Sep 10, 2007 Each ball mill is fed at a rate of 70 th and operates 24 h a day. A constant flow of N 2 CO 2 inert gas prevents ignition of the ground coal and conveys fine material out of the mill. This gas mixture enters the mill at 650 C and leaves it at around 90 C.High wear rates were observed when using forged high-carbon steel balls.
Tube mills use steel balls as grinding media. Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady balanced ball charge in the mill. The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the ...
Dec 06, 2011 Re how to estimate the wear rate for Ball mill. Dear Mr. Pankaj, Thanks for finding my work on Grinding ball pattern software useful. I have developed few software for cement industry which are listed below. I would like to inform you that these software are
