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
Terex Washing Systems: AggreSand system
The AggreSand system, which Terex Washing Systems (TWS) expects to launch this quarter, combines aggregate washing and screening with sand processing. Central to the development of the new plant is a modular design, pre-wiring and pre-plumbing that make setup quick and easy. Among the features and benefits is the H 12 hopper with 15.7 cu. yd. of capacity. The H 12 is available with an automatic tipping grid and a 12-ft. two-deck vibrating grid that's fitted with a variable speed belt feeder. A wide feed conveyor has a direct drive electric motor and gearbox arrangement. It will work at a 19-degree angle when feeding the AggreSand system. The 165R-3 three-deck, two-bearing rinsing screen isolates spray bars from all vibration, according to TWS. Also, the system offers the option of five conveyors – three aggregate and two sand. Direct-drive electric motors and gearbox arrangements power the conveyors. www.terex.com/washing-systems Keep Reading
W.S. Tyler: Hydro-Clean
W.S. Tyler’s Hydro-Clean washing system effectively cleans deleterious material from aggregates, minerals and recycled materials, and is ideal for use in clay-heavy deposits. According to the manufacturer, the results are cleaner products with higher selling value and profits from material that was previously considered waste. The Hydro-Clean uses up to 75 percent less water than traditional washers, and 15 percent less energy. Dirty material is fed into a vertical washing drum through a hopper and high-pressure, rotating water nozzles spread and wash the material. Hydro-Clean washing systems process up to 400 tph, and can be mounted to a chassis for mobility within a quarry or from jobsite to jobsite. www.wstyler.ca Keep Reading
Casella CEL: Microdust
Casella CEL's Microdust real-time dust monitor is a handheld device for assessing employee risk for exposure to dangerous levels of dust and aerosols. The new CEL-712 Microdust Pro uses a laser diode-based light-scattering sensor to instantly detect dangerous concentrations of airborne particles and aerosols in the workplace, for spot checks and walkthrough surveys, or when performing continuous evaluation of fast-changing environments. The device can be used independently to measure material processes, filter performance or to capture release events such as bag breaks. It can also be paired with a cyclone, filter cassette and sample pump for size-selective or gravimetric monitoring. www.casellausa.com Keep Reading
