San Francisco Bay Area, California - June 2015
Over 90% of California’s 175,000 miles of road are surfaced with asphalt. Constant asphalt production is a requirement to create new roads for an ever expanding infrastructure and resurface old roads to reduce vehicle costs for California motorists. Rock Systems worked with a contractor in the Bay Area on a new asphalt plant, which will help the region meet its asphalt needs.
The contractor developed a sand and gravel deposit to produce construction materials and hot asphalt for paving. Rock Systems provided an engineered system including equipment to feed different sizes of sand and rock to a new 500 tons per hour asphalt plant. The material handling system provided by Rock Systems includes:
- Eight 30-ton capacity feed hoppers with adjustable rate 30” wide roller belt feeders to provide various predesigned mixes to the asphalt plant.
- A 36" wide collecting conveyor mounted under the belt feeders and two transfer conveyors, 36" wide x 58' long and 36" wide x 187' long, to direct the blended mixes to the plant.
- An electrical control panel to control the speed for each feeder with a high degree of accuracy.
