The track-mounted GT440 from KPI-JCI and Astec Mobile Screens features an Andreas 4240 Horizontal Shaft Impact (HSI) crusher, available in a three- or four-bar rotor configuration. The GT440 uses a vibrating grizzly feeder (VGF) with a large hopper, and with an optional grizzly pre-screen designed to keep the crusher fed and operating efficiently. The grizzly pre-screen consists of independent vibrating fingers that resist blinding and plugging. The replaceable pre-screen module provides multiple settings for scalping unwanted material. The crusher’s hydraulic drive optimizes crusher capacity without sacrificing blow bar wear, according to the manufacturer. The 5 x 10-ft., two-deck screen offers 100 sq. ft. of screen area.
