Metso introduced its MX cone crushing technology. According to the company, the Metso MX is based on the company’s multi-action crushing technology that combines the piston and rotating bowl into a single crusher. Designed for the most demanding rock conditions and with a focus on automated adjustment features, the Metso MX provides a high reduction ratio with a premium end product shape and consistency critical in aggregate applications, Metso says. The key benefit of the multi-action technology is the easy under-load setting adjustment and wear compensation without having to stop the process, Metso adds.

Terex MPS, meanwhile, developed the CRC1150S portable closed-circuit plant, which features the TC1150 300-hp Terex cone crusher and TSV6203 6-ft. x 20-ft. triple-deck screen. Other key features include a metal detector on the main feed conveyor and tri-axle suspension with 57.5-in. axle spacing. There’s also a quick-release hopper with an integrated overflow chute system, a 42-in., 20-hp main feed conveyor, impact rollers in the feed hopper, a rubber discharge hood, a 36-in., 10-hp under-crusher conveyor and a four-section blending system.

Another unveiling, Kleemann’s MCO 11i PRO cone crusher, is designed for tough, demanding quarry applications. A diesel-electric drive powers the cone crusher, achieving an output of up to 518 short tph. The plant can be equipped with an external power supply for even more efficient operation, the company says. Because the hydraulics are installed in the lower part of the plant, the MCO 11i PRO has a low center of gravity, offering more stability and reducing noise and vibrations to a minimum, the company says.

Also, Johnson Crushers International released its 500-hp, remote-adjust Kodiak K500+ cone crusher. The K500+ is part of the Kodiak Plus family, which consists of three other models: the K200+, K300+ and K400+. The K500+ fills the demand for larger secondary and tertiary cone crushers that are used by high-production aggregate producers and mining companies, the company says. The Kodiak Plus product line includes a hybrid cast/fabricated base frame design, an automated control system, a liner retention system, a thread locking ring, anti-spin cone brake and other refinements.

Sandvik showcased its new CS550 cone crusher, which it’s touting as a powerful, secondary-stage crusher for 700- to 750-ton applications. According to Sandvik, the CS550 can be used in mining applications but its best use is in construction applications. The CS550 eliminates plastic backing materials in the crushing chamber. Also, the automatic setting regulation system, which comes as standard with the crusher, optimizes crusher operation for efficiency and adapts to variations in feed conditions by means of continuous liner wear measurement and compensation, the company says.

Telsmith introduced the latest crushing model in its T-Series: the T500. According to Telsmith, the T500 is a 500-hp cone crusher that’s designed to deliver maximum uptime availability while minimizing maintenance costs. The crusher contains a 14-in. maximum feed opening and can process between 285 and 755 mtph. One unique component of the T500 is the new hydrodynamic bearing feature. “This is truly different than any bearing arrangement in the industry,” says Jeff Gray, domestic sales manager at Telsmith. “A lot of people are using bronze bushings, more roller bearings. This uses a bronze and a steel component, and we actually use oil to separate that. So it’s actually floating on a film of oil. Theoretically it’s a lifetime component.”

ConExpo-Con/Agg was an opportunity, too, for Deister Machine Co. to showcase the EMCO 360 crusher optimizer feeder, which is the latest addition to the company’s line of electromechanical vibrating feeders. The EMCO 360 is engineered to optimize cone crusher performance, Deister says. Featuring a 360-degree discharge opening, the unit distributes a homogeneous feed to cone crushers, keeping cones choke-fed for optimum efficiency, product consistency and improved production rates.

Yet another cone crushing development emerged from Columbia Steel Casting Co., which displayed a new cone mantle design that offers improved crusher output based on initial field trials. According to Columbia Steel, it modified the cone mantle to direct feed more efficiently into a crushing chamber. The company found that filling a crushing chamber via typical gravity feed may not provide optimum, or maximum, material flow. Columbia Steel’s mantle design works by consistently drawing material into the chamber, producing a higher volume of crushed product. Early trials with customers in the Southwest and in Canada are promising, the company says.
