• The Wet Ball Mill system ensures lime stone crushing upto particle size of 44 micron (325 mesh 90%). • Hydro cyclone is used to separate the limestone slurry at the wet Ball Mill outlet. • Each set of mill is equipped with a group of limestone slurry hydro cyclones, and can meet the requirement of limestone slurry fineness.

Nov 27, 2019· Once the limestone slurry is mixed with the required materials, it is fed into a wet process mill (slurry mill) where cold water is added to it. Water used in this process passes through a manually operated globe valve used as an on/off valve that also controls the rate of flow of water into the slurry mill.
