Grinding Balls China Introduction
The matrix of nodular iron is changed through isothermal quenching. It embodies high strength, super high toughness and wear-resistance. It has been widely applied in mining industry and is fit for mill.

Grinding Balls made by DSMAC Features
1. The abrasive resistance is higher than middle chromium ball, similar to high chromium ball, far outweigh low chromium ball.
2. The Ductility is more than all the ball of high chromium, middle chromium and low chromium.  
3. The rate of ball Broken is almost zero, no stoppage of Grate seam, and enhanced the efficiency of Mill powder.
4. Lost round rate is extremely low, greatly improved the efficiency of Mill powder.
5. As the specific gravity is only 7.1t/m3, 10% Lighter than normal metal, it will reduce 10 % of the capacity, 10 %to 15% power consumption and increase 5% of output.
6. Reduce mill noise 3-5 Decibel.
7. ”Free charged”: This kind of steel ball reduced at least 10% power consumption, only the Tons of cement node can enough offset  the  cost of  Every tons of cement ,so ADI grinding balls is called as “free charged” steel ball.
