76mm grinding medial steel ball 6 meter fall drop test: More than 20,000 times, No Break

We request our local steel rod promise us on compressional rate ? See below picture:

Why do we request the compression rate 15 time at least ? Because we need to promise the steel rod have a high density to match the hot rolling method. 

Our production flow picture on 76mm grinding media steel balls for mining:

1.Steel rod automatic feeding to induction;

2.Steel rod heating to requested temperature by induction furnace;

3.Heated steel rod go into hot rolling machine to make grinding balls;

4.Hot grinding balls slow cooling on convey;

5.Grinding balls cools to right temperature and go into quenching system;

6.Grinding balls after quenching, cool again by convey and send into automatic tempering furnace;

7.Grinding balls do tempering treatment by correct temperature and time upon ball size in automatic tempering furnace, go into cooling plate;

8.Grinding balls after tempering treatment, will cool to room temperature;

9.Do the packing for grinding balls, in ton bag or iron drum.
