Anhui Ningguo Jinhong wear-resistant Materials Co. Ltd is a professional enterprise specializing in manufacturing the wear-resistant. With an occupying area of 20.000 square meters which located in the largest wear-resistant material production base of Asia--- NingGuo Zhongxi industrial park which adjacent to Huangshan,Shanghai,Hangzhou,Nanjing,Hefei city,and the Nanjing Lushang and Hangzhou xiaoshan international airport also provide the convenient air transportation conditons .Our company possesses more than 400 staffs ,strong technical focus .advanced production equipment and testing facilities with the over 20.000 tons annual output.Jinhong brand products mainly including High Chormuim Casting Grinding Balls,Low chromium Casting Balls and steel casting.We’ve got the approval of National Quality Monitoring Center (NACIS) and ISO9001:2000 Quality Control  System accreditation.The chemical composition tests are all according to the requirements of  GB223.1,GB 223.2,GB 223.3,GB 223.4,GB/T 223.5,GB/T 223.12,GB/T 223.18,GB/T 223.23,GB/T 223.26,GB/T 223.46,GB/T 223.49.

Rockwell hardness testing in accordance with GB/T 230.

Times of falling balls are more than 8000 or equal.

The rate of the broken ball is below or equal 1% in principle.

Our products are widely used in many fields,such as cement build materials,metal mine,coal slurry thermal power plant,chemical engineering,ceramic industry,dope industry ,light industry some as permaking and magnetic material etc.The grinding ball is high hardness,low breakage,low ware rate,low consumption and little fragmentation.The surface hardness of ball will be raise further in using the course,and the wear resistance would gather hard,so can raise mill machine production capacity at the same time,and raise cements ratio surface area and reclaim ratio of the extractive mine.

The hardness and chemical composition of our grinding balls as below:1.low chrome alloy grinding ballsSize:20mm-130mmHardness:HRC 48-60;Chrome content:1.0-3.02.high chrome alloy grinding ballsSize:8mm-110mmHardness:45Min;Chrome content:10-283.low&high chrome alloy casting barSize:8*10mm-35*45mmHardness:45-62;Chrome content:low chrome 0.3-1.5;high chrome 10-15

Our company aim at “always meet the needs of the clients”,provide custmomers the best pre-sales and after sales service.Hold the business philosophy of “Quality first .Intergrity-Oriented.Keep improving.Customer paramountcy”.
