Forged Grinding Balls Application industry
1. Ball Milling The Grinding Balls are produced from High Carbon or Alloy steel bars and then forged into balls or by Auto rolling machine improving the output.which are for use in mineral processing ball milling operations . Using the high carbon content and high hardness levels for maximum abrasion resistance . in nominal sizes from 1.0” to 4.0” in diameter.
2. SAG Milling Haoyang Balls range has some of the leading SAG ball products in the industry, that are specifically designed for today's SAG milling environments. Haoyang has developed a product with high toughness and superior wear life.
3. Ball Milling for Industrial Applications Haoyang manufactures grinding balls for use in industrial applications such as power and cement. The balls are manufactured from high carbon, alloy steel bars and then forged into balls.

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.
