Product Description

CHENDDA 
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.
 

High manganese steel, also known as Hadfield steel, its chemical composition includes high manganese (10%-15%) and high carbon (0.90%-1.50%) , usually carbon content of more than 1.0%. This kind of steel, because of its strong toughness, in the resistance to severe impact load performance, safety, reliability, can not be compared with other materials. high manganese steel under severe impact or contact stress, the surface will quickly harden, and the core to maintain extremely strong toughness, the external hard internal tough characteristics of both wear and impact resistance, is extremely advantageous. After the surface is worn, the secondary surface is hardened, , so this performance advantage is widely used in mining, metallurgy, industry, building materials, railway, electric power and other important environment.

High manganese steel grate plate is a kind of high strength steel, is mainly used to withstand impact, extrusion, material wear and other harsh working conditions.

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.
The value our products bring to the customers - doing more with less.

Corporate Vision
 

Gather strength, provide a platform for every striving person to achieve themselves, and create a world-class grinding supplier.
