We installed a Baghouse, Dust Storage Silo, Knockout Box, Burner, and Mineral Return System with a surge and weigh hopper. All of the equipment except the Burner are Stansteel Products. The burner is a Hauck Megastar Burner. The personnel/Contractors that assisted in the installation include GRI Plant Operators, GRI Concrete Crew, Layman Electric, Stansteel, American Crane.
The baghouse supplies air to the asphalt plant and remove exhaust and dust created by the process of drying aggregates and mixing asphalt. The baghouse allows our asphalt plant to exceed EPA and Tuolumne County Air District standards
The equipment allows GRI to be more environmentally aware and energy aware in our asphalt production process. Where before we were wasting 3-5% of all aggregate products, now we have a full recovery system that allows us to recover and refeed that 3-5% as mineral filler product. The equipment has greatly reduced our air born emissions while increasing the quality of our asphalt mix.
