What industries are limestone powder used in?

The calcium carbonate content of limestone (commonly known as bluestone) is usually 92-93%, and its main impurities are magnesium oxide, silicon dioxide, aluminum trioxide, etc., with a block like appearance;

The calcium carbonate content of calcite is usually 93-98%, slightly higher than that of limestone. Its appearance is in the form of flakes, fibers, crystal clusters, etc., with complete surface cleavage and a Mohs hardness of 3;

Limestone is widely used as a building material and is also an important raw material in many industries.

After being extracted from limestone, limestone is crushed to form limestone particles, which are commonly known as stone (sand) or further crushed to form limestone powder. It is widely used in industries such as building materials, highway engineering, metallurgy, and chemical industry.

Limestone is transformed into calcium oxide (commonly known as quicklime) after calcination, and is used in water quality treatment, asphalt improvement, desulfurization, building materials, pharmaceuticals and other industries.

Lime includes quicklime and hydrated lime. The main component of quicklime is CaO, which is generally in the form of blocks, pure white, and light gray or yellow when containing impurities. Quicklime becomes hydrated lime by absorbing moisture or adding water. Hydrated lime, also known as hydrated lime, is mainly composed of calcium hydroxide Ca (OH) 2. Used in industries such as garbage incineration, environmental protection, medicine, and food.
