25 AGGREGATES MANAGER March 2014 Supply by Therese Dunphy, Editor-in-Chief THE BIG CRUSH When it comes to primaries, this is a round-up of crushers will kick-start your processing operations. Diesel or electric impact plant Efficient performance Redesigned portable jaw crushers More performance, less maintenance The Grasan KRH1620 horizontal-shaft primary impact crusher plant is available in pit-portable and stationary models for high-volume aggregates and concrete/asphalt recycling operations. The crusher can reduce 24-inch limestone down to 6-inch minus in one step and produce a cubical-quality product at up to 800 tons per hour. The plant features a Hazemag 1620 APPH impactor with fully automatic hydraulic cylinder system for increased crusher capacity, smooth operation, and uniform products. The 50-inch high, 80-inch wide inlet accommodates incoming materials up to 36-inch cube. Grasan | Irock's RDS-20 primary crushing plant is said to be a highly portable, easy-to-operate mobile unit. It combines a closed-circuit design, high-performance four-bar impactor, and heavy-duty components for reliability, increased efficiency, and the precision to produce a uniform, cubi- cal product. It also is versatile enough for use across multiple industries and can process a variety of materials, including quarry rock, demolition debris, recyclable materials, and base rock for oil fields. Irock | Kleemann offers two new jaw crushers, the Mobicat MC 110 Ri EVO and MC 110 Zi EVO. The MC 110 Ri EVO has a vibratory feeder with integrated grizzly, while the MC 110 Zi EVO incorporates a vibrating feeder with an independent, double-deck, heavy- duty prescreen. The crusher inlet on each unit is 28 inches x 44 inches. The machines now boast lighter transport weight to ease portability. The redesigned machines include features such as the hopper walls integrated in the chassis and a fully hydraulic crushing gap adjustment. Kleemann | The new generation Vanguard Jaw Crusher is said to reduce maintenance and increase performance. The optional tramp iron relief system enables adjustment to the closed- side-setting on the fly while providing overload protection from tramp iron events. KPI-JCI says the increased stroke, toggle angle, and flywheel inertia provide up to 25 percent more production, greater efficiencies, and lower fuel costs over competitive models. Components such as the common flinger collar, stress-relieved base frame, and machined saddle work to reduce cost of ownership. KPI-JCI |
