Processing Roofing Granules

3m classic roofing granules are dense non porous uv ray resistant and tough enough to stand up under handling.

Processing roofing granules. The 3m industrial mineral products division is part of that heritage. 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 typical process of transforming rock into roofing granule is outlined and illustrated below. All of our thermal processing equipment is engineered around the unique characteristics of the material to be processed to ensure an optimal.

We provide a wide range of thermal processing equipment for all of your roofing granule production needs including pre heaters combustion chambers rotary dryers rock dryers rotary kilns and rotary coolers. Made of a natural mineral product coated in ceramic the granules meet the toughest tests of time weather and visual appeal. 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. The durable high opacity granules have an ultra high reflectance that prolongs roof life and contributes to overall energy savings.

Mining processing locations. A roof containing white armor granules. These granules are colored with durable pigments bonded in a ceramic matrix and treated to promote adhesion to asphalt. Material processing thermal processing.

White armor cool roofing granules are specifically designed for use in modified bitumen roofing applications. 3m roofing granules are ceramic coated minerals used as surfacing material in asphalt roofing products. 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. The production of roofing granules is a demanding task mandating high capacity equipment capable of withstanding the rigors of processing roofing granules and providing long term reliability.

Using 3m science in processing coating and adhesives technologies allows us to improve the performance and durability of our granules giving manufacturers a better product that will stand the test of time. Producing quality granules for the roofing industry for over 85 years.
