What's more, the energy consumption of raw material grinding in the wet process is reduced by nearly 30%. Disadvantages: the heat consumption of the wet process is too high, usually between J/kg and the consumption of ball mill vulnerable parts is also large. Compared with other processing methods, the clinker manufactured by the ...

Lime silica and alumina get recombine. The fused mass turns into a nodular form called clinker. The clinker drops into the rotary cooler, where it is cool under control conditions. The cool clinker is then ground in a ball mill with the addition of 2 to 3% of gypsum. In the ball mill, particles crush to a fine powder and filled into bags.
