Kleeman Mobicone a High-Performance Crusher
A new 300-tph tracked mobile cone crusher – the Kleemann Mobicone MCO 11 – is now available for North America. Kleeman is part of the Wirtgen group of companies at booth 639.
With a 44-in. diameter cone crusher as its core, the Mobicone MCO 11 provides high-performance secondary or tertiary crushing. Its 15.7-cu. yd. large feed hopper is designed for direct feed from a primary crusher, or by wheel loader. The MCO 11 can accept feed of up to 10 x 10 in. (250 x 250 mm) in size.
A variable speed drive easily controls material flow from hopper into cone crusher, via a solid rubber belt 40 in. (1000 mm) wide. It’s fed by a performance-boosting vibratory feeder – with special wear sheets – that helps prolong feed belt life. To easily service the cone assembly and for transport, the feed conveyor can be retracted.
To protect the cone, a powerful electromagnet separates ferrous metal objects from the belt. For nonferrous metals, a metal detector stops the belt for removal of the scrap metal by hand.
The MCO 11 cone crusher itself is driven by a 270-hp motor. The crusher is mounted on rubber supports to reduce vibration in the chassis and the MCO 11 features easy setting of the cone gap. A probe control ensures that the cone crusher is choke-fed for superior end-product quality. An extra-wide discharge conveyor belt moves product to screen or stockpile, and can be elevated to increase stocking capacity.
The Kleemann Mobicone MCO 11 features a high-performance diesel power pack, with diesel/electric drive rated at 483 hp (360 kW). Crawler tracks are actuated via an independent drive system. The MCO 11 is easy to move or reposition via wireless remote control.
All functions are operated from a single control cabinet, and the electrical control cabinets are protected from dust intrusion by an air overpressure system with multiple filters. The MCO 11 mobile cone crusher can supply electricity to external applications.
The MCO 11 secondary cone crusher complements Kleemann’s existing lines of Mobicat mobile jaw crushers and Mobirex mobile impact crushers. Kleemann Mobicone crushers may be electronically interlinked with Kleemann primary crushers and screens to optimize production and meet end-product requirements.
Metso C120 Jaw Combines Crushing Efficiency, Versatility, Safety
The Metso C120 jaw crusher is the 13th member of the field-proven C-series range of crushers. Metso’s C120 combines uncompromising reliability, crushing efficiency and versatility in both stationary and mobile applications with safety and ease of use, according to information the company shared at an Agg1 press event.
Metso’s durable and user-friendly design, begins with the casting, the design of which is based on thorough FEA analysis and casting simulations. Every detail of the C120 is engineered for reliable operation and long life, resulting in high, constant crushing capacity and uptime.
“When starting the C120 project, we listened closely to our customers and collected field data from a number of sites. Based on that, we decided to design the crusher cavity and kinematics first. As a result, Metso can now offer aggregates producers, large-scale contractors and mining companies a new crusher that meets all the standards set for any demanding application,” said Ilkka Somero, Metso’s product manager for jaw crushers.
The outstanding productivity of the C120 is due to several new design elements. The crusher features a long and aggressively directed stroke, and a fixed jaw die longer than previously seen in this crusher size class. The C120 has a large feed opening of 34 x 47 in., and an aggressive cavity cross section, with high performance and reduction ratio.
The C120 features optional robust composite flywheel guards that allow quick and safe access to all service points. The standard delivery includes lifting tools for jaw dies, cheek plates and toggle plate, contributing to operational safety when changing wear parts.
Philippi-Hagenbuch Offers Rear-Eject Truck Bodies
Philippi-Hagenbuch featured its line of rear-eject bodies at booth 1953 at the Agg1 trade show. Featuring safety, stability and increased productivity as hallmarks of its design, Philippi-
Hagenbuch’s patented line of rear-eject bodies offers the ideal solution for challenging hauling applications from general construction, road construction and sand/gravel, to mine reclamation and underground hauling situations where overhead barriers inhibit traditional dump bodies.
According to Josh Swank, sales and marketing manager, the truck bodies are easily adaptable to any make and model of articulated off-highway truck as well as a number of rigid frame trucks, the rear-eject bodies curtail the challenges associated with traditional dump bodies. In eliminating the need to raise the body of the truck, the Rear-Eject series allows for safely dumping materials while in motion and in the presence of overhead barriers. This versatility in operation increases efficiency without reducing stability by providing a lower center of gravity and allowing dumping on downhill slopes and conditions with a soft footing.
Enabling trucks to spread material while driving further enhances efficiency. The ability to effectively empty the truck without raising the body augments safety where overhead barriers such as power lines, roof lines or bridges may pose as forgotten safety risks, as well as in underground mining applications that have low overhead clearance.
