Our successful case

In 2016 season, we get the hornor to help one copper mine owned by China Gold Group, they told us that the 40mm grinding balls have a high ball consumption per ton of copper mine at grinding phase 2, because they know that we had developed our unique and special heat treatment.

The entire testing period last 3-4 monthes, we produced for this copper mine about 800 tons 40mm grinding balls, the result show as below:

After the testing, the copper mine under China Gold Group start long time cooperation with us, we help them to reduce ball consumption from 750 grams to 630 grams, which means 16% reduced!

Why the same raw material get so bigger different result ? Because we are keeping developing the newest and best production method year by year, our unique heat treatment method is special than others!
