Hardness Testing For Ball Mill Balls

The hardness of the steel ball Knowledge

Keep the hardness right. When we choose wear-resistant steel balls, the hardness of the steel balls is often the problem. It is not the hardness of the steel balls that the larger the better, it is the appropriate hardness value.

The hardness usually ends up at 62 HRC. The stress relieving or drawing temperature is 325 ° F. This does not mean that this steel can be used up to this temperature. We have run repeated tests where we elevated the temperature to 325 ° F. In the first three cycles, the samples dropped one point of HRC each time they were treated.

The hardness of grinding media ball how to choose balls

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.

Impact testing for grinding balls is usually conducted by a ball on ball impact test using specialised equipment; however standard pendulum and drop weight impact tests may also be used for comparative purposes for quality control.

Introduction to Hardness Testing ASM International

Hardness Testing Theory Early methods generally consisted of scratching. Scratch hardness testing consists of penetration of the material surface by a testing point and bears a close resemblance to the indentation hardness test. One of the earliest forms of scratch testing goes back to Reaumur in 1722. His scale of testing con-
