FEATURE Paglio. "It gets us to within 2.5 percent of the American Petroleum Institute (API) spec. From that process on, we produce multiple grades of wet product in different piles, and we can select which product we send to the dryer. Then we run it across just one bank of screen rather than multiples to keep the product in spec, and make sure there are no overs or unders. This allows us to produce up to 250 tph." Power Production Production at the plant begins with Volvo loaders feed‐ ing material over a Kolberg‐Pioneer scalping screen, which removes oversize material and any tramp metal. The material is then conveyed to the plant's screening tower. "We installed a large Deister screening operation and a couple of McLanahan classifiers," Paglio said. "With those in place, coupled with the Hydrosizer, we are able to produce multiple grades of frac sand." Water from the production process goes to a settling pond, and is recy‐ cled back into use. As part of a recent expansion, Southern Ohio Sand de‐ cided to erect a new building to contain its drying processes and testing lab to ensure a clean, consistent and dry product. The new building, which is 300 x 86 ft. with a height of 53 ft., encompasses two rotary dryers and screening as well as some storage. Bagging operations are also lo‐ cated inside this building. The company can bag sand and gravel from super sacking to 50‐lb. bags. 24 ROCKproducts • JANUARY 2013 Finished product is conveyed to storage silos where it is kept dry while waiting for loadout. "We have been very pleased with how the plant we set up has worked out for us," Paglio said. Transportation Logistics Producing frac sand is one thing, getting the product to market is another. "Our plant is in a rural area, as many are, so we truck material out of the plant," Paglio said. "We load trucks out, and serve a 600‐mile radius, deliv‐ ering either directly to the site where hydraulic fractur‐ ing is occurring, or to storage depots." In some cases the company trucks material out to its rail head, which is about seven miles from its facility, where they have an off‐loading unit. But they primarily deliver material by truck. The company works closely with nearby towns on issues such as adequate roads and truck noise. "We sometimes run 100 truckloads a day, so you have to address the people in the neighborhood, and not stir the pot," Paglio said. Southern Ohio Sand believes strongly in plant safety. It received an Industrial Minerals Association – North America (IMA‐NA) safety award for 2011. The company was recognized in the Small Category and went 12,131 hours without a reportable injury. Company manage‐ ment was congratulated for this achievement during a Safety Recognition Luncheon which was held in Wash‐ ington, D.C., on Thursday, April 26, 2012, in conjunction with the 2012 IMA‐NA Spring Meeting.
