Jinan Haoyang Forged Grinding Ball Co.,Ltd is the professional manufacturer and exporter for Forged Steel Grinding Balls,Grinding media and Casting Chrome Grinding Balls which is located in the largest production base of Forging Grinding Balls in China,We have exported many containers of Alloy Steel Grinding Balls to some countries,Finland,India,Turkey,Peru,Canada and Japan.We have got good feedback from our customers.For Forged Grinding Balls,recently,there are two kinds of production line,one is traditional forging technology with are hammer,the other is hot rolling grinding ball.if the size of the grinding steel ball is smaller then Diameter40mm,hot rolling ball is the best,and the production capacity is very large.if the size of the grinding media ball is larger then Dia40mm,generally speaking we often choose Traditional Forging,Electrical Stove is one of the most important equipment,the echnical personnel should control the hardness of grinding steel ball by controlling the temperature.after using the best material of steel,the surface hardness of the Dia25-40mm grinding ball can reach 60-64,also the core hardness is greater than 50.
Our factory has the quality guranteed measures for the grinding balls,if SGS Inspection before shipment,we will pay the fees no matter our customer required.if the steel grinding ball pass the SGS testing,the goods will be shipped in the port,it it is not qualified,we will cancell the orders and bear the transport fees from qingdao port to our factory.it is certain for our customer test the goods in our factory,we could provide with most of testing equipments.
