plants in the country are expected to be provided with wet limestone based FGD system. I am glad that CEA has finalized the document titled, "Standard Technical Specification for Retrofit of Wet Limestone Based FGD System in a Typical 2 x 500 MW Coal Based Thermal Power Plant" with valuable inputs from the committee members.
LM Vertical Mill integrates crushing, drying, grinding, classifying and conveying together, and it is specialized in processing non-metallic minerals, pulverized coal and slag. Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly. Applications: Cement, coal, power plant ...
maximize this rate. The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent

Attrition Mill System Layout Options,Energy Efficiencies …. A typical recirculation load for an attrition ball mill processing limestone with a bond work index of 10 and a feed particle size of 1/4"x 0"is between 140 to 150%.
Summary：MTW138 series European trapezium mill is a new generation of flue gas desulfurization (FGD) equipment with the world's advanced level for limestone mill. Desulfurization Of Flue Gas The flue gas desulfurization (FGD) plant removes sulfur dioxides (SO 2 ) from flue gas produced by boilers, furnaces, and other sources.
The grinding balls used in both CL and CLS machines are 51200 chrome steel or through-harden carbon steel. The fineness requirement in FGD systems generally is 95% < 325 mesh, therefore the CLS lime slaking machines generally use 5/16" or 3/8" balls to grind down the grids, and the CL limestone grinding machines utilizes 1/2" balls to ...
• Limestone grinding −Horizontal/vertical wet ball mills −On-site vs. off-site preparation • Product ground to 90-95% < 44 μ; 30% solids • Rubber-lined with hardened steel balls Limestone Preparation WPCA Wet FGD Seminar - December 1, 2008
For this, power plants are installing Flue Gas Desulfurization Plant (FGD) or unit. Limestone slurry is sprayed on the incoming flue gas. The sulphur dioxide gets absorbed. The limestone and sulfur dioxide react as follows : CaCO 3 + H 2 O + …

CLS Attritors – Stirred Vertical Ball Mill Lime Slaker The patented CLS Attritor Stirred Vertical Ball Mill Lime Slaker operates in continuous processing mode and has been used successfully in power generating plants for flue gas desulphurization (FGD). The Attritor will slake the lime as well as grind the inert grit, eliminating grit separation and […]
Haiwang hydrocyclones are used to classify the ball mill discharge, returning coarse particles to the ball mill for further grinding. Finely ground limestone (typically 90% passing 45 micron) reports to the cyclone overflow and is stored in a limestone slurry storage tank (at 25-30% solids by weight).

Wet Lime FGD. The process of wet scrubbing typically utilizes an alkaline-based slurry of lime to scrub gases. A shower of lime slurry is then sprayed into a flue gas scrubber, where the SO2 is absorbed into the spray and becomes a wet calcium sulfite. One by-product of that sulfite is it can be converted to salable gypsum.
Throughout the years, CEMTEC has gained extensive experience with grinding mills for countless wet and dry applications. Therefore, we have been able to offer ideal packages for grinding plants aimed at the production of limestone suspensions since 2001. Such plants are used in coal power stations with flue gas desulfurization by an FGD facility.
