Screenin gThe Combo ® Screen is also the only multi-slope design thatfeatures a triple-shaft design. This design provides an optimaloval screening motion that has proven effective overdecades of success in the company’s traditional flat screendesign. In addition to the features of the Combo ® design,producers will also benefit by having the ability to adjuststroke length, stroke angle and RPM speed to best suit theconditions of the application.The end result is a machine that:1) Provides increased feed production by as much as20% over standard flat or incline screens;2) Maintains or improves the screening efficiency of separationfound on horizontal screens;3) Reduces material spillover at the feed end from highvolumes or surges of feed material;4) Improves the bottom screen deck’s utilization, therebyincreasing volume and efficiency.Although not as portable as the traditional horizontalscreens, the Combo ® design will be an ideal screen fora variety of both scalping and product sizing applications.The design is especially well suited for acceptinglarge volumetric feed ‘surges,’ deposits containing a highpercentage of fines that must be removed, installationswhere screening capacity must be increased within thesame structural or mounting ‘footprint,’ or in closed circuitwith crushers.Combo ® Screens are available in both a standard-dutyand finishing-duty three-deck configurations and arecurrently available in 6’ x 20’, 7’ x 20’ and 8’ x 20’ sizes.Combo ® Screens feature huck-bolt construction, inclinedeck panels that slope from 20 to zero degrees, adjustablestroke amplitudes, a hinged tailgate rear sectionfor maintenance access, and a perforated feed box foradditional screening area. Combo ® Screens can beinstalled with either standard wire cloth or urethane/rubber deck panels.164
