This week’s video, which was taken at Aggregate Industries‘ Sloan Quarry near Las Vegas, shows material that has been reduced to 8-inch-minus rock at the 1,300-ton-per-hour gyratory crusher in the primary plant being carried to and dumped into the surge pile. The conveyor running beneath the primary surge pile then picks up the material and feeds to the secondary plant for crushing and processing. The secondary plant is capable of processing approximately the same amount as the primary plant.
In the secondary, the 8-inch-minus rock is reduced to 1 1/2-inch minus and transferred to the secondary surge pile, which feeds three plants at the base of the mountain: a dry plant that supplies all the materials for the on-site asphalt facility, and two wash plants that supplies washed concrete rock and sand for ready-mix customers.
