Abstract
Roofing granules comprising agglomerated inorganic material, and building materials, such as shingles, that include such roofing granules. By fabricating roofing granules from agglomerating inorganic material it is possible to tailor the particle size distribution so as to provide optimal shingle surface coverage, thus reducing shingle weight and usage of raw materials. Additionally, the use of agglomeration permits the utilization of by-products from conventional granule production processes.
Claims20
A method comprising:
- obtaining ingredients comprising (a) a plurality of fragments of at least one of a rock, a mineral, or a combination thereof and (b) a binder, wherein the plurality of fragments of the at least one of a rock, a mineral, or a combination thereof comprises fragments having a particle size passing US Mesh 100 but retained by US Mesh 270;
- mixing together the ingredients to produce an unsintered agglomerated particle that is formed by agglomerating together the ingredients;
- and
- coating the unsintered agglomerated particle with a coating to produce a coated particle, the coated particle being configured to be applied to a sheet to form a roofing product,
- wherein the at least one of a rock, a mineral, or a combination thereof comprises at least one of basalt, metabasalt, andesite, rhyolite, or a combination thereof, and
- wherein the binder is present in the unsintered agglomerated particle in an amount of not more than 8 wt %.

A method comprising:
- obtaining ingredients comprising (a) a plurality of fragments of at least one of a rock, a mineral, or a combination thereof and (b) a binder, wherein the plurality of fragments of the at least one of a rock, a mineral, or a combination thereof comprises fragments having a particle size passing US Mesh 100 but retained by US Mesh 270;
- mixing together the ingredients to produce an unsintered agglomerated particle that is formed by agglomerating together the ingredients;
- and
- performing processing comprising at least one of heating, cooling, or a combination thereof upon the unsintered agglomerated particle to produce a processed unsintered particle that is configured to be applied to a sheet to form a roofing product,
- wherein the at least one of a rock, a mineral, or a combination thereof comprises at least one of basalt, metabasalt, andesite, rhyolite, or a combination thereof, and
- wherein the binder is present in the unsintered agglomerated particle in an amount of not more than 8 wt %.
3 more elements
A method comprising:
- obtaining a roofing particle, the roofing particle comprising ingredients including (a) a plurality of fragments of at least one of a rock, a mineral, or a combination thereof and (b) a binder, agglomerated together to form an agglomerated particle such that the binder is present in the agglomerated particle in an amount of not more than 8 wt %, and then subjected to processing comprising coating, to obtain the roofing particle, wherein the plurality of fragments of the at least one of a rock, a mineral, or a combination thereof comprises fragments having a particle size passing US Mesh 100 but retained by US Mesh 270, and wherein the at least one of a rock, a mineral, or a combination thereof comprises at least one of basalt, metabasalt, andesite, rhyolite, or a combination thereof;
- and
- applying the roofing particle to a sheet to form a roofing product.
