Overall, Carmeuse’s milled limestone products are used in the following industrial applications:

  • Roofing Shingles
    Milled limestone has long been used as filler in the fabrication of asphalt roofing shingles. Asphalt shingles are the most popular and least costly form of roofing used in North America.
  • Animal Feed
    Milled limestone is used in animal feed as a source of calcium for healthy bone development and is essential to the formation of egg shells.  Carmeuse provides high purity calcium carbonate with a consistent particle size.
  • Flue Gas Treatment
    Milled limestone extracts undesirable gases from the air emissions of electric utility generation. Carmeuse mills chemical limestone to the exact requirements for your flue gas treatment process.
  • Glass Manufacturing
    Milled limestone is used in the production of soda-lime glass and fiberglass as a flux for modifying viscosity, increasing physical and chemical wear resistance.

    Milled limestone is a component of the latex adhesive on the back of carpet that holds the fibers in place.  Increased durability and lower manufacturing costs are achieved by using milled limestone.
  • Coal Mine Safety Dust
    Milled limestone, referred to as “rock dust”, is spread on the roof, ribs and floor of an underground coal mine to render coal dust inert.  Carmeuse is pleased to provide this safety measure that has proven to save lives.
  • Construction