Engineered to provide productivity-enhancing solutions for the toughest hauling challenges, Rear-Eject Bodies dump faster and easier – even in sticky applications. Without moving or raising the truck bed, the ejector blade pushes material toward the rear of the truck, while the tailgate lowers down and material is completely ejected. The unique sweeping action of the blade virtually eliminates all material – even that material prone to sticking to the sides or floor of the truck bed. This effective dumping action provides for more dumps in less time significantly increasing jobsite productivity.
Volvo L250G Wheel Loader a Two-Bucket Pass
The new L250G wheel loader from Volvo Construction Equipment, shown at booth 1205 where the company held a press event, fills the needs of the market for a machine in the 39-ton weight category. Designed to match the needs of on-highway trucks, the L250G is purpose-built to be a heavy-duty machine with plenty of power and features larger bucket sizes.
In North America specifically, when loading triaxle on-highway trucks, a new 9-cu. yd. rehandling bucket quickly fills the truck in only two passes. Add in strength and durability and the result is more loads in less time, meaning better onsite productivity. Volvo’s latest addition to its large wheel loader range combines the optimal mix of lifting force and traction, resulting in high bucket penetration.
The L250G has a sleek and modern appearance, as well as a new engine and driveline system for improved productivity, lower emissions, greater smoothness, serviceability and operator comfort. The L250G also features a powerful Z-Bar loader linkage that allows for high breakout force for digging in hard materials. Its heavy-duty linkage, lift arms and cylinders also offer high lift capacity and rapid hydraulic reaction, resulting in faster work cycles.
The L250G is fitted with a fuel efficient Tier 4i/Stage IIIB certified engine that is married to drive train, hydraulics and lifting systems that are all designed and produced by Volvo to work in perfect, productive, fuel efficient, harmony. The Volvo 13-liter, six-cylinder turbocharged V-ACT (Volvo Advanced Combustion Technology) off-highway diesel engine features cooled exhaust gas recirculation and a particulate filter with active regeneration. The active-type diesel particulate filter (DPF) temporarily holds the particulate matter and then incinerates it, further reducing emissions. There is no need to stop the machine in order to conduct the regeneration process; meaning no loss of performance or production.
Producing 290 kW (389 hp), this engine provides high torque at low engine speeds. As well as meeting the stringent low emissions requirements of the legislation (which came into force in January 2011), the D13 engine also leads the industry in terms of fuel efficiency. The production of torque and power at low engine speeds removes the need to overrun the engine, which in turn extends engine life as well as lowering fuel usage and dramatically reducing noise.

W.S. Tyler’s F-Class Vibrating Screen Features Independent Performance
The F-Class Vibrating Screen from W.S. Tyler, featured at booth 1912, is an ideal solution for challenging screening applications requiring minimal vibration transmission during operation. This allows for multiple machine use within the same building or structure without the same reinforcing measures required to house traditional vibrating screens. The F-Class is also ideal for screening situations that require consistent, load independent performance at constant G-Force in all operational modes.
Featuring a unique and reliable, proven four-bearing technology, the F-Class minimizes structural vibration and delivers a consistent stroke, which two-bearing screens cannot provide, and with right media choice virtually eliminates blinding and pegging. With the ability to handle the toughest applications, the F-Class is designed and built for scalping and classifying of ores, minerals, stones, sand and gravel.
According to company President Florian Festge, the F-Class features an advanced eccentric shaft design, supported by four high-performance, double spherical roller bearings. The double eccentric shaft creates a constant positive stroke that handle material volume spikes without losing momentum. As the eccentric shaft turns, the screen body is forced to follow the shaft movement. While it travels upward, the counterbalance weights move in the opposite direction and create an equal force to that generated by the body.
As a result, the forces cancel each other, allowing a dynamically balanced system that transmits minimal to no vibrations into the structure. This allows multiple screens to be placed side by side while minimizing the investments into heavy structures. Furthermore, the design keeps noise emissions low for a quieter system and reduced overall plant noise. These features are the reason, why demanding producers for products such as iron ore and phosphates as well as limestone utilize the F-Class in buildings housing up to 45 units over up to 8 stories while minimizing the investments into the required structures.
The continual circular screening action provided by the eccentric design also produces a constant, optimized G-Force. Not only does this further maximize screening efficiency, it allows the F-Class to be an effective solution in both wet and dry applications.
Designed for high tonnage outputs, the F-Class can process up to 5,000 tph, as well as provide fast, accurate sizing of virtually any material ranging in cut size from 0.15-in. to 9.76-in. In addition to traditional screening, the F-Class is often used before primary crushers to screen out fines and eliminate crusher wear. It precisely screens material from 6-in. down to 20 mesh.
