Tier 4 Final engines

MTU’s new Tier 4 Final diesel engines were developed to meet EPA standards without the use of exhaust gas after-treatment in engines above 750 horsepower and no diesel particulate filter at any horsepower. The 2000 and 4000 Series engines are used in mining and construction applications. The Series 2000, a family of 12- and 16-cylinder V-engines with power ratings from 760 to 1,560 horsepower, is said to deliver up to 10 percent better fuel economy and have extended exchange intervals for major components such as injectors and high-pressure pumps. The engines combine four key technologies, including the following:

• Cooled high-pressure exhaust gas recirculation (EGR), • Common rail fuel injection, and

• Regulated two-stage turbocharging, • Advanced diesel engine controller (ADEC).

Next generation crushing technology

Sandvik Mining says its new Vibrocone crusher is the next generation of crushing technology, combining the best of conventional crushing and grinding principles to produce a finely crushed product, while enabling up to 30-percent energy savings in downstream processing. It is said to open the possibility for new eco-efficient crushing alternatives. In existing crushing circuits with rod and/or ball milling stages, it can replace the rod mills or act as pre-grinding units for the ball mills.

Ultra-fines recovery

Deister Machine Co.’s new ultra-fines recovery system (UFR) is designed to recover ultra-fine sands and silts, allowing operations to eliminate or greatly reduce the use of settling ponds. The system is capable of recoveries to 350-400 mesh at feed capacities from 1,500 to 3,500 gallons per minute. It uses a radial distribution manifold for even distribution of solids to all cyclones. The reverse-slope vibrating screen is available in sizes up to 7 feet wide and 12 feet long with solids capacities of up to 70 tons per hour. System cyclones are available with a variety of liner and body materials. A sloped bottom plate promotes even solids flow to the pump inlet and an automatically adjusted make-up water valve protects the pump.

Mine-duty crusher

Telsmith, Inc. says its new T900 cone crusher is engineered to deliver maximum uptime, productivity, safety, and ease of maintenance. Output capacity ranges from 550 to 2,100 metric tons per hour. With up to a 15-inch feed size, the crusher is said to be rated with the largest-in-class clearing stroke, the highest-in-class crushing force, and 900-horsepower performance. The crusher is designed with eight cylinders and offers a new, patent-pending anti-spin feature that prevents head spin to extend manganese life. The unit is nitrogen-free and engineered with a patented release system that eliminates the need for maintenance-intensive hydraulic accumulators.

Hybrid-style crusher

McLanahan’s new rocker tooth crusher is a hybrid style of crusher — kind of a cross between a hammermill and a single-roll crusher with pivoting teeth. It is a high-tonnage machine capable of a large crushing ration in a single crushing station. The crushing hammers are designed to be larger and heavier than in a hammermill, while incorporating a semi-fixed “rocking” design that allows processing of larger lumps of feed material. Special design features include an oversized, heavy-duty upper and lower enclosure; a heavy-duty, wear-resistant liner package; rocking hammers; special wear-resistant hammer metallurgy; a wear-resistant, perforated-plate crushing deck; and an optional v-belt drive package or direct-coupled drive package.
