4.8m Cylinder 4% Pitch 1200TPD Limestone Calcination Plant

Dolomite & Limestone Calcination Plant

Lime is the high-temperature product of the calcinations of limestone. Although limestone deposits are found in everywhere, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate. When the rock contains 30 to 45 percent magnesium carbonate, it is referred to as dolomite, or dolomitic limestone. Lime can also be produced from aragonite, chalk, coral, marble, and sea shells.

Dolomite & Limestone Calcination Plant for lime:

CaCO + heat 6 CO + CaO (high calcium lime)

CaCO @MgCO + heat 6 2CO + CaO@MgO (dolomitic lime)

Dolomite & Limestone Calcination Plant Process:

In some lime plants, the resulting lime is reacted (slaked) with water to form hydrated lime. The basic processes in the production of lime are: (1) quarrying raw limestone; (2) preparing limestone for the kilns by crushing and sizing; (3) calcining limestone; (4) processing the lime further by hydrating; and (5) miscellaneous transfer, storage, and handling operations.

Dolomite & Limestone Calcination Plant Features:

The heart of a lime plant is the kiln. The prevalent type of kiln is the rotary kiln, accounting for about 90 percent of all lime production in China. This kiln is a long, cylindrical, slightly inclined, refractory-lined furnace, through which the limestone and hot combustion gases pass countercurrently. Coal, oil, and natural gas may all be fired in rotary kilns. Product coolers and kiln feed preheaters of various types are commonly used to recover heat from the hot lime product and hot exhaust gases, respectively.
