Your complete guide to new and updated equipment and supplies in the aggregates industry. by Kerry Clines, Senior Editor 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 construc- tion 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 in- jectors and high-pressure pumps. The engines combine four key technologies, including the following: MTU; mtu-online.com. Text INFO to 205-289-3782, or visit aggman.com/info. Ultra-fines 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 en- abling 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. Sandvik Mining; sandvik.com.

The system is capable of recoveries to 350-400 mesh at feed capacities from 1,500 to 3,500 gal- lons 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. Deister Machine Co.; deistermachine.com.
