11 AGGREGATES MANAGER July 2015 PLANT PROFILE The processing plant at Dolese Bros.' Davis Quarry is a copy of the company's Richards Spur Quarry located near Lawton. The plant was designed by Roger Dolese with future growth in mind. probably 75 percent of our business. That's the reason we built this quarry." Plant construction began in January of 1971 and was completed approximately six months later. The operation originally had a small outside plant, but improve- ments and additions were made over the years until a new fractionated blending plant was built in 2006. The new plant is a copy of Dolese's Richards Spur Quarry located near Lawton, which was built in 1951. Roger Dolese, the son of one of the founding brothers, designed the plant with an eye towards future growth. "Roger Dolese didn't think about to- morrow, he thought about 100 years from now," Coll says. "It's a good design. We've made some improvements to it since it was put in, but it's still the same design. We only use half of our crusher building. There are four crushers on one side along with all the extra equipment that goes with them, but there's room for another four-crusher set up on the other side. We'd have to build another mill to handle the extra load, though." The plant includes a 42-inch gyratory crusher, which was used at a couple of Dolese's other quarries before coming to Davis. The gyratory crusher is one of a few in the country that is designed to be portable. Dolese engineers designed a mobile structure for the crusher system that enables it to be moved throughout the quarry. "It only takes three days to move the crusher," Coll says, explaining that it doesn't matter whether it's moved just 100 feet or a mile. "It takes a day to dig it out, a day to move it and set it up, and another day to get it all tuned up and running again. We used to move it every three months to keep it within 300 feet of the shot rock and fed it with 992 Cat loaders from the sides. Two years ago, we parked it and now feed it with Kom- atsu end-dump trucks. That has been more efficient."
