As a trusted domestic foreign trade wholesaler, we pride ourselves on offering premium grinding media that meets the highest standards of durability and performance. By carefully selecting and loading the appropriate media for your operations, you can achieve consistent results, lower operational costs, and extend the lifespan of your equipment.
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.
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.

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

Shijiazhuang Chengda Wear resistant materials Co.,LTD. a certified ISO 9001Company, specializes in the design, development, production, and servicing of high chromium wear resistant materials for grinding equipment in cement, mining and quarry industries.
CHENDDA manufactures High chromium cast grinding media which is wear, corrosion and impact resistant helps in efficient ball mill grinding.
Our grinding media is tailor made for each milling application. There is a wide range of alloying options which are decided after adequate test work and technical analysis. We manufacture grinding media with chrome content ranging from 1 % to 30 % in sizes ranging from 15 mm to 140 mm as required by the application
Big balls, ranging from 140 mm to 60 mm, Chrome range from 10% - 28%,Optimal Hardness ranging from 57 - 66 HRc , are essentially used in the first chamber of the mills for crushing the feed material. These balls impart potential energy for crushing and thus required to possess a combination of wear and impact resistance
Grinding by attrition is accomplished by numerous small balls of varying sizes from 15mm to 60mm,Chrome range from 10% - 30% and Optimum Hardness ranging from 60 - 69HRc in second chamber. These balls contribute significantly to the grinding efficiency of the mills. Quality control of the final product depends much on the quality of the balls used.
Our commitment is to deliver reduction in wear cost, improve equipment availability, enhance mill productivity, reduce energy cost (Carbon foot-print) and improve metal recoveries through optimization in flotation process. With a legacy of more than 20 years in China , we have set benchmarks in quality, services and innovation, establishing a strong reputation as a solution provider.
