www.concreteproducts.com March 2017 • 35 COVER STORY ERNST OF GEORGIA An MPAQ Automation package runs bins feeding the new Lawrenceville plant. In lieu of loader operator monitoring, the PLC-based control system takes bin level indicator signals and automatically keeps overhead aggre- gate compartments full. The Lawrenceville upgrade saw the addition of an energy-efficient, 10,000-gal. Pearson tank supplying the new and existing batch plants. Ernst staff members find the vessel much more energy efficient than a prior hot water source. Performance insulation sustains target or near-tar- get water temperatures days after a heating cycle. A two-tanker, eight-dump fleet—not hiding an owner- ship message unique for a multi-plant, Atlanta-area oper- ator—serves two Ernst Georgia divisions. Here, the new Ernst Enterprises of Georgia plant re- ceives a load of fly ash. A tank- er with less decorated tractor handles powder transfer to the Lawrenceville silos from the neighboring National Cement terminal.
