The Vertical Grinding Mill is used for wet grinding limestone for flue gas desulphurization. The process uses limestone feed stock of approximately 6mm in size and wet grinds the limestone to 95% minus 325 mesh. The grinding circuit includes the separation tank, mill recirculating pump, mill product tank, hydrocyclone, hydrocyclone feed pump and all necessary controls. Due to the grinding mill’s high efficiency, the power consumption for this mill is 50% less compared to conventional ball mills of a similar size. This results in substantially lower operating costs.

The Limestone Grinding Process:

The process begins with 1-1/2" limestone, which is fed from the silo to the crusher.

The limestone is reduced to 6mm pieces in the crusher.

The crushed limestone is then mixed with water and fed into the vertical grinding mill.

The limestone slurry exits the vertical Mill and enters the Separation Tank.

Any oversized particles are pumped back into the Mill while finer slurry overflows into the Mill Product Tank.
