Grinding Balls For Mining SAG Balls Forged Ball Steel Ball Grinding Media
HUAFU manufactures grinding balls to exacting internal specifications at its grinding media production facility across the globe. Balls for use in mineral processing ball milling operations are designed for maximum abrasion resistance using high carbon content and high hardness levels.
· Single ball hardness difference between surface and core is small ( less than 2HRC );
· Hardness difference between balls is small (less than 2HRC ) .
· Hardness difference between various batches is small (less than 2HRC).
· Approximately unbroken, and the actual breakage rate is ≤0.5% after the impact of 10m falling ball is more than 10,000 times.
· Due to the optimization of quenching and tempering heat treatment process, the microstructure and hardness distribution of steel ball from surface to core is very uniform. During the wearing process, the ball can maintain in good shape.

Steel Grinding Rods have a wear resistance effect that is 150% stronger than that of rolledsteel bars.
They have excellent wear-resistant properties.
They are strong and more durable.
ln Grinding media Steel Rods are used in metallurgy and mining for grinding the ores suchas iron, copper,and gold.t is used for the processing of extracted minerals.
Rod mills produce less grit and slime, lighter crushing, and a product with consistentparticle size.
Main products: Forged steel ball,Heat-treated grinding rod,Liner for mills,Casting iron ball,Casting Cylperbs,Forged steel cylperbs,Carbon steel ball,patented production line for forged ball,patented production line for grinding rod;
The forged grinding steel ball has its advantage in surface,impact resistance, toughness,low breakage and low out-of-round rate. We use the most advanced forging methods and the advanced equipment to press onto the steel raw material ,so as to obtain the forging piece with certain mechanical properties, shape and size.
By forging, the defects of casting porosity can be eliminated, and the microstructure can be optimized. At the same time, the mechanical properties of the forgings are better than those of the castings of the same materials because of the preservation of the complete metal streamline. Choosing the most wear-resistant metal materials is very important for producing Forged Steel Ball. Our company independently R & D HM series wear-resistant alloy steel materials, it can be adapted to various types of forged steel ball.
Forged Steel Ball has its feature of grinding cost-effective, long service life, low breakage, low out-of-round rate and other features won the majority of mine users, such as the international mining giant Rio Tinto, BHP Billiton, Anglo-gold Corporation, etc. They are all using our new material forged steel ball.
We compare the cast steel ball with the forged steel ball. The results show that the wear of the steel ball is reduced and there is no out-of-round crushing, and the amount of ball used for grinding a ton of ore is reduced by 20% to 30% .
