with varying baffle spacing, slurry of calcium carbonate (CaCO3) of 5 wt % in water was prepared and feed it to the slurry tank. Adjust the flow rate of the mixed solution (water + slurry) to a starting value of 7 L/min by setting the water flow …

Best Solution for Handling Lime Slurry | Manufacturing.net

Nov 08, 2010 · 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.

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three …

Slurry Density - Engineering ToolBox

Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 - c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l = density of liquid without solids (lb/ft 3, kg/m 3)

Sibelco - Calcium carbonate | GCC, PCC

It is commonly used medicinally as a calcium supplement or as an antacid. Precipitated calcium carbonate (PCC) is also a product derived from lime, which has many industrial applications. PCC is made by hydrating high-calcium quicklime and then reacting the resulting slurry, or “milk-of-lime”, with carbon dioxide.

Frontiers | Performance of Separation Processes for ...

Precipitated calcium carbonate (PCC) is also used in papermaking as a coating and filler material. In conventional production of synthetic (i.e., precipitated) calcium carbonate, flue gas containing CO 2 is bubbled though a hydrated lime slurry (calcium hydroxide), from which calcium carbonate precipitates. By adjusting the precipitation ...
