The new MR 110 Z EVO unit from Kleemann made its first appearance in North America at ConExpo-Con/Agg. The impact crusher features a new material flow concept — the discharge chute under the crusher is 4 inches wider than the inner width of the crusher, and the subsequent discharge belt is another 4 inches wider than the discharge chute. Rapid flow of the material keeps it away from the critical area under the crusher and reduces wear. An independent vibrating double-decker pre-screen is said to improve the cost efficiency of EVO units. A newly designed crusher bypass includes changes to its geometry and form to boost performance and reduce wear. Optional new and improved screening units are available and are more than 44 percent larger in size than those on previous units, allowing for tonnages of between 350 and 450 tons per hour.
