Don't tell Michael W. McLanahan that manufacturing in the United States is dead. His family-owned, privately held company has made mineral processing and farm equipment since its founding way back in 1835 — and is enjoying a boom.
"It was our best year ever," said McLanahan, during a tour of the busy factory in central Pennsylvania that illustrates why manufacturing is growing twice as fast as the broader economy.
McLanahan, 73, is the fifth generation of his family to run the capital-intensive company. It builds equipment to help mining companies separate product from waste, the dairy industry to remove manure from sand and the energy sector to segregate gravel from silica sand used in fracking — the process of drilling through shale deposits thousands of feet below ground to reach natural gas.
