Top 25 Rollouts of 2012
Cemco and McLanahan collaborated to produce the industry’s first portable frac sand plant capable of producing two sizes of frac sand. The company says the plant transports easily from one site to the next, is highway legal, and meets all state DOT requirements for transport. The plant design features two units on separate chassis to keep it within the legally transportable height of 13.5 feet. The two units connect with four hoses to make a complete, integrated plant. Only two operators are needed to assemble and disassemble the plant, which is said to take less than eight hours. The self-erecting plant offers an average output of 150 tons per hour, and is built for continuous operation. A one-touch screen control panel regulates and determines the operation and characteristic of the entire plant. The electric-powered plant is designed with minimal moving parts to minimize maintenance and downtime.
Cummins says its QSL9 engine, with up to 400-horsepower output, meets Tier 4 Final near-zero emissions standards with a next-generation compact catalyst and selective catalytic reduction (CCC-SCR) after-treatment system. The company says the engine makes no performance compromises in order to meet the standard, retaining its proven fast engine response and reliability. The after-treatment system provides a fully passive, flow-through operation and enables the engine to further improve fuel efficiency over the current engine. Further, it is configured for a highly compact and flexible equipment installation. The CCC-SCR after-treatment will be available in multiple configurations, including switchback, horizontal, and vertical.
Deister Machine Co.
Deister’s new ultra-fines recovery system (UFR) is designed to recover ultra-fine sands and silts, allowing operations to eliminate or greatly reduce the use of settling ponds. The system enables producers to create a dry tailing or silt product for stockpiling for removal or as a saleable product. It is capable of recoveries to 350-400 mesh at feed capacities from 1,500 to 3,500 gallons per minute. The reverse-slope vibrating screen is available in sizes up to 7 feet wide and 12 feet long with solids capacities of up to 70 tons per hour. Victaulic connections allow flexibility and ease of maintenance. A sloped bottom plate promotes even solids flow to the pump inlet, and an automatically adjusted make-up water valve protects the pump. A hand-railed stairway and platform on both sides and back of the screen allow safe and easy maintenance access.
How we made our choices
When we ask readers how we can best help them keep track of changes in the products and services they use to produce aggregates, almost everyone wants an annual short list of the really important stuff.
No wonder. The sheer volume of introductions is overwhelming. Aggregates Manager covers dozens of products each year in its RollOuts departments and Supply Lines features.
So each year, our staff reviews all the product introductions we’ve covered for the past year (our Top RollOuts “year” actually runs from the December 2011 issue through the November 2012 issue) to pick out 25 that we believe are worth further review. Our priorities are new concept products, which are rare; new series/new generation products in categories that relate to the aggregates industry; and other rollouts which serve our readers’ interests by increasing competition in a product category.
Inevitably, we omit deserving products, either because we just didn’t understand the significance of the product or because the announcing company didn’t communicate what was special about the product, or both. In either case, we apologize in advance for these omissions.
