
