Study of the Hardening-toughening Heat Treatment Process of High Chrome Cast Iron Grinding Balls (1)

/in , /by

Abstract： The influence of quenching-tempering heat treatment, conventional austempering heat treatment and multi-stage austenitizing austempering heat treatment on the microstructure and property of high chrome cast iron grinding balls were comparatively investigated. The results show that the impact toughness and impact fatigue resistance of the grinding balls are higher after austempering. The austempering heat treatment […]

What are the types of grinding media for Ball Mills

/in /by

There are many different kinds of grinding media used in ball mills, such as forged grinding media and cast grinding media. Among them, forged grinding media are called forging balls for short; cast grinding media are called casting balls for short; cast grinding media are divided into high, medium, and low chrome. Today, the main […]

Ball Mill balls Sorting And Seperating Machine

/in /by

The sand is separated and filtered by the vibrating sieve, and then the casting is rolled into a high-speed rotating barrel. The separated casting ball mill balls and the gating-risers enter into the vibration sorting mechanism at the same time. The ball and the gating-risers are classified by the principle of vibration conveying. The results […]

The hardness of grinding media ball

/in /by

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. […]
