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.
Raw Material Quality Guarantee
Haoyang has established strategic relationships with our local steel plant or supplier allow us to guarantee all the grinding balls supplied to our customers are made from the highest quality steel and meet strict specifications. Each batch of balls will be recorded via Steel Heating Number for the following track.
