The resulting mill slurry, containing both finely and coarsely ground limestone, is transferred to the corresponding storage tank and temporarily stored in the presence of water. To avoid spray line clogging by coarsely ground limestone, a classifier is used to ensure that only finely ground limestone is fed into the scrubber, and the limestone ...

silo into the ball mill using bin activator, screw feeder, and vibrating conveyor. Lime is then slaked via a ball mill (closed circuit) at a design rate of 11t/h. A milk of lime (MOL) slurry of 20% w/w is produced and then stored in an agitated tank (by others) where it is then dosed into the plant. The Lime Slaking System operates

limestone mill slurry tank. PowderLiquid Mixing to provide the most efficient Limestone Handling Slurry Processes for FGD The Technology offers many benefits over conventional slurry processes The VACUCAM Mixing Systems incorporate no mechanical mixing devices and has no moving parts other than liquid pumps

delivered to silo after unload system. Then limestone is fed to wet mill, the outlet slurry from mill is separated by hydrocyclone. Qualified slurry goes to slurry tank as the overflow of hydrocyclone. The basic process and configura-tion of wet mill system see Fig. 3.
