ball mill and screening of different ores

Cement, How It Is Produced

Cement, How It Is Produced

Once the ore material to be used for cement has been mined, it is transported to the crushing/screening plant, where it is crushed and screened, to produce the desired particle size. Ore from the mines are typically reduced to about ¾ inch and stored in a coarse stockpile. From there, the ¾ inch ore is typically reduced to a powder in a large ball mill.
