Arthur Taggart, Columbia and Yale Universities
Two of Arthur Taggart’s works, the “Handbook of Ore Dressing” and “Handbook of Mineral Dressing” are essential text for nearly every aspect of aggregates processing, as nearly every piece of equipment involved in processing is based on his research. Taggart gained mining experience as a machine operator, mill sampler and surveyor early in his career. But the classroom is where Taggart shined most, teaching at Yale University’s Sheffield Science School for most of the 1910s as an instructor and assistant professor of mining. His career shifted in 1919 to Columbia University, where he became an ore-dressing professor. Keep Reading
Samuel Calvin McLanahan, McLanahan Corp.
Samuel Calvin McLanahan designed nearly all of the equipment that came out of the foundry from the time he purchased one-sixth of McLanahan Corp. in 1880 to the conclusion of his tenure as general manager in 1902. Around 1890, Samuel conceived a way to wash clay from the rock in his family’s phosphate deposits in Florida. Inside a long wooden box, he mounted wooden logs and attached cast-iron paddles to them. Shortly thereafter, Samuel realized the need for a simple primary crusher that could handle wet, sticky feeds containing pieces that were too large. So in 1894, he invented the single-roll crusher to deal with the problem. Keep Reading
Charles Luck Jr., Luck Stone
In 1923, Charles Luck Jr. purchased the Sunnyside Granite Co. in Richmond, Va., and he ran the company that is currently the 11th largest crushed-stone producing company in the U.S. over four decades. Luck’s company started as a single quarry on the west end of Richmond. Today, Luck Stone operates more than 15 plants in Virginia and North Carolina, and it’s still in the family’s hands. “Our company’s success is based on people, not necessarily machines,” says Charles S. Luck III, current chairman of he board for Luck Cos. “My dad taught me that if you treat people fairly, then they’ll treat you the same.” Keep Reading
Charles W. Ireland, Vulcan Materials Co.
The company that eventually became Vulcan Materials Co. traces its roots back to 1910, but Vulcan’s rise into mega-producer territory is largely credited to Charles W. Ireland, a member of the third generation of Irelands involved in the company. By 1951, Ireland developed a plan to capitalize on increased automobile ownership that subsequently led to an increased demand for crushed stone. The demand increased further after 1954, when a commitment was made to build a $50 billion interstate highway system across the country. In 1956 and 1957, Ireland directed the company’s transition to a public corporation. Keep Reading
LeRoy Hagenbuch, Philippi-Hagenbuch
LeRoy Hagenbuch, co-founder and president of the engineering firm Philippi-Hagenbuch, introduced the first commercially available tailgate, the Autogate, for off-highway haul trucks. Hagenbuch is credited with other inventions and refinements, as well, including specialized liner packages to mitigate the weight consumed by liners and on-board weigh systems commonly found on haul trucks. A recent patent of Hagenbuch’s refines rear-ejection technology, allowing operators to push the load from the back of a haul truck instead of raising the bed. Keep Reading
Emil Deister, Deister Machine Co.
Emil Deister, the founder of Deister Machine Co., served as the company’s president and general manager from 1912 until his death in 1961. Under Deister’s leadership, the company began manufacturing vibrating screens in 1926 for the separation of materials according to particle size. Seven years later, Deister introduced a special screen for sizing the aggregate used in hot-mix asphalt plants, and the company subsequently added vibrating feeders and foundry equipment.

Rexnord Corp.
Rexnord Corp. is offering an inching drive option for the Falk V-Class gear drive, a line the company has designed for maximum uptime and durable performance. According to Rexnord, the optional standard package enables the V-Class gear drive to offer reliable full load inching operation. This allows slow-speed operation of equipment for inspection and maintenance purposes. It can also be run continuously to prevent freeze-up of components in harsh and cold weather environments when facilities may not be in production. The inching drive utilizes a Falk Ultramite gear drive that is integrally mounted to the main gear drive unit coupled via an overrunning clutch. This allows the inching drive to be automatically disengaged when the main motor is operating. www.rexnord.com Keep Reading
McCloskey International
McCloskey International is offering the same power units installed on its stacking conveyors as a standalone product. Available in 49 hp and 90 hp, the units have the same power and reliability as those installed in the full line of McCloskey stackers. Powered by a Kubota engine, the units feature high total hydraulic flow, with 26 gallons per minute (gpm) for the 49-hp unit and 38 gpm for the 90-hp unit. Both feature hydraulic oil coolers, which offer a safety shutdown. In addition, the units sport a 6-gpm auxiliary pump, and both are compatible with a broad range of products on the market. www.mccloskeyinternational.com Keep Reading
Komatsu America Corp.: WA320-7
Komatsu America Corp. introduced the WA320-7 wheel loader. With a net horsepower of 165 hp (123 kW), the WA320-7 is powered by a Komatsu SAA6D107E-2 engine and is EPA Tier 4 Interim and EU Stage 3B emission certified. Komatsu designed a more environmentally friendly engine, which decreases fuel consumption by up to 10 percent, compared to the WA320-6. Weighing in at 33,731 lbs., the new wheel loader features improved efficiency, lower fuel consumption, improved operator comfort and enhanced serviceability to maximize productivity while lowering operating costs. www.komatsuamerica.com Keep Reading
