Horizontal Screens from KPI-JCI and Astec Mobile Screens deliver high productivity in a low-profile package. The triple-shaft design employs an oval motion stroke pattern that generates a more aggressive screening action to reduce plugging and blinding while providing extended bearing life. These innovations, in conjunction with other features like huck-bolt construction and a triple-shaft design, ensure our horizontal screens are the most durable and efficient screens available
SCREEN FEATURES Heavy duty 18” feedbox, 4" heavy duty discharge lips, and bolt on tailgate Larger shaft assemblies than standard JCI screens Flat top deck with bolt pattern for punch plate Bottom deck rail spacing set up for coarse screening (bottom decks 5' : 3 rails, 6' : 5 rails, 7' : 6 rails ) Bolt pattern for adding extension to top of screen Huck-bolted assembly Three shaft adjustable oval motion stroke pattern Quickly adjusts to a finer or coarser screening application by adjusting stroke angle, length and speed Fully contained oil splash lubrication system Standard scalper screen includes belt guard, motor mount, drive belt, drive sheaves Utilizes keyless hub to shaft locking assembly system Six superior load carrying double-roll bronze cage spherical bearings Balanced to accept various length discharge lips Rubber springs to reduce basket, gear, and bearing stress (Also reduces noise) Low overall screen height for portability No welded-on sidehill washers Favorable shaft assembly location under center of gravity of basket Bolt-in bottom deck bracing reduces deck/basket stress Single crown bottom deck (514 with 7' long drawplates) (516, 616, 620, & 720 with 4’ long drawplates)
