Home; Grinding balls for mining - suitable for all mill applications. Grinding balls for mining are made from various metals such as steel, hard metal and ceramic.However, they are commonly manufactured from steel and steel alloys which have superior resistance to abrasion and low wear rates.Hardness might be between 15 and 66 on the Rockwell Scale or between …
Details 
In ball milling applications, the diameter of the balls, mill and throw action of the charge provides a low-impact environment– hence maximum abrasion resistance of steel balls is the desired characteristic. CHEMISTRY & HARDNESS High carbon content and high hardness levels affect abrasion resistance in steel balls.

Discussion On The Misunderstandings And Influences Of Grinding Balls Quality On Ball Mills Feb 10, 2018. Grinding Balls ball mill good quality both affect the size of productivity, but also affect the ball consumption level, thus affecting the cost of grinding media. Pure pursuit of high hardness low consumption is wrong.
Details 
Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.

Keep the hardness just right. When we choose wear-resisting grinding media ball, often be the hardness problem of the grinding media ball.About the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball loss.
