Processing Roofing Granules

The durable high opacity granules have an ultra high reflectance that prolongs roof life and contributes to overall energy savings.

Processing roofing granules.

For these reasons the industry relies on rotary drums to carry out granule production as these machines boast a heavy duty build high capacity. A roof containing white armor granules. As an aesthetic treatment of end laps and side laps on granule surfaced built up and modified bitumen membranes mineral shield roofing granules provide a multi faceted design and light reflective construction that adds dimension and depth to membrane products. Made of a natural mineral product coated in ceramic the granules meet the toughest tests of time weather and visual appeal.

3m roofing granules are ceramic coated minerals used as surfacing material in asphalt roofing products.

Prime roofing granules are the protective pixels of beautiful shingles. Mining processing locations.

3m classic roofing granules are dense non porous uv ray resistant and tough enough to stand up under handling. White armor cool roofing granules are specifically designed for use in modified bitumen roofing applications. While roofing granules may not look like much more than rocks they are actually a highly engineered product the result of advanced processing techniques that work to create a premium roofing granule product. A typical process of transforming rock into roofing granule is outlined and illustrated below.
