Caterpillar: 966K XE wheel loader
Caterpillar's 966K XE wheel loader delivers up to a 25 percent fuel efficiency improvement, the company says. The 966K XE utilizes an integrated, continuously variable transmission system. A hydraulic pump and motor allow for a smooth and continuous gear ratio change between engine speed and machine speed. According to Cat, the variator provides this ratio flexibility while reducing the heat load generated by the drivetrain when the machine is digging, pushing and climbing under heavy load. Power is transmitted through the variator unit, as well as a parallel mechanical gear path. Power through the variator and mechanical paths are combined through a series of planetary gear sets to maximize the transmission efficiency over a range of operating conditions. The unit's engine can deliver 290 hp. www.Cat.com Photo: Caterpillar Keep Reading
IRock: TS-409
The TS-409 open-style feeder track screening plant is one in a line of five IRock models the company has designed for small to midsized producers looking for a more economical, compact plant. The TS-409 can accommodate topsoil, mulch, sand and gravel, asphalt, coal, limestone and demolition debris, and it is powered by a 66.2-hp Deutz engine. The plant is capable of processing materials at a rate of up to 300 tph. It features an open-style hopper feeder with a 5.02-cu.-yd. capacity, and it has a 42-in.-wide belt feeder conveyor. www.IRockcrushers.com Keep Reading
Caterpillar: 349E hydraulic excavator
Caterpillar's 349E hydraulic excavator features a 396-net-hp Cat C13 engine that meets Tier 4 Interim emissions standards. The 349E delivers more engine and hydraulic horsepower than its 345D predecessor and averages 5 percent improved fuel efficiency in typical applications, according to Cat. The engine, which operates either on ultra-low-sulfur diesel fuel (ULSD) or a blend of ULSD and 20 percent biodiesel, uses the Cat Clean Emissions Module (CEM) to meet Tier 4 Interim standards. The CEM regeneration system is designed to be transparent to the operator and regenerate when the conditions are optimal with no operator intervention. In automatic mode, the regeneration system allows the machine to work as normal with no interruptions to the work cycle. www.Cat.com Keep Reading
Stedman
The Grand Slam Series of horizontal shaft impactors from Stedman uses high-chrome metallurgy to increase the wear life of machine components, reducing metal replacement costs. The series consists of 11 high-production models, with capacities ranging from 1,200 to 1,600 tph. The impactor design incorporates both primary and secondary aprons for maximum product control, eliminating the need for grate bars and discharge screens. The impactors’ two-stage crushing action produces more product on the first pass with reductions ratios up to 30:1, even while handling large and slabby feed material. A full-length rotor shaft with two, double-row spherical-type bearing assemblies features a taper lock design to strengthen the rotor for highest reliability. www.Stedman-machine.com Photo: Stedman Keep Reading
Metso: Lokotrack ST2.4
Metso’s newest mobile screen in the Lokotrack series, the ST2.4, is designed to combine high screening capacity with low fuel consumption. Metso says the combination has been achieved because of an optimized hydraulic design and the control system. The Lokotrack ST2.4 can classify a variety of materials, from the pre-screening of coarse gravel to fine classifying and processing of natural sands to demanding recycling materials. To meet a user's specific screening application need, the ST2.4 can be equipped with a variety of screen media, from steel meshes to Trellex rubber and polyurethane materials. The ST2.4 can also be equipped with a vibrating apron feeder with grizzlies or finger bars. www.Metso.com Keep Reading
Atlas Copco
Atlas Copco has released the latest addition to the ongoing reference book “Blasthole Drilling in Open Pit Mining.” The third edition was written to provide comprehensive reference on the use of rotary drills in surface mining applications. Twenty-one technical articles have been included to offer information that both experienced drill operators and industry novices can use. To provide real-world scenarios, 25 case studies highlight a variety of successful mining operations around the world. "Blasthole Drilling in Open Pit Mining" is available through local Atlas Copco customer centers and distributors. It can also be downloaded online. Also, Atlas Copco recently introduced the PowerROC T35 E, a new surface drill rig. The T35 E is an extendable boom version of the T35 drilling rig currently in use. www.AtlasCopco.com Keep Reading
KPI-JCI: Kodiak Plus K500+
The Kodiak Plus K500+, a new 500-hp, remote-adjust cone crusher, is the latest addition to the Kodiak Plus cone crusher family, which previously consisted of three models: the K200+, K300+ and K400+. KPI-JCI and Astec Mobile Screens are launching the K500+ model to fill a demand for larger secondary and tertiary cone crushers that are used by high-production producers. One refinement implemented into the Kodiak Plus line is a hybrid-cast, fabricated base-frame design. Other features are replaceable brass thread inserts, internal counterweights and a liner-retention system. www.KpiJci.com Keep Reading
W.S. Tyler: Haver Hydro-Clean washing unit
The Haver Hydro-Clean washing unit from W.S. Tyler cleans deleterious material from aggregate effectively while reducing water consumption by up to 75 percent and energy costs by up to 15 percent over traditional log washers, the company says. Taking a maximum feed material size of up to 6 in. into its vertical drum, the Hydro-Clean employs high-pressure nozzles, rotating at 90 rpm, to spray up to 90 percent recycled water on the material with pressures up to 2,900 psi. The washing unit removes silt and clay particles as small as 63 microns from mineral mixtures and, with its short retention times, can process up to 400 tph, depending on model size and application. Due to its compact size and weight, overall operating and structural costs are considerably lower than with traditional washing systems, the company says. www.WSTyler.ca Photo: W.S.

Sandvik: DI550 down-the-hole drill rig
The DI550 down-the-hole drill rig is a match for 5-in. hammer drilling, but Sandvik says the rig is also productive with 4-in. and 6-in. hammers. The DI550 is equipped with a 328-kw diesel engine and a 24.4-cu.-meter compressor airflow at 24-bar pressure. Sandvik says the DI550 includes smart automation features that prevent human errors, improve drilling efficiency and machine performance. Among the features is automatic systems control that supervises all machine functions, and one-pipe automatic drilling that makes the machine easier to use. The DI550 is equipped with Tier 4 or Tier 3 engine technology. An ambient dependent control for compressor running temperature prevents condensate, and, thereby, rusting. Furthermore, the rig is equipped with a new kind of heavy-duty rotary head for maximum rotary torque. www.Sandvik.com Photo: Sandvik Keep Reading
