production of limestone slurry by grinding for flue gas desulphurization plants (FGD plants). ThyssenKrupp Fördertechnik builds and delivers for the wet grinding of limestone wet ball mills with a tube diameter from. 1.8 to 4.0 m and a throughput from 5.0 to 70 t/h limestone. The feed material is ground in the tube mill under

The CL 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 in the Premix Chamber and fed into the CL Attritor Mill. The limestone slurry exits the CL Attritor Mill and enters the Separation Tank.

Aug 30, 2012· Cement Manufacturing Process Phase II: Proportioning, Blending & Grinding. The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay.

Predicting Viscosity of Limestone–Water Slurry Pradipta Kumar Senapati*a, Dibakar Panda b, Ashutosh Parida a a Institute of Minerals & Materials Technology (IMMT), Bhubaneswar-751013, India b Department of Chemical Engineering, C.V.Raman College of Engineering, Bhubaneswar-752054, India

The rheological behavior of limestone–water slurry samples was investigated for different volume concentrations, particle size distribution and slurry temperature. Experiments were conducted over a range of volumetric solids concentration (Q= 0.20 - 0.46) in shear rate range of 1-300 s -1 . The slurry showed Newtonian behavior up to a volumetric solids concentration of 37.8 vol. %, beyond ...

Early grinding technology was poor, and early slurries were made thin, with a high water content. The slurry was then allowed to stand in large reservoirs ("slurry-backs") for several weeks. Large, un-ground particles would drop to the bottom, and excess water rose to the top.

The limestone slurry from wet ball mill shall be discharged to mill overflow tank. Grinding water for the limestone ball mill shall be ratio controlled by the signal of gravimetric feeder to maintain specified solid content at outlet of mill hydro cyclone. Limestone slurry from mill overflow tank is pumped via
