Alumina Ceramic Balls as Cement Mill Grinder (Better Than Chromium Steel Balls)
Short description :Chemshun Ceramics alumina balls as grinding media for cement , mineral , ceramics grinding .
Detailed Description:
With the advantages of high density , low cost , excellent abrasion properties . Chemshun
alumina ceramic grinding ball becomes an ideal media instead of traditional high chromium steel balls as cement mill grinder.
Appearance:
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 20ºC
-- 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
