Six Advantages of Alumina Grinding Media Instead of High Chromium Steel Ball For Cement Mill Application:

1) Save Power

-- Reducing the mill loading 20%

-- Saving power above 15% per ton cement

2) Improve quality

-- Improve the grinding efficiency

-- Improve the performance of cement

-- Rationalize the grains distribution more better

-- Increase 2% of the grain 3-32 μm

-- Improve the spheroidization efficiency

-- Decrease 1~2% water in same standard consistency

-- Adapt the concrete admixture for cement well

3) Reduce Current

-- The current of mill mainframe is reduced by more than 20%

4) Cooling and noise reduction

-- The temperature could be down more about 20℃

-- Good effect of noise reduction

5) Excellent abrasion

-- The abrasion loss of chemshun alumina grinding media for cement mill is about a half of steel ball

6) Protect environment

-- Using of chemshun alumina grinding ball could protect environment effectively
