Date modified: The result is a chemical lime that will provide exceptional performance for your acid neutralization, flue-gas desulfurization, sludge stabilization or other industrial alkali applications. Granulated lime is a specially sized quicklime that meets exacting particle size specifications.

Granulated lime provides Graymont customers with a fine yet dust-free product. Ground lime is sized to meet particular specifications where a high-quality lime product is required. When customers demand a high-performance ground lime, Graymont can deliver.

BOF lime is specifically processed to meet the demands of integrated steel manufacturing. Our BOF-grade lime yields low loss-on-ignition, low sulfur and low fines content for optimum process results.

PCC lime provides superior chemical base performance compared to standard lime products. Graymont carefully monitors process control to produce high-calcium CaO that is highly reactive and has exceptionally high brightness. Not all of these products are available at all plants. Quicklime, the product of calcination of limestone, consists of the oxides of calcium and magnesium, and in Canada it is available in three forms: High calcium quicklime--derived from limestone containing 0 to 5 percent magnesium carbonate.

Magnesian quicklime--derived from limestone containing 5 to 35 percent magnesium carbonate. Dolomitic quicklime--derived from limestone containing 35 to 46 percent magnesium carbonate.

Depending upon the type of quicklime used and the hydrating conditions employed, the amount of water in chemical combination varies, as follows: High calcium hydrated lime--high calcium quicklime produces a hydrated lime containing generally 72 to 74 percent calcium oxide and 23 to 24 percent chemically combined water.

Dolomitic hydrated lime normal --under atmospheric hydrating conditions only the calcium oxide fraction of dolomitic quicklime hydrates, producing a hydrated lime of the following chemical composition: 46 to 48 percent calcium oxide, 33 to 34 percent magnesium oxide, and 15 to 17 percent chemically combined water. Dolomitic hydrated lime pressure --this lime is produced from dolomitic quicklime under pressure, which results in hydrating all of the magnesium oxide as well as all of the calcium oxide, producing the following chemical composition: 40 to 42 percent calcium oxide, 29 to 30 percent magnesium oxide, and 25 to 27 percent chemically combined water.

What about physical specifications for lime? Quicklime, however, is commercially available in a number of sizes the following definitions are derived from ASTM Standard C51 : Large lump lime--a maximum of eight inches in diameter. Pulverized lime--a typical size is substantially all passing a No.

Pelletized lime--one inch sized pellets or briquettes, molded from fines.
