Eliminates the need for tertiary crushing
Hazemag says its Hazemag APS Series secondary impact crusher is ideally suited to crush materials of medium hardness down to a cubical, well-graded product size of 0 to 3 inches (with 65 percent passing 1 inch) in a single pass. Due to its high reduction ratio, the unit can often eliminate the need for multiple secondary or tertiary units in plants where they are present. The APSH model includes a hydraulic apron adjustment to ensure continuous production of high-quality, consistent product gradation. The computer-controlled, fully automatic hydraulic system is said to reduce the downtime normally associated with apron adjustments to minutes. Hazemag | www.hazemag.com
Streamlined secondary and tertiary crushing
McLanahan Corp. expanded its product line to include cone crushers. Capable of secondary, tertiary, and quaternary crushing, the units feature top-down maintenance. Safe unblocking is also engineered into the cone, with no need to dig it out when stalled. Simply press a button to open and restart when fully opened. Streamlined design features include an all-roller bearing design, simple hydraulic controls, and easy manganese changes. McLanahan Corp. | www.mclanahan.com
Steep feed angle, fewer parts
Metso introduces the Nordberg NP15 impact crusher, designed for secondary and tertiary crushing applications. It features a steeper feed angle to improve crushing efficiency and produce more end product with less recirculation load. It accepts feed material up to 15 3/4 inches and can be equipped with a 476-horsepower motor on a single drive. Its maximum throughput capacity is up to 12 percent bigger than the existing NP1315 impact crusher. The number of different side-liners has been cut nearly in half, compared to its predecessor, with only seven different liners. The IC2000 NP Automation system gives accurate control of the crusher parameters for a high-quality product and improved plant profitability. A wide range of blow-bar options is available to ensure the tool matches the abrasiveness of the material. A new two-part rear frame offers easy and safe access for maintenance. A removable breaker plate cassette ensures safe changes of breaker plate liners, while a maintenance bridge offers safe and easy access to both the highest side-liners and the rotor. A patented Self Rotation Rotor is the centralized point for adjusting the settings and changing the blow bars. Metso | www.metso.com
Dual crushing options
Sandvik Construction continued to expand its Prisec line with the introduction of the CI531 primary and CI532 secondary Prisec 3 horizontal shaft impact crushers. As with the rest of the product line, the HSI crushers can be configured into either a primary or secondary crushing mode. In addition, single-stage crushing is also an option with the ability to recirculate material to the primary versions of the crushers. A new crushing chamber design is said to allow for impressive reduction ratios through the use of two uniquely designed curtains, which have traditionally required a three-curtain configuration crusher. The maximum feed size is 39 inches in the primary configuration and just under 14 inches in secondary operation. Throughput ranges from 441 to 772 tons per hour as a primary and 276 to 441 tons per hour as a secondary.

Highest-in-class crushing force
With 402-horsepower performance and a crushing capacity output range of 150 to 600 tons per hour, Telsmith says its T400 Cone Crusher boasts the largest-in-class clearing stroke and highest-in-class crushing force. The cone features a large clearing circuit, which is engineered to safely and quickly allow any uncrushable material to pass. With a maximum feed opening of 12 inches, it has a 52-inch diameter head and a 55-inch receiving hopper. The crusher uses a single bowl for all liners over its range of operation. It also features a new and improved patent-pending anti-spin feature that prevents head spin to extend manganese life. A patent-pending concave (bowl liner) retention system achieves retention without the use of hammers or hand tools. The unit also features the largest-in-class, patent-pending hybrid bearings. The bearings feature a washer and ramp design that replaces the conventional use of a socket, socket liner, and head ball. They not only streamline service, but also offer both static and dynamic lift to efficiently carry the crushing forces. Telsmith | www.telsmith.com
REMco introduces its PROcone series of cone crushers for secondary and tertiary applications. Designed to be low-maintenance with a cast mainframe, bronze eccentric, and mainframe bushings, it boasts a large feed opening that remains consistent throughout the life of the manganese. No backing is required on the wear liners, making for fast change outs. Push-button, hydraulic controls provide quick adjustments on the closed-side setting. Hydraulic tramp iron relief protects the crusher from damage due to the passage of uncrushables through the machine. Multiple liner configurations and several eccentric throws are available to tailor the machine and liners to the application. A dual pump lubrication/hydraulic system uses the same oil type and weight for both hydraulic and lubrication to streamline maintenance and lower inventory requirements. An assortment of optional accessories and installation kit are available. REMco | www.remcoprocone.com
Mobile Tier 4 Final cone crusher
Kleemann says its new Mobicone MCO 9i EVO/MCO 9i S EVO mobile cone crushers offer high-productivity secondary or tertiary crushing in a fuel-efficient, Tier 4 Final emissions-compliant machine. The S-version provides a discharge conveyor-mounted final classifying screen with oversized aggregate return conveyor that permits a closed material cycle and production of final particle sizes without a standalone screen. The oversize can also be discharged via the swivel-mounted return conveyor at the side. The unit’s diesel-electric drive provides low fuel consumption in a compact design. Optional crusher anti-spin and automatic lubrication functions make for high crushing capacities and durability. Its power plant generates 332 horsepower at 1,500 rpm, and the optimized crusher housing design permits more than 287 horsepower to be continuously available to the crusher. The cone diameter permits a raw feed capacity of 287 tons per hour, with a feed size maximum of 8 1/4 inches. Kleemann | www.wirtgenamerica.com
Cost-effective tracked impactor
KPI-JCI and Astec Mobile Screens offer its new GT440 Horizontal Shaft Impact Crusher. The track-mounted crusher features an Andreas 4240 HSI crusher, which includes a three- or four-bar rotor configuration, allowing the end user to select the best solution for the application. The unit uses a vibrating grizzly feeder with a large hopper and an optional grizzly pre-screen designed to keep the crusher fed and operating efficiently. The pre-screen consists of independent vibrating fingers that resist blinding and plugging. The replaceable pre-screen module provides multiple settings for scalping unwanted material. The crusher’s hydraulic drive optimizes crusher capacity without sacrificing blow bar wear. The 5- by 10-foot, two-deck screen offers 100 square feet of screen area and provides quick, thorough screening.

High-production portable plant
Terex Minerals Processing Systems introduces the Terex Cedarapids CFJ3750 plant, which combines a JS Series jaw crusher with a high stroke, 52-inch by 20-foot vibrating grizzler feeder to create a high-production portable crushing machine. The system boasts a new hopper design to handle severe primary applications, while the jaw crusher features improvements such as wedge release jaw dies and hydraulic-assist crusher settings. Isolation of the jaw reduces plant vibration, while the tail of the product conveyor lowers for operation, maximizing clearance under the crusher. The conveyor discharge adjusts to reduce material impact on the receiving conveyor.
