2. GENERAL DESRIPTION OF LIMESTONE GRINDING SYSTEMS (LGS) The purpose of this system is to grind lump limestone of Size 25 mm (Max) to powder and for preparation of limestone slurry. The duct from the limestone silo hopper feeds the limestone to the gravimetric feeder. The Gravimetric feeder feeds limestone to Wet ball mill system.

Wet/dry Interface: •Occurs in area of absorber where hot flue gas is quenched •Scaling results from fluctuations in gas flow and gas distribution. Causes areas along duct walls or other internal structures to vary from wet to dry •If slurry is carried back into this area, it may dry and accumulate as a hard scale composed

CALCULATIONS AND ANALYSIS. Calculate the mass of the dried precipitate, CaC 2 O 4 •H 2 O. ; Calculate the moles of CaC 2 O 4 •H 2 O you produced.; Since each molecule of CaC 2 O 4 •H 2 O contains one atom of calcium, the moles of calcium contained in your sample of limestone equals the moles of CaC 2 O 4 •H 2 O produced. Use this fact to …

are limestone, quicklime, and hydrated lime. Limestone is rock composed of at least 50% calcium carbonate and various impurities. A common im-purity is magnesium carbonate; when present in less than 5%, the limestone is referred to as high-calcium. A lime-stone containing 30-45% magnesium carbonate is classified as dolomitic stone.

A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows:

Calcination of CaCO3 is a highly endothermic reaction, requiring around 755 Mcal of heat input to produce a ton of lime (CaO). The reaction only begins when the temperature is above the dissociation temperature of the carbonates in the limestone. This typically is between 780 deg C and 1340 deg C.

In the wet process, water is added to the raw mill during the grinding of the raw materials in ball or tube mills, thereby producing a pumpable slurry, or slip, of approximately 65 percent solids. The slurry is agitated, blended, and stored in …
