Haoyang manufacturing grinding balls of European quality :
Jinan Haoyang Casting & Forging Co.,ltd is one of the leading grinding media manufacturer in China .Our products are designed for grinding of raw materials by cement plants, energy generating companies, ore mining and industrial processing facilities, construction materials plants located in China . Haoyang steel balls manufacturing plant was put into operation in June 2008.Today, we deal with continuously growing consumer requirements for operational properties of grinding media, what directly affects ball mill prices and quality, efficiency of equipment and the enterprise in general.
The plant was built using the most advanced equipment. Through the use of modern technologies and cooperation with a number of research organizations, we managed to achieve very high levels of quality in grinding steel balls. Despite its short history, Haoyang managed to become a manufacturer of quality grinding media for ball mills, as well to keep its position on both the domestic and overseas markets .The operational properties of steel balls produced by Haoyang allow to significantly reduce the consumption of grinding balls and power, to increase grinding fineness of raw materials, to decrease the number of mill repairs and, consequently, to increase their productivity.
Grinding Media Balls For SAG Mill Specifications:
HY Grinding Media Balls are produced from High Carbon low alloy steel bars and then forged into grinding balls. The grinding balls are produced via Hot rolling machine or labor air hammer or Roll forging for larger diameter SAG balls
During production , we must control the chemistry and microstructure to reach the optimum wearing resistance and impact value . The diameter of grinding balls range from 3.5"-6" are classified as SAG grinding balls used in SAG mill operation .
Quality guarantee: Replacement of Broken grinding balls

Forged Steel Ball Mill Balls
The size of forged grinding media balls from 20mm to 150mm are widely used in all kinds of mills in the mining industry ( Copper Mining , Gold mining and iron mine )
Grinding Balls Features :
Steel : Low Carbon Steel , High Carbon and manganese Alloy steel , High Manganese Alloy Steel .
Consistant Surface hardness to Core Hardness ( 58-65HRC)
Grinding balls reach to the high Impact toughness more than 15J /cm2
The lowest broken rate : 125mm Grinding balls have reached to "0" broken rate ,all less than 0.5%
Improved wearing rates
Sizes: Haoyang manufactures grinding balls in nominal sizes from Dia25mm to Dia150mm. Grinding balls in the range of Dia 50mm to 125mm in diameter are classified as medium balls and are used primarily in ball mill operations.
Chemistry: An individual chemical profile has been developed for each diameter ball to correspond with the requirements for heat treatment. Specific alloy additions are included to produce optimum physical properties. The chemistry of the balls is controlled through a close collaboration with our bar suppliers and robust internal quality systems.
Surface and Volumetric Hardness (Rockwell C):
The wear resistance of the balls depends on the microstructure of the steel which is altered using carefully selected heat treatment variables specifically designed for each particular alloy. The control variable for the finish product is the hardness range.

Application Area
Mine
The ore grinding media usually comes out with the steel grinding ball and steel
Grinding rod. Its quality is the decisive factor affecting the operating cost of the mineral processing plant .
We could supply different steel grinding balls in line with different mines and diversified needs of the mineral processing plant. We can offer you the wear resistant steel grinding balls with the diameter ranging from 20mm to 140mm to fit for gold ore, Silver ore, cooper ore , iron ore, etc.. Those products get extensive promotion and applications in actual mining industry , and help the customers attain remarkable economic benefits by saying a lot of procurement cost and largely boosting the production output !
Cement Plant
The power consumption and steel consumption of the ball grinding mill occupy a rather high cost ratio in the production and processing process of a cement plant. The hardness , breakage rate and the corrosion resistance of the steel grinding ball affect the production cost and efficency of the ball grinding mill.
Electric Power Plant
The consumption of the steel grinding ball makes up the bulk of the operating cost in the electric power plant . It is very meaningful of how to find a way to reduce the cost and improve the efficiency .
Chemical And other Industries
We can according to the material to be groud provide the most appropriate wear resistant steel grinding balls to enhance the production efficiency of the ball grinding mill, and debase the production cost . Also availabe is the wear resistant steel grinding rod .
Haoyang have agent in Europe and providing grinding balls solutions for Gold mining . All the goods will be inspected in factory and then inspected in Loading
Port of china by SGS before loading on board . If unqualified , all the containers
Will be returned back to factory ! And we accept the claims caused by any problem of the steel .
