Product Description

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.

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.

Company Profile
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.
