Sulzer Pumps, in Centrifugal Pump Handbook (Third Edition), 2010. Fossilfired flue gas and CO 2 scrubber pumps. Flue gas desulfurization scrubbers usually involve causing the flue gas to circulate through thin lime slurry in a contactor. The flow rates are large and the limestone slurry is abrasive. Depending upon customer preference, normal centrifugal or rubberlined slurry pumps are ...
Aug 01, 2006· Limestone reactivity is greatly influenced by particle size. A typical method of preparing limestone slurry is to grind the raw limestone with water in a ball mill. This produces a suspended ...
The FGD process begins as the limestone feed (rock) is reduced in size by crushing it in a ball mill and then is mixed with water in a slurry supply tank. The slurry (approximately 90 percent ...
a mill product tank. The mill product pump transfers the slurry from the mill product tank to the classifiers. The classifiers separate the limestone slurry based on particle size. When properly set up and operating, the fine material flows from the classifier overflow to a limestone storage tank where it is stored until needed by the FGD system.
3) Slurry composition in the tank is tested to give the required chemical composition and corrected periodically in the tube mill. 4) After that, the slurry is stored in the final storage tanks and to keep slurry inhomogeneous condition continuous the agitation is done in tank. 5) This homogeneous slurry is sprayed on to the upper end of a ...
tank is used to control feed of solid lime or limestone. Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. Lime slurry is more alkaline, having a pH of while limestone slurry is roughly neutral. A lime .
Limestone Mill Slurry Tank Limestone is fed by gravimetric feeder from limestone silo to wet ball mill 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 .
May 25, 2015· Limestone slurry preparation system is set with one limestone slurry storage tank, in which the slurry is fed into limestone slurry supply tank through limestone slurry storage tank. Each ball mill is set with 2 ball mill system slurry recirculation pumps, one .
Limestone is mined from a quarry in the form of calcium carbonate (CaCO3). Then it is crushed and fed into a kiln at approximately 2,000° F, where the carbon dioxide is burned off (calcining) to make calcium oxide (CaO). CaO is ground into a powder in a tower mill, a spiral classifier, or a slaker.

Limestone mill grinds limestone into powder, limestone powder has different specifications: It can be used to produce anhydrous calcium chloride which is the main auxiliary raw material of sodium dichromate production. It is the main raw material of glass cement production, it also can be used in the areas of building materials and poultry feed.
The wet ball mill process requires a considerable commitment by the power plant to operate a very inefficient process for crushed limestone handling on site and for operating inefficient wet ball mill processes requiring considerable operation cost, maintenance costs and energy costs with less than reliable slurry production.

The limestone slurry exits the CL Attritor Mill and enters the Separation Tank. 5. Any oversized particles are pumped back into the Mill while finer slurry overflows into the Mill Product Tank. 6. The slurry is then fed through a hydrocyclone with the under flow returned to the separation tank. SPECIFICATIONS
Nov 22, 2015· Limestone – gypsum slurry is pumped into the settling tank from the absorber is mounted on top of the nozzle header column in the limestone – gypsum slurry spray tower along the process of falling in contact with the rising smoke it. SO2 in the flue gas dissolved in water, and is one of the basic substance, so that the flue gas sulfur removal.
Limestone is fed by gravimetric feeder from limestone silo to wet ball mill 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.

The mixer assembly conveys conditioned limestone powder from a surge hopper located below the silo discharge, slurries the powder with water on a single pass to 30%+ solids and discharges the slurry into the slurry storage tank. Slurry makeup is on demand based on slurry storage requirements.
Jun 09, 2020· 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.
