Dexter Sand and Gravel Removes Lignite With Lites-Out™

Videos

Dexter Sand and Gravel discovered a great sand deposit and began producing sand for concrete there in July 2012. The only challenge with their new site was it contained trace amounts of lignite, a material similar to soft coal. Dexter Sand and Gravel was concerned with the quality issues caused by the lignite, and turned to McLanahan Corporation for a plant that could separate the lignite and make the desired product. Dexter settled on a McLanahan Lites-Out™ System, which uses a pulse-type discharge to induce a jigging action to free the lignite. The McLanahan Lites-Out™ System allows Dexter Sand and Gravel to meet their gradations and remove any trace amounts of lignite.
